Temporary Lookup Failure

[Brad]

Hi Christian, Noel and Skeeved,

Found the offending postfix -o virtual map in master.cf and removed it.

Re-tested email and new error but the warning for the virtual is gone:

Sender address rejected not owned by user

NOQUEUE reject RCPT from unknown[10.10.1.102] 553 5.7.1 
<steve at samedomain.com>
sender address rejected: not owned by user steve; 
from=<steve at samedomain.com> to=<steve at samedomain.com>
proto=ESMTP helo=<localhost.localdomain>

Answering the rest inline

Thanks for everyones help,
Brad

Correct from Thunderbird no auth issues or errors.

No I can not send emails to other users I get the same similar error 
that the user "Sender address rejected: not owned by user <user> Please 
check the message recipient and try again."

Not sure if LMTP is used when calling mail command from the local mail 
server but that appears to work only, not from the MUA.

Yes postfix is setup to use sasl auth and TLS. I would like to have all 
of them setup and ready and limit as needed via the firewall.

ended up being a -o rule that slipped by in master.cf

I did go through that process but was still getting at that time the 
Temporary lookup errors. Should I re-create these?

Would you like a postconf -n or all the individual files for postfix and 
dovecot?
