I have checked in almost every error I had that the error is produced whenever happens a timeout of 30 seconds between opening the connection between the director and backend server and the final delivery of the message in the user's mailbox.
When I have mails with just a few of recipients, I have no problem because this 30 seconds timeout is never reached. But when I have mails with more recipients and my storage has workload it is sometimes reached.
Ah, so it's not really a bug. I thought it might be because there had been such problems before.
But I haven't found any configuration for this 30 seconds timeout. What could it be this option? Because I have configured proxy_timeout=120 in proxy configuration:
pass_attrs = irisMailbox=userdb_mail,homeDirectory=userdb_home,uidNumber=userdb_uid,gidNumber=userdb_gid,=proxy=y,=proxy_timeout=120,irisMailHost=host
This should work..
lmtp/commands.c:#define LMTP_PROXY_DEFAULT_TIMEOUT_MSECS (1000*30)
This is the default, but proxy_timeout should override it.
But then, why timeout is reached after only 30 seconds? Could it be other define timeout like DIRECTOR_CONNECTION_DONE_TIMEOUT_MSECS?
What do you get in logs with auth_debug=yes?
I've got always auth_debug=yes. In the director server, logs are:Jun 12 11:40:39 myotis41 dovecot: lmtp(6595): Connect from 155.54.212.167 Jun 12 11:40:39 myotis41 dovecot: lmtp(6595): Debug: auth input: user=user1 proxy host=155.54.211.163 proxy_refresh=450 Jun 12 11:40:39 myotis41 dovecot: lmtp(6595): Debug: auth input: user=user2 proxy host=155.54.211.163 proxy_refresh=450 .... (more users, a total of 34 recipients) Jun 12 11:40:39 myotis41 dovecot: lmtp(6595): Debug: auth input: user=myuser proxy host=155.54.211.164 proxy_refresh=450 ... Jun 12 11:41:09 myotis41 dovecot: lmtp(6595): Disconnect from 155.54.212.167: Client quit (in reset)
but I have checked with newer errors, all I see in logs are "Connect from" and "Disconnect from" messages. The logs "lmtp...Debug:" are not produced any more (maybe because director has this information yet?)
At backend servers are:Jun 12 11:40:38 myotis34 dovecot: lmtp(16824): Connect from 155.54.211.186 Jun 12 11:40:38 myotis34 dovecot: lmtp(16824, <user1>): wJ9BD7YM10 +4QQAAG5O5Qg: sieve: msgid=182283367.48.1339494011054.JavaMail.tomcat@sakai-prod4: stored mail into mailbox 'INBOX' ...
