[Dovecot] Still virtio problems
by Erich N. Pekarek 16 Jun '13

16 Jun '13

Hello! As posted on May 27th this year, dovecot 2.1.7 does not allow for the mailstore to be located in a virtio partition. I still receive fstat()-errors on the lock files in this combination: May 27 12:54:51 host dovecot: imap(test@mydomain): Error: fstat(/var/vmail/mydomain/test/.quotausage.lock) failed: No such file or directory May 27 12:54:51 host dovecot: imap(test@mydomain): Error: file dict commit: file_dotlock_open(/var/vmail/mydomain/test/.quotausage) failed: No such file or directory May 27 12:54:51 host dovecot: imap(test@mydomain): Error: fstat(/var/vmail/mydomain/test/Maildir/dovecot-uidlist.lock) failed: No such file or directory Config includes: mmap_disable=yes dotlock_use_excl=no Any ideas? Thanks Erich

[Dovecot] dovecot creating unknown users
by Yann Shukor 16 Jun '13

16 Jun '13

Hi We recently installed a dovecot postfix roundcube debian wheezy serverIt is now in production and we are feeling our way as we progressivelyadd new users to this local server. I noticed that dovecot is creating user directory structures for unknown users withinour domain in /var/vmail, even though we have setup a static users.conf db file. I tried omiting the "allow_all_users=yes" parameter but that doesn't seem to be linked to this issue Sorry if this has been asked a number of times already Is there an easy way to search the archives of this mailinglist ? Thanks yann # 2.2.2 (45399357008a): /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-4-686-pae i686 Debian 7.0 ext4 auth_debug = yes auth_mechanisms = plain login auth_socket_path = /var/run/dovecot/auth-userdb auth_verbose = yes disable_plaintext_auth = no first_valid_gid = 5000 first_valid_uid = 5000 hostname = holimail.holinice.com last_valid_gid = 5000 last_valid_uid = 5000 listen = * mail_debug = yes mail_gid = vmail mail_location = maildir:/var/vmail/%d/%n/Maildir mail_privileged_group = mail mail_uid = vmail 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 ihave namespace inbox { inbox = yes location = maildir:/var/vmail/%d/%n/Maildir mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = subscriptions = yes } passdb { args = scheme=CRAM-MD5 /etc/dovecot/users.conf driver = passwd-file } passdb { driver = pam } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } postmaster_address = azurtem(a)holinice.com protocols = " imap sieve pop3" service auth-worker { user = $default_internal_user } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } unix_listener auth-userdb { group = vmail mode = 0600 user = vmail } } service imap-login { group = dovecot inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } } service imap { process_limit = 1024 } service pop3-login { inet_listener pop3 { port = 110 } inet_listener pop3s { port = 995 ssl = yes } } service pop3 { process_limit = 1024 } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = uid=5000 gid=5000 home=/var/vmail/%d/%n allow_all_users=yes driver = static } userdb { driver = passwd } protocol lda { mail_plugins = " sieve" }

[Dovecot] Turn off IMAPS?
by Simon B 15 Jun '13

15 Jun '13

Hi I've upgraded to 2.1.7 and finally decided to turn off imaps and pop3s because these days everyone uses tls over 143 anyway. But it's on and I can't figure out why. I only have non-ssl versions specified: protocols = imap pop3 I've stopped and started and the ports are still open and netstat says dovecot is listening on them.. mail:~# netstat -tulnp | grep dove tcp 0 0 0.0.0.0:993 0.0.0.0:* LISTEN 29340/dovecot tcp 0 0 0.0.0.0:995 0.0.0.0:* LISTEN 29340/dovecot tcp 0 0 0.0.0.0:110 0.0.0.0:* LISTEN 29340/dovecot tcp 0 0 0.0.0.0:143 0.0.0.0:* LISTEN 29340/dovecot tcp6 0 0 :::993 :::* LISTEN 29340/dovecot tcp6 0 0 :::995 :::* LISTEN 29340/dovecot tcp6 0 0 :::110 :::* LISTEN 29340/dovecot tcp6 0 0 :::143 :::* LISTEN 29340/dovecot Any ideas?

[Dovecot] Auto-responder to handle unencrypted (and/or unsigned) email messages whose origin is not localhost
by Ben Johnson 15 Jun '13

15 Jun '13

Hi, everyone, I'm surprised how little exists on the Internet regarding this particular subject. Given the recent headlines, that is about to change, I'm sure. I have a need to send an automated response to all senders who attempt to send unencrypted and/or unsigned email to a specific mailbox on my system. (Messages originating from localhost should be exempt.) I would like for the auto-reply to include a customized message with the appropriate public PGP key contained therein. Has anyone accomplished this? If not, some basic theory as to how one might go about achieving this would be greatly appreciated. Perhaps this is a job for Dovecot's "sieve_before" directive. Would this simply be a matter of checking the message body for the expected patterns, e.g., starts with "----- BEGIN PGP MESSAGE -----", etc., etc. and sending an automated reply with the public key if the expected strings are not present? Any additional thoughts would be very helpful! Thank you in advance, -Ben

Ive migrated from a qmail+Courier-IMAP setup to a Postfix+Dovecot setup. I'm using maildirs in both places. Is there a safe/preferred way to bring my old messages over without them being marked as new in Dovecot ? -- Aj.

[Dovecot] Pam authentication failure message but it works
by Wayne Andersen 14 Jun '13

14 Jun '13

I am running Centos 6.4 64bit. Dovecot 2.0.9 I am getting the following messages in /var/log/secure, which looks like the pam authentication is not working but the users are allowed to login and the system works great. I am wondering if pam is actually failing and yet the system is getting the login info from elsewhere, or is this just a nuisance message? /var/log/secure Jun 12 23:11:29 smtp auth: pam_unix(dovecot:auth): authentication failure;

[Dovecot] Autocreation the home folder
by Joan 14 Jun '13

14 Jun '13

Sorry if this has been already asked, but I haven't been able to find a solution, I am trying to migrate a dovecot 1.2 config to 2.1, the 'dovecot -n > dovecot.conf' migrated all the setup without issues, and the mail is working as expected. The only issue I've had is with the change with the mail_location, mail_home, that in the 2.1 versions can't be on the same path. After reading in the wiki the various config options ( http://wiki2.dovecot.org/VirtualUsers/Home) I opted to use the 3rd: Home directory under mail, for example: Maildir: home=/var/vmail/domain/user/home/ mail=/var/vmail/domain/user/ mbox: There's really no good and safe way to do it. So I changed from: mail_location = maildir:/home/vmail/%d/%n mail_home = /var/vmail/%d/%n To: mail_location = maildir:/home/vmail/%d/%n mail_home = /var/vmail/%d/%n/home The problem is that those home directories are not created (the mailboxes already existed) automatically, and I am getting these errors: ========================================================== May 10 17:08:59 server dovecot: lda(username(a)example.com): Debug: Home dir not found: /var/vmail/example.com/username/home May 10 17:08:59 server dovecot: lda(username(a)example.com): Debug: Quota root: name=User quota backend=maildir args= May 10 17:08:59 server dovecot: lda(username(a)example.com): Debug: Quota rule: root=User quota mailbox=* bytes=20480000000 messages=0 May 10 17:08:59 server dovecot: lda(username(a)example.com): Debug: Quota rule: root=User quota mailbox=Trash ignored May 10 17:08:59 server dovecot: lda(username(a)example.com): Debug: Quota warning: bytes=15360000000 (75%) messages=0 reverse=no command=/etc/dovecot/quota-warning.sh 75 May 10 17:08:59 server dovecot: lda(username(a)example.com): Debug: Quota warning: bytes=17408000000 (85%) messages=0 reverse=no command=/etc/dovecot/quota-warning.sh 85 May 10 17:08:59 server dovecot: lda(username(a)example.com): Debug: maildir++: root=/home/vmail/example.com/username, index=, control=, inbox=/home/vmail/example.com/username, alt= May 10 17:08:59 server dovecot: lda(username(a)example.com): Debug: Quota root: name=User quota backend=maildir args= May 10 17:08:59 server dovecot: lda(username(a)example.com): Debug: Quota rule: root=User quota mailbox=* bytes=1073741824 messages=0 May 10 17:08:59 server dovecot: lda(username(a)example.com): Debug: Quota warning: bytes=805306368 (75%) messages=0 reverse=no command=/etc/dovecot/quota-warning.sh 75 ======================================================== Am I supposed to create the folders via an external script? Or is there any option to make this automatic. Regards, Joan
