[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? [BTW: Is there a searchable mail archive of the Dovecot list?] Bye, -- Steffen Kaiser

[Dovecot] SquirrelMail IMAP protocol errors?
by Schettino, John Charles 08 May '05

08 May '05

I use Squirrelmail to filter messages, and it's doing this: raw log in: A009 UID SEARCH CHARSET ISO-8859-1 ALL Header X-Spam-Level {4} **** A010 LIST "" "spam" raw log out: * SEARCH A009 OK Search completed. * BAD Error in IMAP command : Unknown command. * LIST (\NoInferiors \Marked) "/" "spam" A010 OK List completed. it goes on like that in the log for every filter. What exactly is the BAD Error there, and is it something I can fix?

[Dovecot] Setting location for indexes
by dovecot.7.signal11＠spamgourmet.com 08 May '05

08 May '05

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 ? (b) is there a way to specify with the 'default_mail_env' (or in some other way) the location of **only** the indexes (and let dovecot autodetect all else?). 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?

[Dovecot] Help configuring dovecot for SSL
by Knute Johnson 04 May '05

04 May '05

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
by James Berry 03 May '05

03 May '05

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? I'm managed to throw out the uidlist, but that means they get a whole dump of new mail. -jdb
