Dovecot Quota and subject utf-8
by Danilo G. Baio 18 Jul '18

18 Jul '18

Hi. When a user is over quota and a message is rejected, it sends a message back changing partially the subject (depending on the size). With utf-8 it breaks the information, we noticed this behavior when the subject line uses utf-8 and it is broken in more than one line: Subject: Quêm casé erat vim id, vix ín dicit putânt, minim çónsequuntur ea iús. Agam cetêro tê eôs, ád vim ipsum tantâs expetêndis. Ut prõ vidit diçit iudicabit, cum út çômmódo Subject of a delivered message: Subject: =?UTF-8?Q?Qu=C3=AAm_cas=C3=A9_erat_vim_id=2C_vix_=C3=ADn_dicit_p?= =?UTF-8?Q?ut=C3=A2nt=2C_minim_=C3=A7=C3=B3nsequuntur_ea_i=C3=BAs=2E_Agam_?= =?UTF-8?Q?cet=C3=AAro_t=C3=AA_e=C3=B4s=2C_=C3=A1d_vim_ipsum_tant=C3=A2s_e?= =?UTF-8?Q?xpet=C3=AAndis=2E_Ut_pr=C3=B5_vidit_di=C3=A7it_iudicabit=2C_cum?= =?UTF-8?Q?_=C3=BAt_=C3=A7=C3=B4mm=C3=B3do?= Subject of a message rejected with Dovecot Quota: Subject: Rejected: =?UTF-8?Q?Qu=C3=AAm_cas=C3=A9_erat_vim_id=2C_vix_=C3=ADn_dicit_p?=? =?...

Dovecot and Sieve setup
by Will Merkens 17 Jul '18

17 Jul '18

I thought I had sieve working I could create the rules in TB and it says it's communicating properly and saves the file but the sieve rules do not seem to be working. when I look at /var/spool/maildir/domain/user I see Maildir Maildir =uid=1000 inside Maildir =uid=1000/sieve I see my sieve script I created Test.sieve and a tmp directory Should not this be in the main Maildir/sieve directory. -- William Merkens IT Support Analyst Userful Corporation +1 403.538.7767 ext.289 +1 866.873.0091 Suite 300 736 8th Ave SW Calgary AB T2P 1H4 Canada https://www.userful.com

ssl_dh required, even though DH is disabled.
by Eric Toombs 16 Jul '18

Here's my config: # 2.3.2 (582970113): /etc/dovecot/dovecot.conf # OS: Linux 4.17.5-1-ARCH x86_64 Arch Linux # Hostname: vault passdb { driver = pam } protocols = imap service imap-login { inet_listener imap { port = 0 } } ssl = required ssl_cert = </etc/letsencrypt/live/myhostname.com/fullchain.pem ssl_cipher_list = ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES128-SHA:ECDHE-ECDSA-AES256-SHA:ECDHE-ECDSA-AES128-SHA256:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES128-SHA:ECDHE-RSA-AES256-SHA:ECDHE-RSA-AES128-SHA256:ECDHE-RSA-AES256-SHA384 ssl_key = # hidden, use -P to show it ssl_min_protocol = TLSv1.2 My filesystem is ext4. Even though I use ssl_cipher_list to forbid DH, dovecot still doesn't work unless I provide an ssl_dh, delivering the following error: Jul 14 21:48:08 vault dovecot[8349]: imap-login: Error: Failed to initialize SSL server context: Couldn't parse DH parameters: error:0906D06C:PEM routines:PEM_read_bio:no start line: Expecting: DH PARAMETERS: user=<>, rip=10.0.0.1, lip=10.0.0.2, session=<4sGi5/9w3pwKAAAB> While providing an ssl_dh is only a minor annoyance, it would be nice if I didn't have to.

Hi, Just noticed an Android email client called K9 Mail is producing these entries in a server's dovecot log: Jul 11 21:03:28 mx1 dovecot: imap(me(a)example.org): Connection closed (IDLE running for 0.001 + waiting input for 1728.597 secs, 2 B in + 10+0 B out, state=wait-input) in=353 out=2154 Jul 11 21:03:31 mx1 dovecot: imap(me(a)example.org): Connection closed (IDLE running for 0.001 + waiting input for 1731.069 secs, 2 B in + 10+0 B out, state=wait-input) in=389 out=1910 I cannot find out what this means after googling. Any ideas? Best wishes, Sophie

Sendmail Dovecot Trouble
by John Rowan 14 Jul '18

14 Jul '18

I've been struggling trying to get Thunderbird to read e-mail off a CentOS 7 server. Sendmail writes mail in /var/spool/mail I've configured dovecot to try to read from there using Thunderbird (POP3/SMTP). The firewall allows ports 25/110. I verified I have mail in /var/spool/mail but Thunderbird is unable to retrieve that mail. I've googled sendmail / dovecot config, I've looked a the wiki but I just can't figure this out. Please don't suggest using postfix, I just want to get sendmail / dovecot working. [@mail conf.d]# dovecot --version 2.2.10 [root@mail conf.d]# dovecot -n # 2.2.10: /etc/dovecot/dovecot.conf # OS: Linux 3.10.0-327.36.3.el7.i686 i686 CentOS Linux release 7.2.1511 (AltArch) auth_mechanisms = plain login disable_plaintext_auth = no mail_location = mbox:~/mail:INBOX=/var/mail/%u mbox_write_locks = fcntl namespace inbox { inbox = yes location = 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 = } passdb { driver = pam } protocols = ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = passwd } --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus

mdbox + alt storage + purge = wtf ...
by Matt Bryant 14 Jul '18

14 Jul '18

All, Is there a bug in doveadm purge ? Configured alt storage and move messages in inbox to the alternate path all well and good. However, after deleting some messages and running a purge on the mailbox found that all messages got recopied over to primary location. I guess this maybe because its re-writing the file and ditching the purged mail .. but shouldnt it keep a track that they were located on alt storage path ?? rgds Matt
