Replication issues master <-> master nfs backend
by William L. Thomson Jr. 24 Mar '16

24 Mar '16

I keep having some replication issues and not sure what can be done to resolve or correct. It does not seem to happen all the time, though for the last ~30 or so minutes and many messages seems to be happening consistent for me. I have 2 mail servers, basically clones, and thus master master replication. Most of the time things work fine. But many times an email or several will arrive on one, and never replicate to the other. I am not as concerned on the never replicating, as I am that the user never gets notified. Mail arrives on say server 1, users are checking mail on server 2, and they never see the email on server 2. This is not always the case, but its happening enough daily. I then log into one and run sync manually. Which usually syncs the mail on both servers, and then it arrives in the inbox. Here is an example, mail is on mail2, but not mail1. I am checking email on mail1 so I am not seeing the 1 email. Mail1 /home/wlt-ml/.maildir/new: total 0 Mail2 /home/wlt-ml/.maildir/new: total 12 -rw------- 1 wlt-ml site1 8502 Mar 22 14:57 1458673024.7643.mail2 Then I manually log into mail2 and run this command, though usually I can run it from either side, and just change the name to the other server. doveadm sync -u "*" remote:mail1 And then I end up with the missing email on mail1, and it arrives in my email client shortly there after Mail1 /home/wlt-ml/.maildir/new: total 12 -rw------- 1 wlt-ml site1 8502 Mar 22 14:57 1458673051.M838843P26735.mail1,S=8502,W=8678:2,T I have no idea why it does this. It seems to happen when when a full sync has taken place per doveadm replicator status wlt-ml. There does not seem to be any settings to force a full vs fast sync more often. No clue if this is even a full vs fast issue or other. I think it tends to happen more when people stay connected to the imap server. I had a theory that closing the email client and opening it again will get dovecot to sync. I believe this is still the case, but not able to confirm 100%. Also users are reporting closing Thunderbird. I can see them logging out and back in in the logs, but email does not replicate or show till I run doveadm sync manually. Tempted to have cron invoke that on the regular, but seems very hackish and likely will have its own issues doing that. Since its not the right way or how things were designed. Not sure if this is a bug or what. Hopefully miss-configuration on my end. Open to any feedback, advice, etc. I can provide replicator configuration but its pretty straight forward and mostly copy/paste from the replication page. Replication works, just seems it is not triggered to replicate at times or something. dovecot --version 2.2.22 (fe789d2) -- William L.

Allowing for multiple recipient_delimiter characters?
by Aaron Lindsay 23 Mar '16

23 Mar '16

Postfix allows the recipient_delimiter configuration parameter to contain multiple characters, splitting on the first such character it encounters. For example, if using 'recipient_delimiter=+-' both aaron+foo(a)example.com and aaron-bar(a)example.com would be delivered to aaron(a)example.com. Is anyone opposed to changing dovecot's handling of recipient_delimiter so that it's the same as that of postfix? If not, I am willing to rebase/merge/address review comments on Lennart Weller's patch[1] to get this functionality upstream. While I think aligning with postfix' behaviour would be convenient for those of us who run a server using both dovecot and postfix, would this break any other common use cases I'm not aware of? Thanks! -Aaron [1] - http://dovecot.org/pipermail/dovecot/2015-February/099660.html (I've talked with Lennart off-list, and he's OK with me working to get his patch merged, as long as I attribute his work to him, but doesn't have the time to work on it himself right now)

protocols.d/ dir empty?
by Kieran 22 Mar '16

22 Mar '16

(I hope I'm doing this right) Hey there. I have a problem with the dovecot protocols. When I do /telnet 127.0.0.1 143/ it gives me a connection refused error. I looked in the wiki and then after trying /doveconf protocols listen /I realized that I don't have any protocols.//I went in //usr/share/dovecot/protocols.d/ and it's empty. How can I fix that?
