Re: Problem with sending mail from localhost but not remote host

Hi, I have finally figured out the problem and it was nothing to do with Postfix. The application on the local server had been misconfigured and was supplying an incorrect value (undefined) to the BCC field which had been completely overlooked in the logs. Apologies for taking up your time

Problem with sending mail from localhost but not remote host

Hi, I am relatively new to postfix but have worked with many mail systems over the years and am quite familiar with various flavours of Unix/Linux. My problem is as follows: I have a Centos 6.5 system running Plesk V12 on which I have selected Postfix as the mailing system - let’s call this

Re: Problem with sending mail from localhost but not remote host

There is no undefined in Postfix so you have a bug in your database lookups. Test the queries (as seen in logfile) by hand. When a result does not exist, the database MUST return NOTFOUND The database MUST NOT return an empty result. The database MUST NOT return undefined or other crap.

Quite possibly it is, see: http://www.postfix.org/DATABASE_README.html#safe_db The best solution is to use CDB, rather than Berkeley DB for these, if your Postfix package supports CDB, use it. CDB performs updates atomically and uses less memory, ... If switching to CDB is not
