[Dovecot] Apple Mail cannot connect (1.0 beta3)
by Gregory K. Ruiz-Ade 03 Mar '06

03 Mar '06

I'm testing 1.0 beta3 on our mail server, and finding that Apple Mail seems unable to connect to it. I'm running the 1.0b3 on port 997 so we can test it in parallel to 0.91 to compare performance (so far, it's hella faster). I've ensured that the users testing are _not_ connecting in any way to the 0.91 version running on port 993. From the OS X client side (10.4.5 + latest patches), Apple Mail simply sits there and spins, and eventually times out. The error it gives is: ----- Alert There may be a problem with the mail server or network. Check the settings for account "UCSD" or try again. The server error encountered was: The connection to the server "csefast.ucsd.edu" on port 0 timed out. ----- I'm thinking, "port 0, WTF?" ... On the server, I get this out of the logs: ----- Mar 2 11:54:48 csefast dovecot: imap-login: Disconnected: Inactivity: rip=<client_ip_address>, lip=<server_ip_address>, TLS Mar 2 11:54:48 csefast dovecot: imap-login: SSL_accept() syscall failed: EOF [<client_ip_address>] ----- Apple Mail is configured to connect to port 997 and has "Use SSL" checked. I'm not getting anything else useful out of the Mac in terms of debugging info. Thunderbird seems to be working fine (all platforms). The configuration file in use is: ----- protocols = imaps ssl_cert_file = /usr/share/ssl/certs/<servername>_cert.pem ssl_key_file = /usr/share/ssl/private/<servername>_key.pem login_greeting = Dovecot ready. max_mail_processes = 2048 verbose_proctitle = yes verbose_ssl = yes first_valid_uid = 100 mail_debug = yes default_mail_env = mbox:~/:INBOX=/var/mail/%u mail_full_filesystem_access = yes mbox_write_locks = dotlock fcntl mbox_very_dirty_syncs = no protocol imap { ssl_listen = *:997 login_greeting_capability = yes } protocol pop3 { } auth_verbose = yes auth_debug = yes auth default { mechanisms = plain passdb pam { args = session=yes dovecot } userdb passwd { } user = root } ----- Any ideas?

[Dovecot] Thunderbird 1.5 and dovecot 1.0 beta 3 problem
by Peterg 03 Mar '06

03 Mar '06

My mailhosting provider has been testing dovecot 1.0 beta 3 as a proxy server and they asked the customers if they would like to test it out and report any issues. I am using Thunderbird 1.5 (IMAP) and have been with this mailhosting company for two months and have no issues at all with their current setup which uses Perdition as their proxy servers. The problem(s) I am encountered have been reported here a few times previously over the last couple of years but in searching I have not found any concrete solutions. When I first tested it out there was a continuous problem of a failure in saving a copy of an email to the sent folder although the message was sent. One of the staff of the mailhosting company noted this exact problem as well and believed the issue was Dovecot announcing different IMAP capabilities than the real backend IMAP servers (via the CAPABILITY command). This was supposedly fixed and initially there were no issues with the first set of test emails. However, in short order, this problem re-emerged and there would be sporadic failures to copy a message to the sent folder. Another issue would be that every now and then, when clicking on a folder in the left-hand pane (and no other activity going on with Thunderbird like downloading a new mail) Thunderbird would hourglass for 10-15 seconds as if it were trying to open a connection and was having difficulty. The maximum number of connections setup in Thunderbird is the default 5 and I am advised that this is the correct setting with their servers. Reducing the maximum number of connections does not appear to change matters in terms of avoiding these problems. Changing back to the current system (ie not using the test proxy server) both these issues disappeared. I have been in communication with the mailhosting provider as to my findings but it would be most appreciated if others here would perhaps have some insight into this matter. Peter

[Dovecot] maildir locking and 'racing'
by William Ross 02 Mar '06

02 Mar '06

hello Timo, list, quick error-message question. A few of the accounts on my main mailserver are failing to log in with errors like this: dovecot: Mar 02 19:33:35 Error: imap(user(a)example.com): maildir_file_do(/var/lib/vpopmail/domains/example.com/user/Maildir) racing if I log in by telnet everything is fine, and from the source it looks like the error happens when dovecot fails to get a lock on some important file or other. Could it be to do with concurrent connections? No idea. Has anyone seen this, and can you suggest a quick fix? I can't see any obvious difference between the accounts that work and those that don't :( nb. this is with vpopmail, and the Maildirs have just been moved over from another server that was also running the same version of dovecot. Some of the accounts do work. Perhaps it's just an obscure file permissions problem, or something? I'd be very glad of any suggestions. thank you, will

One of our servers running Dovecot 1.0.beta3 and dovecot-lda has failed to deliver a few messages and I can't figure out why.

[Dovecot] Maildir Quotas
by wink＠gettcomm.com 28 Feb '06

28 Feb '06

Hey guys, Does anyone have any ideas as to when this may be implemented? I'd love to be able to use dovecot, but without quota support, it just won't fit the bill. Is there any developer documentation as to what would be required to fully support maildir quotas as I'd be willing to help implement it assuming it's not going to take me weeks to become familiar enough with the codebase. Thanks

[Dovecot] using dovecot for postfix sasl

I have followed the Dovecot/Postfix/SASL howto, and modified the main.cf and dovecot.conf files, yet when trying to authenticate during a postfix SMTP session the log reports: "postfix/smtpd....warning: SASL authentication failure: Could not open db" Dovecot itself is authenticating IMAP logins correctly, and it is creating the auth file in the location specified under /var/spool/postfix/private. Why is postfix not able to get to the Dovecot auth mechanism? Thanks. Hugh

[Dovecot] Sorting order after mail move
by Václav Haisman 28 Feb '06

28 Feb '06

Hi, when I move some recent mail from some mbox folder into Maildir folder the moved email sorts as the first (on top) in the folder while it should be on the bottom with the rest of the recent emails in the folder. This happens only when moving from mbox folder to Maildir folder. I am not sure if it is really Dovecot bug or not but I suspect it could be so because it only happens in this one specific scenario.

[Dovecot] two possible inboxes, possible to check both?
by adcx＠server101.com 28 Feb '06

28 Feb '06

We're currently in the process of organising a migration from mbox to maildir mail storage on our server, and are hoping to phase this in gradually using dovecot's capabilities. Procmail has already been configured to deliver mail to either the existing mbox or to a new maildir for the user based on the (non)existence of a .converted file in their home directory. Where we are having problems is the pop3 retrieval side of things. Basically, we're chasing a setup where dovecot will first check to see if /mail/<first letter of username>/username exists (indicating that the account has had the .converted file created and new mail has since been delivered to that user in the new maildir format). If this directory does not exist, it should fallback to retrieving mail from the as-yet unconverted mbox, /var/mail/username. We've tried different combinations of namespaces and default_mail_env values to achieve this without success. One attempt which has come particularly close was: 1. Leaving /etc/dovecot.conf almost entirely default. The auto-detection ability of dovecot performs the following (output to /var/log/maillog): Feb 28 14:57:45 mouse dovecot: pop3(joe): maildir: access(/home/joe/Maildir, rwx): failed: No such file or directory Feb 28 14:57:45 mouse dovecot: pop3(joe): maildir: couldn't find root dir Feb 28 14:57:45 mouse dovecot: pop3(joe): mbox: root exists (/home/joe/mail) Feb 28 14:57:45 mouse dovecot: pop3(joe): mbox: INBOX exists (/var/mail/joe) Feb 28 14:57:45 mouse dovecot: pop3(joe): mbox: root=/home/joe/mail, index=/home/joe/mail, inbox=/var/mail/joe Feb 28 14:57:45 mouse dovecot: pop3-login: Login: user=<joe>, method=PLAIN, rip=192.168.6.20, lip=192.168.6.2 Feb 28 14:57:45 mouse dovecot: pop3(joe): Logout. top=0/0, retr=0/ del=0/0, size=0 This is almost exactly what we're chasing, except the new Maildir is not going to be created in the user's home dir, it will be in /mail/<first letter of username>/username. All attempts to make this last adjustment have ultimately modified the behaviour of dovecot so that it only checks the one source explicity given, and then simply fails if it does not exist, unlike the unconfigured behaviour illustrated above where it is able to fallback to a secondary source. A '2nd_default_mail_env' is the type of variable I'm looking to define, if that makes it any clearer. Any advice much appreciated, I've already searched most of the archives for this list without finding anything similar.

[Dovecot] Impact of log files on performance
by vmstech 27 Feb '06

27 Feb '06

Hi - im trawling through my config trying to reduce chances of timeouts etc - I use postgres for all the dovecot and exim4 authentication and location of mail directories etc - and found that by eliminating logging (or reducing to almost none) the queries invovled have gone from >500ms to <3ms - Just wondering if I'll get similar performance gains with dovecot (which is set to be verbose as I could) - esp during connection thx Glenn

Hi All I intermittently get these kind of errors when connecting to my beta2 imap dovecot: reported error 0x8004df0b:'Outlook is unable to download folder (null) from the imap email server for account mymailhost.com'. Error the server is unavailable. Receiveing Reported error (0x800CC0F):'The connection to the server was interrupted' While these are from outlook - I often get one simiar to the first one in my evolution clients. Are these things that can be best managed with some sort of configuration change? What might be other possible causes of these (apart from a power cut to the server? thx Glenn

[Dovecot] RHEL4 configuration
by f00bar 26 Feb '06

26 Feb '06

I just installed a new email server using RHEL4. I only want pop3d services, no imap is desired so I modified the dovecot.conf file by changing to "protocols = pop3". All is working fine. However, dovecot requires access to /home/user/mail or the Thunderbird client hangs when attempting to download email. We have a single /home that is mounted by all servers for all users. We do not want the mail server to mount this /home. So I created directories with the usernames in the mail server's /home. This is not desired from a system management perspective. The files dovecot creates in the /home/user/mail directory appear to be for the use of IMAP which we do not use. How do I configure dovecot to not access /home and to not create any IMAP files? Thank you
