[Dovecot] Timeout when receiving messages with attachment
by spart cus 28 Mar '06

28 Mar '06

Hi guys, just recently got a problem with my mail server. My clients are comlaining that whel receiving theyre emails after 7 mails received suddenly the connection has timeout. Another scenario is with attachments. Sending 1MB of attachment is not a problem, but receiving this attachement is. Suddenly it timeout for some while. Anyone has a solution for these ? tnx --------------------------------- Yahoo! Messenger with Voice. PC-to-Phone calls for ridiculously low rates.

We're new to dovecot (and really enjoying its speed and good sense!) We are delivering via exim, not yet using the dovecot-lda, and we are delivering to maildirs, but we don't seem to have any dovecot-uidlist files. What are we missing? Thank you, Marilyn

[Dovecot] dovecot died
by Marten Lehmann 28 Mar '06

28 Mar '06

Hello, today our dovecot imap server died. The following message appeared in the logfile: dovecot: Mar 23 07:00:58 Error: pipe() failed: Too many open files We have one dovecot instance for pop3 and one for imap, so while the pop3-service was still available, the imap-service was not running any more. I've seen a lots of users keeping there imap-connections idle for hours, often more than one per mailbox. How can I limit this? Can I limit the maximum time a connection can be open? Regards Marten

[Dovecot] Re: OS X-centricities? Too many files, temp, indexes, etc...
by Roger Weeks 27 Mar '06

27 Mar '06

We're an ISP with approximately 9000 email customers. Up until early in January our primary mail servers ran on OS X, with exim as the MTA and courier-imap as the pop/imap server. We had continual problems with courier on OS X. The load it generates on the machine is horrible. You'll get absolutely no help from the courier mailing list or developers with OS X issues. When we started evaluating Dovecot, we first attempted it on OS X, however we were unable to get it running in an NFS environement on OS X in any sort of stable manner. I can't recommend highly enough getting off of OS X if you can for mail services. We went to Red Hat machines, and they have been amazingly stable and reliable. I love OS X, and use it for other things, but it makes a bad mail server at least for the volume of mail we process. -- Roger J.

[Dovecot] LDA sieve library
by Luca Corti 27 Mar '06

27 Mar '06

Hello, is the LDA linked against the Cyrus SIEVE library or against the fork at libsieve.sourceforge.net ? It seems Cyrus SIEVE from src/libsieve/README in the lda sources. libsieve seems to be better suited for inclusion in non-cyrus software and should be completely independent from libcyrus. The README for cyrus version of libsieve also states that: "It should compile without libcyrus, but then it does not implement the "address" test." thanks -- Luca Corti PGP Key ID 1F38C091 BOFH excuse of the moment: Interference from the Van Allen Belt.

[Dovecot] FreeBSD 5.4/Dovecot 1.0.b3: lots of error messages
by Martin Jangowski 27 Mar '06

27 Mar '06

Hi! I installed Dovecot from the FreeBSD port. I have about 20 users on this machine and used popper before switching. I get a lot of error messages like: dovecot: Mar 21 10:03:41 Error: pop3(xxx): mbox sync: UID inserted in the middle of mailbox /var/mail/xxx (37326 > 35874, seq=1, idx_msgs=26) dovecot: Mar 21 10:06:17 Error: imap(yyy): mbox sync: UID inserted in the middle of mailbox /var/mail/yyy (37352 > 36945, seq=1, idx_msgs=2) dovecot: Mar 21 10:06:18 Error: imap(yyy): kevent(1) in io_loop_handle_add() failed: Bad file descriptor dovecot: Mar 21 10:06:18 Error: imap(yyy): kevent(1) in io_loop_handle_remove failed: Bad file descriptor dovecot: Mar 21 10:06:22 Error: imap(yyy): mbox sync: UID inserted in the middle of mailbox /var/mail/yyy (37354 > 36945, seq=1, idx_msgs=205) Most of the errors are the mbox sync messages. The users report that they get all mails double, triple and more... I think this is connected to the UID problem. My config file looks like that: protocols = imap imaps pop3 disable_plaintext_auth = no log_path = /var/log/dovecot.err info_log_path = /var/log/dovecot.info log_timestamp = "%b %d %H:%M:%S " login_process_size = 64 verbose_proctitle = yes first_valid_gid = 0 mail_extra_groups = mail default_mail_env = mbox:/var/mail/%u protocol imap { imap_client_workarounds = delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep } protocol pop3 { login_executable = /usr/local/libexec/dovecot/pop3-login mail_executable = /usr/local/libexec/dovecot/pop3 pop3_uidl_format = %08Xu%08Xv pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } auth default { mechanisms = plain passdb pam { } userdb passwd { } user = root } plugin { } Any ideas?
