[Dovecot] Thinking about switching from courier-imap to Dovecot: 2 simple questions
by kadafax 23 Dec '05

23 Dec '05

Hi, I'm using RHEL4 and since the dovecot RPM is present in the main repository, I'm thinking about switching from courier-imap (with whom I've got trouble to update) to Dovecot. Here are two questions about Dovecot (google didn't answer me): 1. Is it possible for dovecot to use the bind mecanism against ldap for authentification purpose. My main concern is to avoid the clear-text password in the dovecot-ldap.conf file. With courier-imap, the process simply bind to the ldap tree with the users's supplied login/password. No need for a special authentification purpose user. 2. Does imap's dovecot implementation support folders imbrication (more than one level folders) ? Thanks, kfx.

[Dovecot] Dovecot & pam_mkhomedir
by Stroller 22 Dec '05

22 Dec '05

Hi there, Does anyone have Dovecot working correctly with pam_mkhomedir, please? I seem to be going through quite a number of IMAP servers this week, trying to find one that will not only authenticate against a Windows domain but which will also create home directories for users the first time they log in. I'm using winbind to do the authentication & that seems to be doing the trick in the first instance - if I log in using Squirrelmail I see entries written to the system log saying: Dec 16 11:58:35 baby pam_winbind[9319]: user 'ned' granted access I have set Dovecot to log to /var/log/mail and in that I see only three entries saying: imap-login: Dec 16 11:58:36 Info: Login: ned [127.0.0.1] But Squirrelmail gives: ERROR: Could not complete request. Query: SELECT "INBOX" Reason Given: /etc/pam.d/imap says: #%PAM-1.0 auth required /lib/security/pam_winbind.so account required /lib/security/pam_winbind.so session required /lib/security/pam_mkhomedir.so skel=/etc/skel umask=0022 If I use the same configuration for SSH then the user's home directory is created upon authenticaton, but not with Dovecot. I chose to try Dovecot because I understood it handled PAM session wossisnames, which Courier-IMAP doesn't. My dovecot.conf is attached - I'm wondering if the problem could be with the "auth_userdb" setting, but `getent passwd` does show an entry for the user: # grep ned /etc/passwd # getent passwd | grep ned ned:x:10012:10000:Ned Nedbody:/home/DOMAIN/ned:/bin/false # Many thanks in advance for any advice or suggestions - I'd really like to understand what's going on here. I believe I can authenticate against the domain using LDAP / Active Directory, but since I don't know if that'll help I'd rather not go that route yet. If I first try to log in using ssh with pam_mkhomedir enabled then the users' home directory is created successfully & I can subsequently log on in Squirrelmail. But it's important to me that I shouldn't have to create users' home dirs for them - I should be able to add them on the Windows domain controller & just tell them to log in to their email - the home dir on the mailserver should be created automagically when they authenticate against the domain.

[Dovecot] Authentication trouble.

[Dovecot] dovecot -CVS and epoll and cvs not building
by Reuben Farrelly 22 Dec '05

22 Dec '05

Hi, After reviewing my dovecot ./configure options I thought I'd give --with-ioloop=epoll a go again (as opposed to just using =poll) but I'm seeing some errors appearing in the maillog that aren't there with standard poll: Dec 23 02:34:47 tornado dovecot: imap-login: Login: user=<reuben>, auth-method=plain, remote=220.237.24.149, TLS Dec 23 02:34:48 tornado dovecot: imap-login: io_loop_handle_add: epoll_ctl(3, 9): No such file or directory Dec 23 02:34:48 tornado dovecot: child 16524 (login) returned error 89 They're appearing fairly frequently, ie within a few mins of starting up and then the message won't go away until the client is restarted. So it's easy to reproduce but I'm not sure how to go about debugging it. Can anyone help with this? It's a very recent Linux-2.6 system so epoll support should not be an issue. Additionally -CVS won't compile for me right now, it bails out when compiling the 'quota' plugin. Workaround is to manually edit the dovecot/src/plugins/Makefile and not build this plugin.. Timo - is there a file/commit missing from -CVS at the moment for this plugin? I see no other reference anywhere for dqb_curblocks in the code. gcc -DHAVE_CONFIG_H -I. -I. -I../../.. -I../../../src/lib -I../../../src/lib-dict -I../../../src/lib-mail -I../../../src/lib-storage -std=gnu99 -g -O2 -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -I/usr/kerberos/include -MT quota-fs.lo -MD -MP -MF .deps/quota-fs.Tpo -c quota-fs.c -fPIC -DPIC -o .libs/quota-fs.o quota-fs.c: In function 'fs_quota_get_resource': quota-fs.c:208: error: 'struct dqblk' has no member named 'dqb_curblocks' make[1]: *** [quota-fs.lo] Error 1 reuben

[Dovecot] Migrating from mbox to maildir, which converter is compatible with dovecot
by Oliver Schulze L. 22 Dec '05

22 Dec '05

Hi, I'm testing/debuging the migration from mbox to maildir in a mailserver running Dovecot 1.0alpha5. I migrated all 472715 emails(in a test server) and later noted that dovecot could not get the same flags/status of the emails as in the mbox. I was using perfect_maildir.pl and I think its not dovecot fault. Seems to me that perfect_maildir.pl convert the emails in a way that dovecot could not understand completelly. So, my cuestion is, which mbox to maildir converter can I use that is compatible with dovecot 1.0alpha5 ? Thanks Oliver -- Oliver Schulze L. <oliver(a)samera.com.py>

[Dovecot] mailbox from ldap and indexes
by Stian Jordet 21 Dec '05

21 Dec '05

Hi, because of quota, I would like to have indexes on another filesystem then user's maildir. This I can do with "default_mail_env= maildir:/% h/Maildir:INDEX=/var/indexes/%u" or something. But when I get the users mailbox location from ldap, there is no way to set the index? I guess I can make the ldap entry contain the INDEX as well, but I would like to use the ldap entry in the exim conf as well, to tell exim where to write the mails... Is there a way I haven't thought of yet? I have this in dovecot-ldap.conf now: user_attrs = uid,homeDirectory,mailbox,uid,uidNumber,gidNumber If I could do something like: user_attrs = uid,..,"maildir:" . mailbox . ":INDEX=var/indexes/%u",... that would have been awesome. Best regards, Stian

[Dovecot] Another "Too many files open" post

I'm running Solaris 9 Sparc with Dovecot alpha 5 and using maildir format.. I noticed in the log file the following error: dovecot: Dec 20 15:54:18 Error: imap(xxxxxxxx): open(/export/home/xxxxxxxx/mail/.Sent Messages/cur/1135013649.002916.mbox:2,Sab) failed: Too many open files I called the guy and asked him what he was doing... synching his folders.

Also, on Jeff Earickson's post, I looked at my dovecot.conf settings and they're basically default which means everything in the "Login processes" section is commented out. I have 10 users on this system and will hold off migrating any more until I can resolve this problem. By the way, my "ulimit -a" shows "open files" at 256 which seems low. # ulimit -a core file size (blocks) 0 data seg size (kbytes) unlimited file size (blocks) unlimited open files 256 pipe size (512 bytes) 10 stack size (kbytes) 8192 cpu time (seconds) unlimited max user processes 29995 virtual memory (kbytes) unlimited Any advice would be appreciated.

[Dovecot] 1.0 alpha5: Plugin woes: quota/trash
by Jan-Piet Mens 21 Dec '05

21 Dec '05

Hello, I'm running Dovecot v1.0.alpha5 and I'm trying to get the quota plugins to work. I've enabled modules in dovecot.conf, but when the IMAP connection is opened, the log shows undefined symbols. : Loading modules from directory: /usr/local/lib/dovecot/imap : dlopen(/usr/local/lib/dovecot/imap/libtrash_plugin.so) failed: /usr/local/lib/dovecot/imap/libtrash_plugin.so: undefined symbol: quota : dlopen(/usr/local/lib/dovecot/imap/libimap_quota_plugin.so) failed: /usr/local/lib/dovecot/imap/libimap_quota_plugin.so: undefined symbol: quota : dlopen(/usr/local/lib/dovecot/imap/libquota_plugin.so) failed: /usr/local/lib/dovecot/imap/libquota_plugin.so: undefined symbol: dict_transaction_commit The source shows that the modules are read by reading the module directory and loading each of the found .so files. Supposing that the ordering of the files in the directory is wrong, I've even recreated the module directory manually, copying the libs into it in different orders; no change. It seems to me as though there are cross-dependencies in the shared libs that cannot be resolved. Has anybody found it to work or could anyone give me a hint on how to get it working? Thanks & regards, -JP

[Dovecot] messages_count too large (2578 > 2566) Help!
by Rob Frohne 20 Dec '05

20 Dec '05

Hi, I'm having trouble as of about noon today. I noticed I wasn't getting any new messages in Thunderbird. I restarted it and still nothing. I looked at the log, and found nothing from dovecot for a long time (since perhaps noon today). I restarted dovecot, but still it didn't get me new mail. I finally removed dovecot.* in my Maildir folder and restarted dovecot. I'm using 1.0alpha4.

[Dovecot] Auto-expunge
by John Newman 20 Dec '05

20 Dec '05

Hi, For some time we've been intermittently experiencing a problem whereby dovecot often automatically expunges "deleted" messages. This has happened across several mailboxes. The problem is proving difficult to isolate as it's seemingly non-deterministic in nature. One commonality, however, is that the "auto-expunge" seems to occur with greater frequency on mailboxes with a larger of deleted messages. First off, does this sound any alarm bells for anybody else? Perhaps others have encountered this in the past? I've trolled the mailing list (and web) but cannot find any references to this occurring elsewhere. Additional Information: We have experienced this "bug" in 1.0-alpha3 and alpha4. Underlying dovecot we have a maildir, populated via Perl's Mail::Box::Maildir module. Many thanks for any assistance that can be offered. John.

If its too hard for them to setup the pop3 catch all, we can probably put some mapping in place to smtp froward mail to their server. This is more complex on our part so would prefer not to do it that way, but its an option and will require not setup on their part other than make sure their server does not accept mail for anyone other than our server. dovecot-request(a)dovecot.org wrote: > Send dovecot mailing list submissions to > dovecot(a)dovecot.org > > To subscribe or unsubscribe via the World Wide Web, visit > http://dovecot.org/cgi-bin/mailman/listinfo/dovecot > or, via email, send a message with subject or body 'help' to > dovecot-request(a)dovecot.org > > You can reach the person managing the list at > dovecot-owner(a)dovecot.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of dovecot digest..." > > > Today's Topics: > > 1.

[Dovecot] Two-phase delete/expunge ?
by Jan-Piet Mens 16 Dec '05

16 Dec '05

Is it possible to have messages which have been marked for deletion or which are to be expunged, moved into a "secret" directory on the IMAP server? The IMAP client would consider the message as deleted, but an administrator could easily restore single messages (without having to retrieve tapes) by moving the message back into inbox. I understand there are patches floating around somewhere enabling that for Cyrus, but I'd love to see Dovecot do that as well. Is anyone aware of such functionality? Thanks, -JP

But when my users are in China, sometimes the following problem occured. Sometimes the user can not download mails, after that all connections attempt to server(e.g http/ssh) failed. the user has to close OutLook, and wait for about 10 minutes, then access the webmail to read mail. Maybe the POP NG is due to the network , but what is the possible reason of 10-minute other connection NG? Is there any solution? Because users in China share the same outside IP, when one user occures POP NG, all users occures server access NG, that is a big puzzle. Thanks in advance. Best regards,

[Dovecot] Patch: ioloop using kqueue/kevent for FreeBSD
by Vaclav Haisman 16 Dec '05

16 Dec '05

Hi, I would like to submit the attached patch. It implements IO loop using FreeBSD's kqueue/kevent syscalls. It is based on snapshot of CVS HEAD as of 2005-12-12. I could only give it limited testing on FreeBSD 5.4 but it works fine so far. Vaclav Haisman

[Dovecot] 1.0alpha5 released
by Timo Sirainen 16 Dec '05

16 Dec '05

We have now some new big features: - Beginnings of dbox mailbox format. It should work, but if you happen to delete/break index files, the mails aren't found again. So really not a good idea to use it for more than testing. - GSSAPI (Kerberos 5) support by Jelmer Vernooij with some fixes by pod(a)herald.ox.ac.uk - Added dictionary API to Dovecot, similar to what Postfix has. It can be used for getting/setting key=value pairs, which can be useful for many different purposes. For example it could be used to store mailbox metadata for ANNOTATEMORE extension. Implemented SQL backend for it. In future there should be berkeley DB backend at least. Also there could be some kind of proxy backend which would use UNIX socket to connect to dictionary server doing the actual work. This way each imap/lda process wouldn't have to connect to SQL server themself. - Quota plugin is now included. We also have now dictionary based quota support, which means the quota limits and values can be stored in SQL. However I haven't actually tested these changes yet, so there's a good chance the quota plugin doesn't actually work at all. - Created a new trash plugin which works only together with quota plugin. The point of it is to expunge mails from a list of configurable mailboxes whenever saving new mails would cause the account to go over quota. The oldest mails are expunged first, and only as many mails are expunged as is needed to save the new mail. For configuration it first looks up for ~/.dovecot.trash.conf, and then fallbacks to /etc/dovecot-trash.conf. The file format is "<priority> <mailbox name>". It's possible to have multiple mailboxes with same priority. Lower number = higher priority. This plugin is also currently untested. The plugins are currently installed as shared libraries to plugin directory. At some point I'll add a configure option to select which plugins to compile directly into binaries. Possibly even do it by default for some plugins (quota). And smaller new features: - If LDAP lookup fails because connection gets closed, try retrying it again after reconnect. This is however untested, hopefully didn't break LDAP code completely.. - %w variable in dovecot-auth contains password. Can be used to do eg.: password_query = select null as password from users where userid = '%u' and password = password('%w') - syslog_facility setting And fixes: - auth_cache was quite broken - adding keywords caused sometimes assert-crash - If login_greeting_capability = yes we could have sent the capability before dovecot-auth returned what auth mechanisms were available, forcing clients to use plaintext authentication - Lots of mbox fixes again.. - userdb prefetch wasn't supposed to be uncommented in dovecot-example.conf in alpha4. Comment it out if you don't need it. - Don't crash with "out of memory" in 64bit systems - IDLE command might have crashed when finishing itself if there were lots of external changes - pop3_reuse_xuidl setting wasn't actually working

[Dovecot] Logging IMAP deletions

16 Dec '05

I'm using dovecot-1.0.alpha5 and I'd like to be able to log the fact that a message has been deleted (or marked for deletion) in order to prove to end-users that they actually deleted a message. Is that possible? -JP

[Dovecot] messages_count too large (1121 > 1115)
by Moritz Willers 16 Dec '05

16 Dec '05

I've seen this was mentioned before but remains unsolved. I upgraded Dovecot from 0.99 to v1.0.alpha4 yesterday and it rendered my inbox inaccessible: Dec 15 00:09:07 sand dovecot: imap(willers): Corrupted index file /home/willers/mail/.imap/INBOX/dovecot.index: messages_count too large (1121 > 1115) I've since moved that inbox away so I can view my new mail again. The error has moved with the mbox file: Dec 15 00:27:41 sand dovecot: imap(willers): Corrupted index file /home/willers/mail/old-inbox/.imap/200407-200512/dovecot.index: messages_count too large (1121 > 1115) Dec 15 00:27:41 sand dovecot: child 83886 (imap) killed with signal 11 This is on FreeBSD 4.8 (yes, yes ... but: "up 687 days" which is quite nice) all running on local disk. So earlier suspicions about NFS or MacOS X are out of the window. One day I'll move move from mbox to dir format and the problem will go away, in the meanwhile, I thought it would be good to resolve this issue. Let me know how I can help to get to the bottom of this. - mo

[Dovecot] Best way to upgrade from 1.0a4 to 1.0a5
by Cliff Hayes 16 Dec '05

Hello all, I have 1.0 Alpha 4. Is it better to shut down sendmail, uninstall dovecot 1.0a4 then install 1.0a5, or just install 1.0a5 over the top of 1.0a4? Thanks, Cliff

[Dovecot] Variable '%r' doesn't transfomr in Postgres query
by Sebastjan Trepca 15 Dec '05

15 Dec '05

Hi, i'm using postgres for authorization. When I switched from a4 to a5 authorization stoped working. Query in conf file for postgres looks like this: password_query = select password from auth('%u','%r'); But in logs, the transformed query looks like this: Performing query: select password from auth('test','%r'); Looks like you don't transform that remote IP parameter?

[Dovecot] writing an MDA, help me avoid corrupted indexes
by Lee Howard 15 Dec '05

15 Dec '05

Hello. First, I want to thank those responsible for Dovecot IMAP as it was a real treat to implement in comparison to my mostly-failed attempts with Cyrus. The passwd-file authentication was exactly what I needed as I really didn't want to have to deal with PAM or LDAP but where I am setting up a server with virtual accounts. I'm using Postfix as an MTA, and it quite handily passes the mail off to SpamAssassin. From there I need an MDA to dump any mails detected as spam into a common spam folder, discard any mails with viruses (antivir) and send a notification to me, and then drop good mail into the appropriate maildir directory for the virtual users to get via both POP3 and IMAP. I could conceivably use procmail to do that MDA, and I've done similar things with procmail in the past, but my growing experience with procmail indicates that procmail is too ferocious for what simple work I need done, and too difficult to make work right in a virtual-user environment. So I've written my own little MDA with a few lines of shell that will take the mail from Postfix+SpamAssassin and ultimately deposit mails in the maildirs. So far so good, except that I keep seeing corrupt indexes... probably because I'm not touching the indexes at all with the MDA. My guess is that in order for the MDA to properly deal with maildir it needs to adjust the indexes after depositing new mail. Okay. So can someone either give me a pointer to the proper documentation on this, including the index file formats, or perhaps just explain it to me? Maybe I'm missing a larger picture of maildir handling? I've glanced through http://www.dovecot.org/doc/index.txt but I notice that the index files are not ASCII, so I'm not sure where to start at understanding that documentation. Any and all help would be appreciated. Thanks, Lee.

[Dovecot] How to serve two "inboxes" via imap
by Roderick Johnstone 15 Dec '05

15 Dec '05

Hi In our setup we have mail delivered to /var/spool/mail/<username>. Many users like thunderbird as their MUA and we typically have thunderbird set up to read mail using a movemail account with the local mail directory set to ~/mail so that the mail can be read easily by pine as well. So, when a user clicks the "Get Mail" button in Thunderbird, mail is moved from /var/spool/mail/<username> to ~/mail/Inbox. Although I can serve other folders from ~/mail my imap clients don't see ~/mail/Inbox, they see just /var/spool/mail/<username> as INBOX. Can anyone advise please how to make the ~/mail/Inbox available as well via imap using dovecot (currently using 1.0-alpha5). We currently use default_mail_env = mbox:~/mail/:INBOX=/var/spool/mail/%u Many thanks Roderick Johnstone

[Dovecot] checkpassword authentication
by Florian Füessl 14 Dec '05

14 Dec '05

Hi, does anyone already use the checkpassword authentication scheme? I have not found any description how I have to configure dovecot in order to work together with qmails checkpassword. Enabling passdb = checkpassword /bin/checkpassword in dovecot.conf starts /bin/checkpassword for every authentication request, but the result does not seem to matter for the authentication. Without enabling a userdb entry, dovecot claims not to be able to find out the uid, gid and home of the user, although checkpassword replies these values. Setting static values with "userdb = static uid=$fixed_mail_uid gid=$fixed_mail_gid home=/maildata/%d/%n" results in being every login successful, no matter if the checkpassword authentication is ok, or not. I'm using the latest dovecot nightly build from 22. Nov. 2005. - Florian

Hi, dovecot (1.0.alpha5) won't compile with inotify support because inotify.h can't be found. I'm running Linux 2.6.15-rc5 with headers from 2.6.12 (like most vendors). I've noticed that beagle and other inotify-enabled applications ships with an inotify.h. Could this be scheduled for alpha6? :-)

I'm trying to switch to imap from pop3, so I set up dovecot on my Slackware 10.2 mailserver. I'm very new to imap, so I figured my configuration was wrong. If our symptoms are the same, maybe our setup errors are as well. The problem... while Thunderbird and Outlook are OK, the Inbox doesn't show in Outlook Express. You can click on the Imap Folders button, select the Inbox, click on the "Go To" button and the Inbox will appear until you shut down Outlook Express. Next time you fire up OE, no Inbox. Other than that, it all works as expected. I haven't torture-tested the setup yet though, I wanted to set up one of each client and get the basics running before doing that. Are your symptoms similar? Here is my dovecot.conf less comments... ssl_cert_file = /etc/mail/certs/wally.cert.pem ssl_key_file = /etc/mail/certs/wally.key.pem first_valid_gid = 100 mail_extra_groups = "mail" namespace private { separator = / inbox = yes prefix = "#mbox/" location = mbox:/var/spool/mail/%u } namespace private { separator = / prefix = location = maildir:/data/imap/%u } protocol imap { imap_client_workarounds = outlook-idle } protocol pop3 { } auth_realms = "laframboise.net" auth default { mechanisms = plain passdb shadow { } userdb passwd { } userdb prefetch { } user = root }

[Dovecot] mailserver pop3-login: Disconnected
by Shawn Bishop 13 Dec '05

13 Dec '05

Good Day I am having the following serious problem. I am running CentOS 4.1 with dovecot 0.99.11. The users are using POP3 login to retrieve mail. For the last 2 days we have experienced the following problems. I have recreated all the users and reconfigured the dovecot,but the same problems occur. Please see attached /var/log/maillog messages It appears so users login whereas others cant.Eventually after about an hour none of the users can login.

[Dovecot] Case sensitive nightmare
by Erik Petersen 12 Dec '05

12 Dec '05

It took me 4 days to figure this out and I sure hope someone can help me solve it. My Setup: Postfix + MySQL + dovecot dovecot.conf: default_mail_env = maildir:/var/spool/vmail/%d/%n/Maildir password_query = SELECT password FROM mailbox WHERE username='%u' user_query = SELECT maildir, 108 AS uid, 108 AS gid FROM mailbox WHERE username='%u' The virtual host schema is postfix.admin compatible but I¹m not using it (phpMyAdmin is actually easier to use). When foo(a)domain.tld, abrand new account, logs in using an IMAP client (any client; squirrelmail, OE, tbird, Apple...) a maildir is created named domain.tld/foo/Maildir¹ and everything is good. Now I login as Foo(a)domain.tld and then as fOo(a)domain.tld and then as foO(a)domain.tld then so on for every case variation. Each of these accounts can login correctly, they are seen as being the same account by dovecot. On the other hand they are not seen as being the same mailbox! When I check my mail spool I see one maildir for every case variation (domain.tld/foo/Maildir, domain.tld/FOO/Maildir, etc.) It would seem to me that the queries above would fail for the different variations of the name but they don¹t seem to. Is dovecot converting %u to lower case for the query on the virtual users table but then using it unconverted when looking up the Mairdir for the account? If the username column has the value foo(a)domain.tld1 how does SELECT * FROM table WHERE username=¹FOO(a)domain.tld1 match the row? Also puzzling is that I select a column named maildir which has the path to the mailbox in it (using the correct case). Even if SELECT pigs fly¹ AS when WHERE FoO¹=¹foo¹ the maildir path for the account is being returned which is domain.tld/foo/Maildir¹ so how does domain.tld/FoO/Maildir¹ get created? This is both a pain in the nuts support nightmare but also a security problem (albeit fairly limited). An account named ³barneyrubble² could generate a significant number of maildir directories if you logged in with every variation thereof. Any assistance would be greatly appreciated. Thanks

[Dovecot] configuring squirrelmail with tls for both imap & smtp on FC3 with dovecot & postfix
by ankush grover 12 Dec '05

12 Dec '05

hey friends, I am trying to secure my mail server.I have enabled TLS support in postfix(version postfix-2.1.5), now I am trying to configure squirrelmail(version 1.4.4-1 rpm) for tls/ssl support.In config.php i have choosen use_imap_tls=true and use_smpt_tls=true. Moreover If I send any mail from squirrelmail there are no entries for ssl or tls in maillogs whereas If I send the mail through evolution I can see tls/ssl entries in maillogs. starting TLS engine Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: setting up TLS connection from [192.168.1.68] Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:before/accept initialization Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:error in SSLv2/v3 read client hello A Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:error in SSLv2/v3 read client hello B Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:SSLv3 read client hello A Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:SSLv3 write server hello A Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:SSLv3 write certificate A Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:SSLv3 write server done A Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:SSLv3 flush data Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:error in SSLv3 read client certificate A Dec 12 12:30:08 cluster1 last message repeated 2 times Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:SSLv3 read client key exchange A Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:error in SSLv3 read certificate verify A Dec 12 12:30:08 cluster1 last message repeated 3 times Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:SSLv3 read finished A Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:SSLv3 write change cipher spec A Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:SSLv3 write finished A Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:SSLv3 flush data Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: TLS connection established from [192.168.1.68]: SSLv3 with cipher RC4-MD5 (128/128 bits) But when I did the config.test for squirrelmail I got the below error Checking IMAP service....
