Hi All, I am having dovecot installed on my redhat 7. There was an email came to my "Maildir" directory as per the logs. There is an application reading the emails from the Maildir inbox. I have the log stating the email has been delivered to maildir folder below. But the application team says that they didn't receive the email. The emails is also not there in the Maildir folder. Is there any way/log we can see, from Maildir folder, whether the application picked the email? or where that email went (to any server) from the Maildir folder? any such verification is possible? ============= [root@testserver log]# grep EB6A2206818 temp.log May 5 07:35:20 testserver postfix/smtpd[29839]: EB6A2206818: client=test-server May 5 07:35:20 testserver postfix/cleanup[29842]: EB6A2206818: message-id=<AM0PR01MB42257878E93ED4C6> May 5 07:35:21 testserver postfix/qmgr[29801]: EB6A2206818: from=< tester1(a)testing.com>, size=13614, nrcpt=1 (queue active) May 5 07:35:21 testserver postfix/virtual[29843]: EB6A2206818: to=< selfemail(a)testing2.com>, relay=virtual, delay=0.05, delays=0.05/0/0/0, dsn=2.0.0, status=sent (delivered to maildir) May 5 07:35:21 testserver postfix/qmgr[29801]: EB6A2206818: removed ============== Please help me...

Thank you for the reply. Actually there are 7 emails sent by the user. 2 emails are delivered successfully. 5 are missing. All are having the same log with virtual. At present I might not be able to change those settings.... Is there any way to verify they are delivered to them or not? do we have any logs to verify the same?

Dovecot IMAPS : Thunderbird SSL cert issue / Evolution OK
by hanasaki＠gmail.com 05 May '20

05 May '20

Recently thunderbird and Dovecot IMAPS cannot agree on SSL however Evolution, on the exact same system, is working fine with the same accounts. Tried recreating the Dovecot cert and also the thunderbird accounts from scratch. The OpenSSL raw client works fine as well. Would someone also confirm the openssl commands to create a selfsigned cert for dovecot imaps. They cert created does work with evolution; just not thunderbird. Thoughts?

Greetings, Lately I've been seeing this error pop up when running a nightly cron to a backup share with doveadm: Error: stat(/vmail/domain.tld/user/.dovecot-box-sync.lock/tmp) failed: Not a directory: 1 Time(s) This is the command: doveadm backup -u user(a)domain.tld maildir:backupshare/daily/domain.tld/user Our main vmail directory is on an NFS share and seems to be working fine. This has only occurred recently. Can anyone offer any insights into what this is and fixing it if need be? -- Asai

Problems during replication
by Francis Augusto Medeiros-Logeay 02 May '20

02 May '20

Hi, I migrated my dovecot instance to a new server. I moved the mail directories, databases, etc. Replication is on, and I keep having these errors: May 02 16:19:45 dsync-local(francis(a)francisaugusto.com): Error: Couldn't lock /var/mail/vmail/francisaugusto.com/francis//.dovecot-sync.lock: fcntl(/var/mail/vmail/francisaugusto.com/francis//.dovecot-sync.lock, write-lock, F_SETLKW) locking failed: Timed out after 30 seconds (WRITE lock held by pid 178) May 02 16:19:45 doveadm: Error: Couldn't lock /var/mail/vmail/medeiros.co/inis//.dovecot-sync.lock: fcntl(/var/mail/vmail/medeiros.co/inis//.dovecot-sync.lock, write-lock, F_SETLKW) locking failed: Timed out after 30 seconds (WRITE lock held by pid 185) See the errors are both from dsync-local and doveadm. Any tips on how to fix this? Best, Francis

01 May '20

Hello, I would like to know if dovecot/pigeonhole provide a way to do sieve redirection with sender rewriting scheme (srs)? I apologize in advance if that e-mail address isn't meant for assistance, but I've asked on the official irc channel on freenode and was told to direct my query to dovecot(a)dovecot.org, I hope you won't mind. Thanking you in advance Best Regards Mathieu Gosset

Shared folder replication - query - can it be replicated?
by Daniel Botting 01 May '20

01 May '20

Hi, Further to my earlier posting to the mailing list this morning regarding replicating of public namespaces is it possible that a shared name space can be replicated: https://wiki.dovecot.org/SharedMailboxes/Shared We use LDAP, the thought being that an LDAP service account is created and the corresponding mailbox is shared to other mail users on the server. Kind regards Daniel

Public folder replication ( not replicating) - roadmap query
by Daniel Botting 01 May '20

01 May '20

Hi, We have a server pair running Dovecot 2.3.10 (latest stable) version directly from repo.dovecot.org and have mailbox and sieve replication working as required in production. I have setup a test pair with the exact same configuration and on each server setup public name space for a mailbox address such as jobs@ where multiple users would need to subscribe to this to view recruitment emails. This is not replicating as per the advice on the below url: - https://wiki.dovecot.org/Replication Is there an easily maintainable workaround at this time and is this on the roadmap for the developers, if so what time scale is being envisaged? Kind regards Daniel
