[Dovecot] dovecot >1.1.3 + antispam plugin issues
by Marcin Rzepecki 16 Dec '08

16 Dec '08

Hello, i have following problems using dovecot-antispam plugin (Dovecot >1.1.3, FreeBSD 8.0-Current, dovecot-antispam 1.0/1.1) dovecot-antispam compiled using dspam-exec/mailtrain, with/wo debugging (i've tried all possibilities) When i try to move message to SPAM folder (using dspam-exec backend) i'm getting IMAP error: antispam signature not found and in dovecot logs: Nov 23 23:44:24 freebsd dovecot: IMAP(mr): Next message unexpectedly lost from 2708619 Using mail backend gives this error too(only IMAP error changes: failed to read mail beggining). Commenting out following code in mbox_read_from_line function (in src/lib-storage/index/mbox/istream-raw-mbox.c) helped and plugin was working correctly, but only with Dovecot <=1.1.3. if (stream->istream.v_offset - rstream->hdr_offset + new_pos > rstream->mail_size) { /* istream_raw_mbox_set_next_offset() used invalid cached next_offset? */ i_error("Next message unexpectedly lost from %"PRIuUOFF_T, rstream->hdr_offset + rstream->mail_size); rstream->eof = TRUE; rstream->corrupted = TRUE; rstream->istream.istream.stream_errno = EINVAL; stream->pos = 0; return -1; } Now, with versions >1.1.3 this won't helps and plugin fails. Anyone knows how to get it working? I would like to upgrade to newest dovecot release Best regards, mr

[Dovecot] Problem with managesieve (and virtual users?)

Hello, I use the debian packages from http://xi.rename-it.nl/debian/ version 1.1.7-0~auto+17 If I put a sieve script into /home/vmail/sieve-scripts/test.de/test.sieve it is used, so cmusieve works.

[Dovecot] Replace Domainname in Mail Location
by Manuel Schmidt 15 Dec '08

15 Dec '08

Hello, I dont fully understand how the domain name replacement in mail_location takes place. If I connect to the server using my username as in the text file i can not access my Maildirs as %d gets not replaced. If i user username(a)domain.com the %d is correctly replaced. But, how would i configure my mail_location, to take the domain part from the server name i connect to? So i could set up my client to connect to mydomain.com and have just my username set as login? I did not find a variable that seems to be more correct than %d. So i guess i have to configure that elsewehre? In userdb? Here is my conf # 1.1.1: /usr/local/etc/dovecot.conf protocols: imap listen: 80.69.46.51:143 disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login login_greeting: Druckbar!

[Dovecot] Horde IMP w/ dovecot folder list
by LÉVAI Dániel 15 Dec '08

15 Dec '08

Hi! I'm using dovecot-1.1.7, Horde-3.3.2 and IMP-4.3.2. The left-side folder list has some folders, whos names contains localized (non-ascii) characters. This is displayed correctly when I select the "English (American)" language entry on the login page from the dropdown menu. But when I choose my locale, which is "Magyar" (Hungarian), the folders won't display the correct characters. It's like this: With "English (American)" locale: Ügyfél With "Magyar" locale: &ANw-gyf&AOk-l The latter is the same displaying as with the folder's name on the filesystem: # ls -1 user/Maildir/ [...] .&ANw-gyf&AOk-l/ [...] I've sent this message to imp@ but, they say it is a problem with my mailserver, which I suspected, because the wrong folder names are exactly the same as the folder names on the filesystem. Is there any way to solve this? Thanks in advance, Daniel -- LEVAI Daniel PGP key ID = 0x4AC0A4B1 Key fingerprint = D037 03B9 C12D D338 4412 2D83 1373 917A 4AC0 A4B1

[Dovecot] 1.1.7: quota problem, unable to delete mails when quota exceeded
by Arkadiusz Miskiewicz 15 Dec '08

15 Dec '08

Hi, When user exceeds it's quota then dovecot can't create it's files and it's showing zero mails :( This also means that user is unable to delete it's own mails. Sounds like kind-of bug, right? Dec 15 08:28:37 mbox1 dovecot: IMAP(xxx): open(/var/mail/xxx/dovecot-uidlist.lock) failed: Disk quota exceeded Dec 15 08:28:37 mbox1 dovecot: IMAP(kdudus): file_dotlock_create(/var/mail/xxx/dovecot-uidlist) failed: Disk quota exceeded This sometimes ends with: Dec 15 08:36:43 mbox1 dovecot: IMAP(xxx): Disconnected: Internal error occurred.

Your argument is bogus - see above... again, a basic, properly configured firewall has negligible impact on pretty much any systems resources, even ancient ones... So, yeah, enabling a firewall on a mail server is essentially free, whether talking impact on system resources, or dollar cost. -- Best regards, Charles

[Dovecot] Performance issue about maildir path.
by Zhang Huangbin 15 Dec '08

15 Dec '08

Hi, all. Normally, i use 'domain.ltd/username/Maildir' as users' maildir path, if i change them to hash style, e.g. 'A0/B0/domain.ltd/C0/D0/username/Maildir', will it speed up the index operation for MDA? If we have 10000 users, which maildir path style will improve performance? Thanks very much. :) -- Best regards.
