Kolab 3.3 / address extensions / recipient_delimiter / plus addressing

[Cornelius Hald]

Hi guys,

I've changed the recipient_delimiter in postfix main.cf from '+' to '.',
which seems to work fine for the postfix part. Unfortunately the mail is
then rejected because lmtp cannot find a mailbox/user.

Probably I have to change something regarding cyrus or lmtp settings,
but I really cannot find out what.

My test user looks like this:
Primary mail: test at example.com

I'm sending mail to: test.extension at example.com
And get the following error:

Nov 11 11:02:33 mail postfix/lmtp[21936]: 5A6DC1D9:
to=<test.extension at example.com>,
relay=mail.skolar.de[/var/lib/imap/socket/lmtp], delay=0.09,
delays=0.04/0.03/0/0.02, dsn=5.1.1, status=bounced (host
mail.skolar.de[/var/lib/imap/socket/lmtp] said: 550-Mailbox unknown.
Either there is no mailbox associated with this 550-name or you do not
have authorization to see it. 550 5.1.1 User unknown (in reply to RCPT
TO command))

Anyone knows what to change to get that working?

Thanks!
