by Frank Bonnet 04 Apr '11

04 Apr '11

Hello Switching for Dovecot 1 to 2, I noticed the machine respond slower to users requests , of course it works but response times are a bit longer. Does Dovecot 2 need more system ressources ? ( the machine is the same ) Thanks

[Dovecot] Segmentation fault with vpopmail auth
by Samuel Montosa 04 Apr '11

04 Apr '11

Hi. I am new in the list. First, excuse my english. I am not native speaker. A few hours ago I had a problem with process dovecot-auth and vpopmail. Versions I had using, working, were: vpopmail 5.4.28 dovecot-1.1.12 I tried to compile dovecot-1.2.16. Compilation was well but in execution system said: kernel: dovecot-auth[2842]: segfault at 645f20 ip 0000000000645f20 sp 00007fff69bd3708 error 15 in dovecot-auth[645000+1000] and so. Then, I tried to recompile dovecot-1.1.12 (original version I had working) but system said the same. After investigation, I saw I had mixed of vpopmail versions. Problem was I had /home/vpopmail/lib/libvpopmail.so in my system. When this file is present, compilation of dovecot link dovocot-auth to dynamic library libvpopmail.so, but it is not necessary since I had my system working using vpopmail without this .so. What I recommend is to compile a fresh vpopmail. Now I am using vpopmail-5.4.32 (at now, stable version) and dovecot-1.2.16. First, compile vpopmail and make sure you purge /home/vpopmail/lib/ of libvpopmail.so. Fresh installations of vpopmail, from tar.gz (not from SVN) _doesn't_ build libvpopmail.so, so make sure this file doesn't exist before you compile dovecot. For me, library dependencies are: mymachine:/usr/local/src/dovecot-1.2.16# ldd src/auth/dovecot-auth linux-vdso.so.1 => (0x00007fff63df5000) libpam.so.0 => /lib/libpam.so.0 (0x00007f9f925e1000) libcrypt.so.1 => /lib/libcrypt.so.1 (0x00007f9f923aa000) libdl.so.2 => /lib/libdl.so.2 (0x00007f9f921a5000) librt.so.1 => /lib/librt.so.1 (0x00007f9f91f9d000) libc.so.6 => /lib/libc.so.6 (0x00007f9f91c3c000) /lib64/ld-linux-x86-64.so.2 (0x00007f9f927f7000) libpthread.so.0 => /lib/libpthread.so.0 (0x00007f9f91a1f000) I hope this helps. It was a strange "bug". Regards. -- Samuel Montosa

[Dovecot] Maildir
by Walt Shekrota 01 Apr '11

01 Apr '11

I noticed in Cyrus they seem to address maildir++ recognised by IMAP. I need to know does Dovecot recognise this format? Procmail has an ability to deliver mails to different folders which if unrecognised renders the whole process useless. Does Dovecot have a similar deliver method? Thanks. -Walt

[Dovecot] inotify and network/cluster filesystems
by Jan-Frode Myklebust 01 Apr '11

01 Apr '11

(dovecot v1.2.16) I've notice the log notices about increasing /proc/sys/fs/inotify/max_user_instances on my servers, and started wondering if inotify works for network/cluster filesystems.. I found this: http://www.ibm.com/developerworks/forums/thread.jspa?threadID=311194 which says that there's no mechanism for one node to tell another node that a directory changed for GPFS.. And I would assume the same applies for NFS and other network filesystems. (Yes I know, we should use director to make users sticky to one host -- but we're not yet ready for that for lmtp). So, are there any recommendations for what settings one should use for for filesystems where inotify woun't work ? Are there settings for disabling it (without recompiling)? And does mailbox_idle_check_interval happen in addition to inotify, so that clients will be notified even with a broken inotify ? -jf

[Dovecot] Sieve: unknown tagged argument ':create' for the fileinto command
by mailing＠securitylabs.it 01 Apr '11

Hello, I've upgraded from dovecot 1.2.x with sieve to dovecot 2.0.11 with sieve. I've noticed that folders are no more created at delivery time now. I've read that I have to do two things: lda_mailbox_autocreate = yes in dovecot.conf and fileinto :create in the sieve script. Now the error message I receive is: error: unknown tagged argument ':create' for the fileinto command (reported only once at first occurence). My sieve script: require ["date", "variables", "fileinto"]; if header :contains "subject" "Bacula:" { if currentdate :matches "month" "*" { set "month" "${1}"; } if currentdate :matches "year" "*" { set "year" "${1}"; } fileinto :create "INBOX.Bacula.${month}-${year}"; } else { # The rest goes into INBOX # default is "implicit keep", we do it explicitly here keep; } My dovecot conf: papua:/usr/local/bin# dovecot -n # 2.0.11: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.1 auth_cache_negative_ttl = 2 mins auth_cache_size = 1000 M auth_cache_ttl = 2 mins auth_mechanisms = plain cram-md5 apop auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@& disable_plaintext_auth = no first_valid_uid = 100 last_valid_uid = 105 lda_mailbox_autocreate = yes lock_method = dotlock log_timestamp = "%Y-%m-%d %H:%M:%S " login_greeting = Server ready. mail_fsync = never mail_gid = Debian-exim mail_location = maildir:~/Maildir mail_privileged_group = Debian-exim mail_uid = Debian-exim managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date namespace { inbox = yes location = prefix = INBOX. separator = . type = private } passdb { args = /usr/local/etc/dovecot-sql.conf driver = sql } plugin/mail_log_events = delete expunge plugin/mail_log_group_events = plugin/quota = maildir plugin/quota_warning = storage=80%% /usr/local/bin/dovecot-quota-warning.sh 80 plugin/quota_warning2 = storage=90%% /usr/local/bin/dovecot-quota-warning.sh 90 plugin/sieve = ~/.dovecot.sieve protocols = imap service auth { unix_listener auth-userdb { group = Debian-exim mode = 0600 user = Debian-exim } } service imap-login { client_limit = 256 process_limit = 128 process_min_avail = 3 service_count = 1 } service imap { drop_priv_before_exec = yes process_limit = 256 vsz_limit = 256 M } service pop3-login { client_limit = 256 process_limit = 128 process_min_avail = 3 service_count = 1 } service pop3 { drop_priv_before_exec = yes process_limit = 256 vsz_limit = 256 M } ssl_cert =</usr/local/etc/dovecot.crt ssl_key =</usr/local/etc/dovecot.key userdb { args = /usr/local/etc/dovecot-sql.conf driver = sql } protocol imap { mail_max_userip_connections = 10 mail_plugins = " notify quota imap_quota mail_log" } protocol lda { mail_plugins = quota sieve postmaster_address = postmaster(a)me.com }

[Dovecot] Mail_location and formats
by Walt Shekrota 31 Mar '11

31 Mar '11

Hi, Ok I know that the Maildir hierarchical structure works because I saw it intermittantly in my setup. At times I could look at ALL folders in my client. mail_location = maildir:~/Maildir:LAYOUT=fs http://wiki1.dovecot.org/MailLocation/Maildir this says 1.1 only? My maildir folder has a collection of maildir folders ie each has cur new tmp folders. As an experiment I took the cur new tmp out of my INBOX folder and put it in the root of Maildir. This worked with dovecot using the inbox only or the standard maildir++ format. Although it would not see the old mail in the folder not sure why. mail_location = maildir:~/Maildir This setup also ignores the remainder of folders. I know the dovecot support of maildir is shakey due to standards compliance but this is crazy ... and unusable. Does ANYONE have a working maildir setup in the hierarchical layout? Maildir/ inbox mail-sent outbox otherfolder Fred Sue Thanks. -Walt

[Dovecot] POP3 connection issue & SASL not compiled in
by sunhux G 31 Mar '11

31 Mar '11

After I've configured dovecot for SSL according to the info given in the link below: https://access.redhat.com/kb/docs/DOC-6671 (tried both POP3 & secure POP3 & got the same result) I tested POP3 access from my unblocked (no firewall rule for outgoing) broadband PC's Outlook to connect to the postfix/dovecot server & got the following : Tasks Status ===================== ======== Establish network connection Completed Find outgoing mail server (SMTP) Completed Find incoming mail server (POP3) Completed Log onto incoming mail server (PO... Send test e-mail message Completed (yep, this email was received in postfix mailbox) & seconds later, the following messages returned: Log onto incoming mail server (POP3): The specified server was found, but there was no response from the server. Please verify that the port and SSL information is correct. To access these settings close this dialog, then click More Settings and click on the Advanced tab. Find incoming mail server (POP3): Outlook could not connect to the incoming mail server (POP3). The problem could be the server name or port, or your server may not support SSL. Verify your port and SSL settings in More Settings under the Advanced tab. Q1: What do I need to provide to this list for further troubleshooting? Q2: I have the following log entry in /var/log/mailog : Mar 31 10:48:36 hostname postfix/smtpd[22258]: warning: smtpd_sasl_auth_enable is true, but SASL support is not compiled in Is this related to my POP3 connection issue? Q3: Is the following related to the sasl issue in Q2 & the POP3 connection issue ? [root@host /etc/sysconfig]# saslauthd -v <== expectg postfix to be listed below saslauthd 2.1.19 authentication mechanisms: getpwent kerberos5 pam rimap shadow ldap [root@host /etc/sysconfig]# rpm -qa | grep -i sasl cyrus-sasl-md5-2.1.19-5.EL4 cyrus-sasl-devel-2.1.19-5.EL4 cyrus-sasl-ntlm-2.1.19-5.EL4 cyrus-sasl-2.1.19-5.EL4 cyrus-sasl-plain-2.1.19-5.EL4 cyrus-sasl-gssapi-2.1.19-5.EL4 warning: only V3 signatures can be verified, skipping V4 signature cyrus-sasl-sql-2.1.19-5.EL4 The above cyrus/sasl rpms are old existing packages that were already there in the server a couple of years ago & well before I installed postfix & dovecot in this server. Wondering if they interfere with postfix sasl authentication. There's no issue with this postfix+dovecot box sending & receiving emails.
