Hi list,
I set up dovecot as IMAP proxy using a master user to login into the backend and
it works beautifully. ?? Next I set out to do LMTP proxying and I struggled
(initially).
I got the log message:
Mar 17 11:23:44 mail postfix/lmtp[2665]: 99A3F219C8: to=<johnny at
doe.com>, relay=10.15.1.2[10.15.1.2]:24, delay=5.1,
delays=4.9/0.05/0.01/0.07, dsn=5.1.1, status=bounced (host 10.15.1.2[10.15.1.2]
said: 550 5.1.1 <"johnny at doe.com*director"@mail.server.com>
User doesn't exist: "johnny at doe.com*director"@mail.server.com
(in reply to RCPT TO command))
My director's passdb setting looked like this:
passdb {
driver = sql
args = /etc/dovecot/sql/my-passdb.conf
result_success = continue-ok
result_failure = return-fail
result_internalfail = return-fail
}
# Add director master user credentials if above succeeded
passdb {
driver = static
args = proxy=y starttls=any-cert \
destuser=%u*director at example.com \
pass=correcthorsebatterystaple \
nopassword=y
skip = unauthenticated
}
In the end I found that setting the `master` field instead of `destuser` solves
the issue. It looks like LMTP does not know how to handle the master user
separator although set. I this known/wanted behavior? Maybe this is something to
mention on the wiki page, it took a while to figure this out...
Kind regards,
Dirk
