[Dovecot] dovecot 1.0-test69 io hangs
by Jens Laas 13 May '05

13 May '05

I've been testing test69 with pop3 (under Linux and with mbox). I began testing with a large inbox (11000 mails) and it seems the communication between dovecot and the mailclient (evolution) stalls after 1000-2000 messages transferred. I've looked in to the (non-trivial) io functionality of dovecot. What I see is that io_loop_handler_run() in ioloop-poll.c does not signal any more data (and eventually the whole thing timeouts). Evolution downloads the mailbox fine via qpopper. I tried turning on rawlog: mail_executable = /usr/libexec/dovecot/rawlog /usr/libexec/dovecot/pop3 I cannot find any logfile.. I must be missing something. Any help or ideas ?

[Dovecot] "shared mailboxes"
by schnitzel meister 12 May '05

12 May '05

Hello, After a long search I've almost settled on dovecot as a pop3 and imap server. I have just one problem.. Rather than have a list support(a)company.com, I'd like to have a shared mailbox. The dovecot homepage explicitly states "Shared mailboxes aren't _yet_ supported." The sentence implies that they're planned - any idea when? Thanks

[Dovecot] IDLE command timeout
by Sim Harbert 12 May '05

12 May '05

Is it possible to change the IDLE command timeout to be more than 30 minutes? I have a client on my PalmOne Treo 600 which will stay in IDLE mode as long as it can. I would like to set the timeout to something much higher than 30 minutes. Maybe several hours or even more. I don't see a configuration setting for this value in "/etc/dovecot.conf". Am I missing something? Thanks, -Sim

[Dovecot] 1.0-test69
by Timo Sirainen 11 May '05

11 May '05

http://dovecot.org/test/ - Several mbox fixes, upgrade recommended for test68 mbox users - Possibly fixes some IMAP hangs where Dovecot just stopped replying - Fixed delay-newmail workaround. It was badly broken before. And somewhat off topic advertisement: I got a bit distracted from Dovecot a week ago when a guy started mailing me about wanting to write an irssi2 client as a project to learn Ruby. Half a year ago I had written a semi-working irssi2 server but I got stuck with it because I wasn't interested about writing client for it. Now that the client actually works, irssi2's development has kind of exploded :) Irssi2 is a bit related to Dovecot too, in that it'll be integrated with it more or less tightly to provide instant messaging support. Nothing prevents extending irssi2-protocol to support all other kinds of realtime events either, for example to send new mail notifications. If you're interested, see: http://main.irssi.org/projects/irssi2.html And for the lazy, here's the introduction copy&pasted: Shortly put, irssi2 is to instant messaging what IMAP is to mail. You can safely exit your irssi2 client, and irssi2 server just keeps on going. When you connect back with your client, you can see all the discussion that happened while you were away (and even older discussion, too, if you want). You can also use multiple clients even at the same time, so you could for example keep one client always open at home and still be able to check what's going on with your mobile phone. Irssi2 clients are encouraged to keep their configuration in server side, so nothing should prevent you from temporarily using another irssi2 client from your friend's home with no other configuration needed than irssi2 server's address, your username and password. Irssi2 is designed to support multiple chat protocols (IRC, SILC, MSN, ICQ, etc.) but without ignoring hardcore IRC users. That means that unlike all other similar attempts (such as Jabber), irssi2's client-server protocol will actually allow fully featured irssi2 IRC client to be written with no compromises (but still the same client can be used to talk to MSN and elsewhere). Note that irssi2 isn't trying to replace IRC servers (yet ;). irssi2 server simply connects to normal IRC servers just as a regular IRC client. To prevent mixups with these terms, IRC servers are usually called "gateways" in irssi2.

[Dovecot] Dovecot Sendmail Maildir
by Gabriel Granger 11 May '05

11 May '05

Hi all, I'm using Debian (testing) for my office mail. I'm using sendmail and Dovecot to deliver email to clients over IMAP using mbox format. I want to move over and start using Maildir. I know that I can use different MTA's to do the job, but I really like sendmail, and I run additional sendmail servers across the my internal and external networks. I'm probably being anal, but I want to keep my MTA the same across the board. Does anyone here use sendmail + dovecot + maildir? if so what's the best way of going about this? Gabe

[Dovecot] Standard dirs
by Claudio Succa 10 May '05

10 May '05

Hi, thank to developers for such a flexible imap server. Is solves succesfully my needs to have a single passwd file for clients accessing both imap/imaps and pop3/pop3s protocols (on a diskless mail/web server with NFS maildirs and NFS indexes!). My question: With 1.0-test68 I have to set login_dir=/var/run/dovecot-login (just a dir not under /var/run/dovecot) instead of /var/run/dovecot/login. I guess that imap-login (running with uid=dovecot) can't access /var/run/dovecot/login if it is under /var/run/dovecot because it is set with permission 0700 and uid=root by dovecot. How can I run dovecot with its standard login_dir config?

[Dovecot] problems with ldap auth
by Nuno Lopes 10 May '05

10 May '05

I'm trying Dovecot v1.0-test43 with ldap authentication but can't seem to make it work. I'm getting the following errors in the log: dovecot: Sep 16 19:50:09 Info: Dovecot v1.0-test43 starting up dovecot: Sep 16 19:50:10 Error: Auth process died too early - shutting down What can I do to see where the error is? I have this configuration working with dovecot 0.99.xx . And if I replace the ldap authentication scheme with another one it starts up right. Following some past mailing list sugestions I've also tried removing most of the auth modules from the compilation but it made no diference. You can see my configuration files in: http://iluvatar.portugalmail.pt/dovecot/dovecot.conf http://iluvatar.portugalmail.pt/dovecot/dovecot-ldap.conf (I've intalled the binaries in /opt/dovecot) Don't know how much more data I can provide to help finding out what the problem is here (I think this won't be enough unless there's a known bug). Thanks, -- Nuno Lopes

[Dovecot] trouble getting digest-md5 & ldap working
by Udo Rader 09 May '05

09 May '05

hi, I am trying to set up dovecot with digest-md5 as authentication mechanism and openldap as passdb. My problem is ... that I just can't get it working. PLAIN authentication works as expected, but no luck with digest-md5. An excerpt from the two configuration files: dovecot.conf: --------CUT-------- auth = default auth_mechanisms = plain digest-md5 auth_userdb = ldap /etc/dovecot/dovecot-ldap.conf auth_passdb = ldap /etc/dovecot/dovecot-ldap.conf --------CUT-------- dovecot-ldap.conf: --------CUT-------- user_filter = (&(objectClass=posixAccount)(|(mail=%u)(uid=%n))) pass_filter = (&(objectClass=posixAccount)(|(mail=%u)(uid=%n))) default_pass_scheme = plain --------CUT-------- My dovecot installation with plain authentication and OpenLDAP has been quite mature for a long time, so I doubt that it is an issue with openldap. >From Cryrus-SASL I know that in order to get DIGEST-MD5 running it is required to have plaintext passwords in the DIT, but that does not solve anything. syslog tells me this: dovecot-auth: May 08 21:25:09 Error: ldap(frodo): No password in reply So any ideas on where I went wrong?

[Dovecot] transparent proxy
by Mark E. Mallett 09 May '05

09 May '05

I'm excited to see that dovecot 1.0-test series supports transparent proxy, but that excitement is muted by: - the recommendation to avoid 1.0 at present; - the requirement to use SQL authentication. I guess I could ignore the first, but the second is sticky. How hard would it be to hack a different sort of proxy server cue into the authentication? Perhaps one of: If authenticating via passwd, use a gid as an index into a server table (or perhaps have the group name be a server name), If passwd authentication fails, try a starting the proxy to a specific other server and see if one can log in there. Or something else.. I dunno, I'm just looking not to install a SQL server just for this. mm

[Dovecot] index file corruption
by Andy Pastuszak 09 May '05

Hello everyone. I am new to the list, so forgive me if this has been discussed already. My configuration is as follows: Fedora Core 3, fully patched through yum through today. Dovecot 0.9.9.13 Postfix 2.1.5 Using Maildir with Mail stored in ~/Maildir My issue is that, for some odd reason the inbox file index gets corrupt, There is no rhyme or reason as to why it happens or when, but a simple rm -rf ~/Maildir/.INBOX fixes everything (I assume because Dovecot rebuilds the index file.) Has anyone else on the list seen this? Is there some workaround for it? Andy

[Dovecot] dovecot 0.99.14 and imaps (SSL) "hangs"
by Frode Nordahl 08 May '05

08 May '05

Hello, I just decided to try dovecot again after a long pause, and I must say that I am very impressed with the speed and resource usage, even when running with UNIX mailboxes. However, I have a problem with SSL. Every two minutes the connection is frozen, and the client has to reconnect after it times out waiting for a response from the server. My IMAP client fetches all headers, and then caches all messages in my mailboxes. However, if I do this while connected to dovecot using SSL (imaps, port 993) the connection times out roughly every two minutes, and the IMAP client must close the connection, reconnect and resume operations from where it left off. This makes resynching a 40000 message 300MB folder take VERY long :-) Using the same client, connected to the same server and syncing the same mailbox connecting to regular imap port (no TLS, port 143), everything works smoothly. The very same client, server and mailbox works flawlessly with uw-imapd and SSL. I have turned on rawlog, and everything seems to be OK. I am unable to dump the wire, because it's SSL, so not sure what to do to debug this. One thing I find a bit strange is that /var/run/dovecot/ssl-parameters.dat is a 0 byte file. Is this normal? Client: Apple Mail 1.3.11 (v622) Server: dovecot 0.99.14, installed from ports on FreeBSD 5 dovecot.conf: Regards, Frode Nordahl

[Dovecot] pop vs. imap inconsistancy
by jeff sacksteder 08 May '05

08 May '05

I am converting from courier and have noticed change in behaviour with Dovecot. I use maildirs with squirrelmail connecting by imap as well as a POP3 client. Courier would set the 'mail status-read' flag for any message which was downloaded with the POP3 interface. Dovecot apparently does not. Is this a bug or intended behaviour? If it is intentional, can it be changed with the config file?

[Dovecot] Outlook Duplicates issue is still killing me
by Jeff Ramsey 08 May '05

08 May '05

Hi, I have one pop3 client who has three computers, and he has Outlook XP on two, and 2003 on the third. They are all set to leave a copy of messages on the server, and that causes a duplicate message for every message he gets. I then can tell him to uncheck the "leave a copy on the server" box, and pop his mail, and the duplicates will go away for two or three days, only to start up again. I have a stock Fedora Core 2 server with dovecot and Sendmail. I do a nightly yum, so as to stay up2date. My version of dovecot is 1.0-test42. Has anyone else seen this issue? What can I do to fix it, short of permanently unchecking that box in Outlook? (The user is my boss, and he likes to get his email on all three computers...) -- Jeff Ramsey MIS Administrator Tubafor Mill, Inc.

[Dovecot] Test68 and Namespaces
by Jim Summers 08 May '05

08 May '05

Hello List, I am in the process of building a new mail system here. I am hoping to eventually migrate my users from mbox storage to maildir. They have been using mbox forever and would rather get used to maildir slowly. So I have come upon the idea of using namespaces to provide the different mailstores. Since this isn't available in the current stable, or at least I could not figure out how to do it, I have been working with 1.0-test68 since it provides the ability to configure things with the namespaces. But I am seeing an error pop up in my maillog file when exiting the client, it is: ============================================ May 3 08:11:41 tbox dovecot: IMAP(sub4000): file mbox-sync.c: line 1371 (mbox_sync_do): assertion failed: (sync_ctx->mbox->mbox_sync_dirty) May 3 08:11:41 tbox dovecot: child 12717 (imap) killed with signal 6 ============================================ Wasn't sure if it is a code bug or if it is how I have the namespace entries setup. In my dovecot.conf file I have: ------------------------------------ namespace private { separator = / inbox = yes # prefix = "#mbox/" location = mbox:~/Mail/:INBOX=/var/mail/%u } namespace private { separator = / prefix = md/ location = maildir:~/Maildir } namespace private { separator = / prefix = mail/ hidden = yes } namespace private { separator = / prefix = ~/mail/ hidden = yes } namespace private { separator = / prefix = ~%u/mail/ hidden = yes } ------------------------------------ All seems to work except the message showing up in the logs. My goal/setup is to provide: 1. mbox delivery in the mailspool(/var/mail) from sendmail 2. access to existing ~/Mail/ mbox storage. 3. ability to begin setting up / migrating to maildir in ~/Maildir Is my namespace config above overkill / borken / wrong? Ideas / suggestions on this would be greatly appreciated. Environment: Server to be: RedHat AS EL4 Clients: Thunderbird, Evolution, mutt, pine, mailreader on OS/X.

[Dovecot] test-68 coredump
by Gregory Bond 08 May '05

08 May '05

I've tried upgrading from test-51 to test-68, with mixed results. It seems to fix the problem I had with imap and Thunderbird getting confused and not showing headers or body for some email. But something in dovecot is coredumping when I select certain mailboxes. Thunderbird just hangs when you select that mailbox, and mutt gets an EOF on the imap socket while "fetching message headers". Other mailboxes seem to run OK. The failing ones _might_ be empty or have only 1 message in them. Removing index files doesn't help. There is a core file in /var/run/dovecot, and file(1) says it's from dovecot-auth, but GDB can't make sense of the core with that executable, and the login has well and truly run when the core happens. (The core doesn't seem to be from the imap process either.) Any clues how I might debug this? [Solaris 2.8, gcc-3.3, dovecot test-68, imap+Maildir, Thunderbird 1.0.2 on OSX and mutt on Solaris]

[Dovecot] quota-command?

08 May '05

Hello, if you log in at hotmail.com, gmx, lycos or yahoo, you can see something like "using 1.4mb of 250mb total". Is there any IMAP command to check to current quota usage? Our webmail-interface will not have access to the filesystem to summarize the size of each file, so an IMAP-command would be great. I don't know if this would be a new feature or just part of the Maildir++ quota-system, that is not yet supported by dovecot. Regards Marten

[Dovecot] Migrating from courier-imap to dovecot
by Odhiambo Washington 08 May '05

08 May '05

Hello Gang, I am new to dovecot and the only reason (so far) I would like to use dovecot, and in production with 12k+ users, is the fact that it's supposed to be faster and less of a resource hog. Now, sometimes I am really good at reading the documentations but it sometimes happens that one overlooks something. I did read the migration notes three times! My users are in /etc/passwd and I am running dovecot in IMAP only mode. I did put default_mail_env = maildir:~/Maildir in dovecot.conf, then for one user, I did the following: cd ~wash/Maildir cp courierimapsubscribed .subscriptions # Then I edited to remove "INBOX." cp courierimapuiddb dovecot-uidlist The permissions are right, but when I login as this user, I don't see all the folders that had been there before when he was using courier-imap!! When I login to the web interface (we use Squirrelmail) and go to the Folder options, I can't see any folders to subscribe to either! Now my questions: 1. What am I overlooking?? 2. Does someone have a script that can be used to automate the copying of courierimapsubscribed to .subscriptions and that of courierimapuiddb to dovecot-uidlist, and the editing to remove the "INBOX."? I am sure I really don't have to reinvent the wheel, no? Meanwhile I am hitting google, while waiting for your answers.

[Dovecot] How to check for keywords in IMAP store?
by Steffen Kaiser 08 May '05

08 May '05

Hello, I'm checking my way to migrate from Courier to Dovecot. Wiki says that "there's currently no easy way to migrate them [the keywords]". Frankly, I lack the information to check if some client is using keywords at all. More importantly, is it OK to assume that when SELECT INBOX returns no \* in OK [PERMANENTFLAGS ...] that the IMAP server does not allow keywords at all?

[Dovecot] Setting location for indexes

We have NFS-mounted user directories which cause significant problems with stale file handles: dovecot: IMAP(uid): fstat() failed with file /home/uid/mail/.imap/INBOX/dovecot.index.log: Stale NFS file handle (a) why can't it just close the file and re-open ?

I have already tried 'mmap_disable = yes', but that does not solve the problem, and if I set 'default_mail_env = INDEX=/var/spool/mail/INDEX/%u', I get errors like: IMAP(uid): Failed to create storage with data: INDEX=/var/spool/mail/INDEX/uid I don't want to specify mbox:~/mail/ or mbox:~/Mail/, because some users have one and some the other.

I'm using one of the stable 1.0 releases for 184 accounts on Gentoo Linux on Sparc. I too am seeing the message header/body mismatch in Thunderbird. Is the index file handling sufficiently robust against surprises that I can delete the dovecot index files every night out from under the logged-in imap sessions? Brian

[Dovecot] pop vs. imap inconsistancy
by jeff sacksteder 08 May '05

08 May '05

I am converting from courier and have noticed change in behaviour with Dovecot. I use maildirs with squirrelmail connecting by imap as well as a POP3 client. Courier would set the 'mail status-read' flag for any message which was downloaded with the POP3 interface. Dovecot apparently does not. Is this a bug or intended behaviour? If it is intentional, can it be changed with the config file?

Hi: I'm running dovecot on a Fedora 3 box and would like to be able to make a TLS connection to it with my Pegasus Mail program running on my Winblows machine. Does anybody know if it is possible? If it is I could really use some help configuring my dovecot. I have tried for several days but I really don't know what I'm doing and need a direction to start. Thanks, -- Knute Johnson Molon Labe...

[Dovecot] Multiple Logins - Single Mail Account
by Net Cerebrum 04 May '05

04 May '05

I have a mail account which needs to be accessed by 4-5 people simultaneously through IMAP. As of now I have configured it on the respective clients using the same username and password so we have multiple people accessing the same account through their mail clients simultaneously and it is working flawlessly. Is this alright or can it lead to some problems or corruption of data later ? What is the best way to allow multiple people to access a single mailbox for read as well as write operations ? Thanks,

[Dovecot] Error in rename uidlist while fetching through pop3

My dovecot server seems to randomly begin giving errors to pop3 users who try to fetch their email. Once this begins, they see no more new mail, though the mail is in cur. Running: dovecot-stable 20050501, Mac OS X 10.3.9 Log entries like this: May 2 19:35:18 caddy dovecot: pop3-login: Login: kim [24.22.16.169] May 2 19:35:18 caddy dovecot: POP3(kim): rename(/Users/kim/Maildir/ dovecot-uidlist.lock, /Users/kim/Maildir/dovecot-uidlist) failed: Input/output error May 2 19:35:18 caddy dovecot: POP3(kim): file_dotlock_replace(/Users/ kim/Maildir/dovecot-uidlist) failed: Input/output error Is this a known problem, and/or is there a known way to recover from such a situation?

[Dovecot] How to try dovecot-lda
by Joakim Verona 02 May '05

02 May '05

Hello, I'm interested in trying the dovecot-lda with sieve support. What would be the proper way to test it? I'm currently using a Fedore core 2 server, with spamassassin and procmail. To get the same effect with dovecot-lda, would I put a line like this in my .forward? spamassassin|dovecot-lda I'm just guessing, so please correct me if im wrong. Im thinking of setting up a separate mail account and copy my mail there to test the ported procmail to sieve recipies also. -- Joakim Verona www.verona.se

[Dovecot] disabling indexes?
by Marten Lehmann 02 May '05

02 May '05

Hello, I recently had the problem, that an index was corrupt. Thus, messages haven't been listed (talking about POP3), but still remained in the filesystem. As there is no SEARCH-command in POP3, dovecot didn't notice that the index is corrupt and didn't rebuild it. The problem is, that a user can't delete messages through POP3 which aren't listed by dovecot. If the maildir size increases, the arrival of new messages will be blocked because the mailbox is full. And the user has no chance to delete it. Regards Marten

[Dovecot] Blank lines in mailboxes
by Jakob Curdes 30 Apr '05

30 Apr '05

Hello, we use dovecot on a regular basis. Sometimes I end up with a user telling me he does not get mail. When I look after the problem, I always find leading blank lines in the mbox file. We are using postfix with dovecot and amavisd as spam scanner. Amavisd never accesses the mbox files directly so this can be ruled out. I suspected procmail but now it happened also with accounts where no procmail is active. I found only a list thread where this happened always, i.e. it was a configuration error. (Meaning the mailbox was correct but dovecot would not read it). Here ist is only occasionally and therefore hard to track . Does anybody have the same problem or has hints to a solution ? We are running postfix 2.1.4 and dc 0.99.10.6 ; just now I am upgrading to pf 2.2.2. and dc 0.99.14. Yours, Jakob Curdes

[Dovecot] Fresh Dovecot Install
by GPL 29 Apr '05

29 Apr '05

Working on an RH9 box. Did not use yum. Downloaded the "dovecot-stable-latest.tar.gz". Uncompressed it, downloaded and installed gcc. Ran the following: ./configure make sudo make install Seemed to have done its thing. I'll admit I am not well versed in using "make" or compiling anything. When I install I usually use yum on fedora machines. This one being an RH9 machine I have plugged yum into the fedora legacy project and it did not let me install dovecot via yum. So I opted for this route. Regardless, if I run 'which dovecot' I see "/usr/local/sbin/dovecot" However now I do not seem to be able to see it run. I get nothing when I: rpm -qa | grep dovecot ps aux | grep dovecot service dovecot status SO AM HAVE MISSED SOMETHING! Is there another script I need to run? Suggestions welcome. Thanks, George

[Dovecot] dovecot 0.99.xx to 1.0-stable how-to?
by Rich West 28 Apr '05

28 Apr '05

I realize that there have been some big changes in features and configuration file settings between 0.99.xx and 1.0-stable, so when I went to perform an upgrade on our testing server, I carefully combed through the configuration files and matched up everything I could. I fired up dovecot-1.0-stable and was pleased to see that it was happily running. I attempted to connect to it, and discovered that it wasn't listening to any ports.. then I realized that the app had crashed due to a typo in the config file (oops). Fixed that, started it up, and it was happily running and listening. However, it wouldn't authenticate any users.. Backing down to the 0.99.14 version that we had installed allowed for authentication (against ldap) to work just fine.. Is there anything that I should be looking for within the dovecot-1.0-stable that is dramatically different in regards to user authentication? -Rich

I don't know enough to say either way. Maybe I'll take a closer look after I've finished delving into Sun's RBAC. As for the code changes, from memory the UID checking stuff is all in the one place ( in 0.99.14 it seems to be src/lib/restrict-access.c ). I'm not sure about 1.0... we'll move to that when we can have custom flags :) -- Curtis

[Dovecot] cutting everything after @
by Juraj Bednar 27 Apr '05

27 Apr '05

Hello, I am migrating one server to dovecot. The only problem is, that users have logins with @domain as part of their user name. I want to use pam auth (for other reasons, if only for dovecot, I would use mysql, but I need the same password db to be used for other services, like samba). Is there a way to allow this type of login? Just cut everything beginning with @. I can change the source code, but then I don't get nice automatic upgrades. Or can this be done easily with PAM? Thanks, Juraj.

[Dovecot] Shared mailboxes and accessing MailDir not through IMAP
by Steffen Kaiser 27 Apr '05

27 Apr '05

Hello, I'm testing Dovecot that is part of Debian/sarge (v0.99.14-1). So far so good. I have migrated some mailboxes for testing with success and seems that everything works fine. One thing I do not figure out is, what to do about shared mailboxes, which are the very reason of searching for an alternative IMAP server, The Wiki states that there is some sort of shared mailboxes, based upon symlinks. Well, but since which version actually?? The Changelog stops at 2003-11-08 21:12 ? What I need is a mailbox (maildir) for a contact address (not a real shared mailbox, but several users shall be able to read a mail and delete it after processing). For this, one needs write permission to the mails therein only, the MDA takes care of to make the mails readable for the group. It would be good to see, if somebody had answered a mail already, but that's not required. What I tried is this: I setup all Unix-permissions of the folders (. cur new tmp: u=rwx,g=srwx) and their parents (u=rwx,g=x). Then I placed a symlink into the maildir of all users. Each user caches the INDEXes into an individual /var/ directory, not in the maildirs themselves. (BTW: I wonder why I need to give the group write permission to the base directory '.'). The mailbox shows up and is read-write. Now I wonder, what impact I'm to expect here? Esp. "The only problem is that currently everyone's message flags would be shared as well." (quote from a message of a thread taken from the Wiki) Then there is http://dovecot.org/pipermail/dovecot/2003-March/001113.html the third item will apply to my situation, I guess. MailDir is (sort of) expected to be read by mutt directly, for instance. Because the mailboxes are located within the users home directories, some of them do this. Do this item mean that Dovecot is NOT expecting that mails are deleted in any other way than through itself? Otherwise Dovecot would find a change in the mailbox and rebuilt the index file regardless whether the change had been originated by another IMAP client or by directly manipulating the maildir. Bye, -- Steffen Kaiser

[Dovecot] local users + virtual domains
by Micha Silver 27 Apr '05

27 Apr '05

I'm redesigning our mail server which holds several hundred mailboxes - most are local system users and some are virtual domains that we host. I understand that the 1.0x stable release allows for multiple auth mechinisms, so that I could use both PAM for local users and a passwd-file for the virtuals. If I want to stick with 0.99x can I mix and match in a single passwd-file the username/passwd for both local and virtual users? In dovecot.conf I'd have something like: default_mail_env = maildir:%h/Maildir auth-userdb = /etc/dovecot/passwd-file auth-passdb = /etc/dovecot/passwd-file then in passwd-file I'd enter: # local users localuser1:<passwd>:501:501::::: localuser2:<passwd>:502:502::::: ... #virtual domains virt1(a)example1.com:<passwd>:5001:5001::/var/vmail/%d/%u:/bin/false::INBOX=/var/vmail/%d/%u/Maildir postmaster(a)example1.com:<passwd>:5001:5001::/var/vmail/%d/%u:/bin/false::INBOX=/var/vmail/%d/%u/Maildir virt1(a)example2.com:<passwd>:5001:5001::/var/vmail/%d/%u:/bin/false::INBOX=/var/vmail/%d/%u/Maildir postmaster(a)example2.com:<passwd>:5001:5001::/var/vmail/%d/%u:/bin/false::INBOX=/var/vmail/%d/%u/Maildir ...
