[Dovecot] Sanity checking on dovecot
by Jon Callas 26 Apr '06

26 Apr '06

I'm setting up a new server. I have a couple of dozen users, and several domains. I've set up Postfix as my MTA, and it's dropping things into maildirs. Now I want to get Dovecot to work for POP/IMAP. (Getting SMTP AUTH to work is also on the agenda, but slightly tangential.) Postfix is putting things into /var/mail/vhosts, an example line in my vmailbox file is: test(a)callas.org callas.org/test/ Dovecot is installed via darwinports. (Oh, yeah, this server is an Intel dual-core Mac Mini running OS X 10.4 -- *not* OSX Server.) So I need to figure out how to get dovecot to authenticate in my users. From reading <http://wiki.dovecot.org/VirtualUsers> and <http:// wiki.dovecot.org/Authentication> it will be easiest for me to set up a passwd-file authentication. So I would make some file somewhere in passwd-file format. As an example, I might set up "test(a)callas.org" as: test@callas.org:{plain}pass:1000:1000:Test User:<I think no home dir is needed>::mail=maildir:/var/mail/vhosts/callas.org/test/ Is this reasonable? Is there something easier that I'm missing? Jon

[Dovecot] Plan/Status of MBX support?
by Jiaying Xu 25 Apr '06

25 Apr '06

Hi, All, I've been happy user of dovocot as far. It is easy to configure, reliable and secure. Hat off to all developers who make this possible! I know dovecot is on the mailbox format front, it supports both mbox and maildir format well, and is developing and experimenting a new flexible format, dbox. But is there any plan to add mbx (i.e., indexed mbox format) support, to complete the set? There is some circumstance that mbox format is chosen over the mordern maildir format, For example in our situation, we receive many, many small messages and it would be expensive to create so many files with maildir. And we do a lot of searching - again a single mbox is faster in searching. Now the problem is, we have to use the tranditional mbox format with dovecot, as it does not support indexed mbox format, which makes deleting messages costly. Also the long-time file locking (due to the slow operation on the dovecot side) causes our MTA (exim, by the way) holds a huge queue. That drives up the system load to mad (load average above 500 is not unusual in our case). If dovecot support index mbox format, we be in the havean! But is there a plan to add this support in the near future? Thanks, JY

[Dovecot] Test migration (IMAP copy) and INTERNALDATE?
by Apps Lists 25 Apr '06

25 Apr '06

We're trying some migration tests ... from CommuniGate to Dovecot. The migration program does an APPEND into the new mailbox: src>: a0 FETCH 2900 (FLAGS INTERNALDATE RFC822.PEEK) src<: * 2900 FETCH (FLAGS (\Seen) INTERNALDATE "29-Aug-2005 18:36:54 +0000" RFC822 {1194157} src<: ) dst>: bAPP APPEND "INBOX" (\Seen) "29-Aug-2005 18:36:54 +0000" {1194157} dst<: + OK It appears to be trying to set the message date... in this example, to 29 Aug 2005. Dovecot seems to be ignoring it. Am I doing something wrong, or does Dovecot not allow this? Steve

[Dovecot] Dovecot LDA with sendmail/Mailscanner
by Gerhard Wiesinger 24 Apr '06

24 Apr '06

Hello! I'm running dovecot in a sendmail/Mailscanner/procmail/mbox environment. I want to use dovecot lda because index files aren't updated when using sendmail as lda. Has someone this combination running and some configuration hints so that sendmail, Mailscanner and procmail ist working well. Does procmail work with lda, too? Thank you for the answer. Ciao, Gerhard

[Dovecot] maildir memory usage
by lenny＠edpausa.com 24 Apr '06

24 Apr '06

Dovecot beta 5 + dovecot lda, solaris 9 sparc. Dovecot seems to use a lot of memory with large Maildir folders, ( 300-500 mb folder - 100-200 mb process), something I never noticed with similarly large mboxes. Is that expected behavior or are my observations incorrect.

[Dovecot] Just setup Dovecot and having a small problem.
by Tom Ray 24 Apr '06

24 Apr '06

I've just installed Dovecot and am running into a bit of a problem with it. I'm using virtual email accounts and everything seems to be working up to a certain point. Let me break down how the server is setup. Each domain belongs under the directory /mail so it's path is basically: /mail/domain.tld. Within each domain directory there are two sub-directories etc and mail. Under /mail/domain.tld/etc I have two files setup aliases and passwd, the aliases file handles all mail aliasing for that domain and the passwd file holds the users account name and password. The password file has the accounts stored in the following format: user@domain.tld:(encrypted password):500:500:Virtual User:/mail/domain.tld/mail/user:/dev/null The password enctryption is basically htpasswd() style encryption. Now the problem I'm having is I keep getting authentication errors when I try to login via POP3 (I'm testing via command line so I do `telnet localhost 110`). At first I had only auth_debug_passwords=yes set and I was seeing this in the log file: Apr 23 18:54:19 www dovecot: auth(default): client in: AUTH^I1^IPLAIN^Iservice=POP3^Isecured^Ilip= 127.0.0.1^Irip=127.0.0.1^Iresp=AHRvbUBkZXRyb2l0b25saW5lLmNvbQBuZXdiZXJn Apr 23 18:54:19 www dovecot: auth(default): pam(user(a)domain.tld,127.0.0.1): pam_authenticate() failed: Authentication failure Apr 23 18:54:19 www dovecot: auth(default): passwd-file /mail/domain.tld/etc/passwd: Read 1 users Apr 23 18:54:19 www dovecot: auth(default): passwd-file(user(a)domain.tld, 127.0.0.1): unknown user Apr 23 18:54:20 www dovecot: auth(default): client out: FAIL^I1^Iuser= user(a)domain.tld So I can see it's reading the proper password file but it claims that user doesn't exist, however, that user does exist. When I turn on auth_verbose=yes and I'm still seeing the same errors in the log file. Can someone tell me what I'm missing here? I'm really on a time crunch with this, our mail server died friday morning and it's been put on me to fix it. They insist I use UW IMAP but I can't get it to work with the vitrtual users like the previous guy did. I've used Dovecot before but it's been two years and I can't remember how I got everything working before. They want things back to normal by Monday morning (tomorrow) so now I'm a bit stressed since I've lost most my weekend rebuilding the server and users. Any help would be appreciated. I thought I had this setup just right but I just can't get passed it telling me the user doesn't exsist.

[Dovecot] PINE + dovecot
by Richard Randriatoamanana 24 Apr '06

24 Apr '06

Hi list, I have installed dovecot on fedora4 and I migrated courier-imap to dovecot with instructions given on the site. everthing works fine for thunderbird, horde, evolution and mail/macosx.. but i have some pbs with pine because it doesnt read .subscriptions and directories aren't seen as it should be seen like in the .subscription. maybe i should reconfigure the .pinerc correctly, but what should I put in place then? does anyone have a .pinerc template that reads like other mail browsers with dovecot? Thanks in advance Cheers. Richard

When I have it set to disable_plaintext_auth = no I can get POP working but IMAP throws back errors. Any other thoughts?

[Dovecot] Solved problem with index corruption (new mail not seen)
by Tom Alsberg 24 Apr '06

24 Apr '06

Having had many problems in the past with IDLE not working, new messages not being seen from Thunderbird, and sometimes garbage seen as part of mailboxes, I eventually added some workaround/sanity check patch to the imap_sync_deinit code to reread the offsets from the index and that solved the problem. Now with beta7 (I've previously used beta2), this seems not to be necessary anymore. I installed vanilla beta7 and couldn't reproduce the problem in any way! I'm not sure what has changed there, and haven't yet checked if I see anything relevant, so this is just to let you know, and ask - any idea which change could have caused this. Happily I will soon be going on with working around other issues I have here, and start bugging you in the list again.
