When is a new mail not unseen?
by Philip Colmer 24 Dec '19

24 Dec '19

I'm trying to diagnose a really strange situation where certain emails, when submitted to the mailbox by Postfix, are not considered to be unseen by Dovecot. During testing, I've shut down anything else on the server that might want to access the mailbox. I submit the email to the local postfix instance which then says it has delivered it to the mailbox: Dec 23 09:51:35 ip-10-35-194-108 postfix/smtpd[3283]: connect from localhost[127.0.0.1] Dec 23 09:51:35 ip-10-35-194-108 postfix/smtpd[3283]: 5A0BF40261: client=localhost[127.0.0.1] Dec 23 09:51:35 ip-10-35-194-108 postfix/cleanup[3286]: 5A0BF40261: message-id=<20191223095135.5A0BF40261(a)servicedesk.linaro.org> Dec 23 09:51:35 ip-10-35-194-108 postfix/smtpd[3283]: disconnect from localhost[127.0.0.1] ehlo=1 mail=1 rcpt=1 data=1 quit=1 commands=5 Dec 23 09:51:35 ip-10-35-194-108 postfix/qmgr[1660]: 5A0BF40261: from=< philip.colmer(a)linaro.org>, size=702, nrcpt=1 (queue active) Dec 23 09:51:35 ip-10-35-194-108 postfix/local[3287]: 5A0BF40261: to=<local-it-support@localhost>, relay=local, delay=0.06, delays=0.04/0.02/0/0, dsn=2.0.0, status=sent (delivered to mailbox) Dec 23 09:51:35 ip-10-35-194-108 postfix/qmgr[1660]: 5A0BF40261: removed I then use this command to query the state of the mailbox: sudo doveadm mailbox status -u local-it-support all INBOX and get this response: INBOX messages=142 recent=0 uidnext=5596 uidvalidity=1455577845 unseen=0 highestmodseq=1163 vsize=11315688 guid=2a997739f55ac2560d180000e171d23e firstsaved=1577094051 What can be happening that means that Dovecot doesn't treat a newly delivered message as unseen?

Sieve vacation not getting enough headers "no known (envelope) recipient address found in message headers"
by Marc Roos 24 Dec '19

24 Dec '19

I am getting these errors[1]. With fairly default setup where sendmail is delivering mail via lmtp. Adding these, do not seem to make a difference. Should I add something to the sendmail configuration? sieve_vacation_dont_check_recipient = no sieve_vacation_use_original_recipient = no [1] discarding vacation response for implicitly delivered message; no known (envelope) recipient address found in message headers

Trouble using reverse dsync backup (log in successful but almost nothing happens)

I am migrating an old dovecot 2.2.30 (macOS High SIerra, macO S Server) to a new server with dovecot 2.3.7 (macOS Mojave, macports). To get the data over, I’m trying to do a reverse backup with doveadm between an old and a new mail server, but failing to do so. I’m trying (from the new server, the old server is 192.168.2.67): doveadm -Dv \ -o imapc_host=192.168.2.67 \ -o imapc_user=gerben \ -o imapc_password=’[snip]' \ -o imapc_features='rfc822.size

Is it safe to mix dovecot import/backup/sync between dovecot versions 2.2.30.2 and 2.3.7.1?
by Gerben Wierda 22 Dec '19

22 Dec '19

I am migrating a server. The old one uses dovecot 2.2.30.2 and the new one 2.3.7.1. I don’t want to use any tool that might influence flags on messages. I am using Maildir format on both ends and I have a way to let one server access the data on the other (either using an rsync or a direct access). Could I set up a sync between both to create a smooth migration?

dovecot rejecting connects
by Roy 22 Dec '19

22 Dec '19

I am a newbie to dovecot but not postfix and centos I created a new VM with Centos 8 and installed dovecot and postfix. Postfix is working fine but dovecot rejects connections from anything but the local machine. Locally Trying 10.10.100.157... Connected to 10.10.100.157. Escape character is '^]'. * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE STARTTLS AUTH=PLAIN] Dovecot ready. Machine on same subnet. Windows, Linux, etc. Doesn't seem to matter telnet 10.10.100.157 143 Connecting To 10.10.100.157... Could not open connection to the host, on port 143: Connect failed I made sure the iptables are empty so it doesn't seem to be a firewall issue I put some LOG statements in the iptables and it showed the connect packet arriving and the response packet was ICMP type 3 code 13. Any ideas? Roy

unable to edit wiki 2, here's the edit:
by Steve Newcomb 19 Dec '19

19 Dec '19

In https://wiki.dovecot.org/Migration/Courier , mail_location = maildir:~/Maildir namespace { prefix = INBOX. separator = . inbox = yes } ... is wrong. Apparently it should be ... mail_location = maildir:~/INBOX ...which at least seemed to work, although (by that time?) I wound up re-downloading all mail. Steve Newcomb srn(a)coolheads.com (Unable to edit the wiki page... Mysterious question stood in the way, something like, "How do you prevent spam?" Evidently I don't know the correct answer.

slow logins over login_trusted_network
by Wojciech Puchar 18 Dec '19

18 Dec '19

i've upgraded dovecot on my server to 2.3.9 works properly but saslauthd that uses it for rimap authentication over 127.0.0.1 works SLOW. You need to wait 15-20 seconds before authentication. only imap login over 127.0.0.1 is slowed down, while over any other IP is quick. i had this problem with older version of dovecot but it was about adding login_trusted_networks = 127.0.0.1 but i already have this and logins is slow. how to disable throttling (or better - put other limits) for 127.0.0.1?

Local lmtp proxy on backend server
by Marc Roos 17 Dec '19

17 Dec '19

I receive a local mail when I do a 'mail test' on a backend svr1 with this[0] configuration. However when I just add only one configuration change 'lmtp_proxy = yes' I am getting these errors[1]. I would expect this email to still be delivered locally, should this be working or do I misunderstand the lmtp proxy functionality?

Yields this, which is the same I got when trying to debug using doveadm acl, it seems like the shared mailboxes aren't placed in the shared namespace at all. A1 SELECT Shared/user(a)sharer.dk A1 NO Mailbox doesn't exist: Shared/user(a)sharer.dk (0.006 + 0.000 + 0.005 secs). -- Peter Reinhold
