You may want to > investigate these settings in postfix. You're right. How could I forget this? I've been bitten by these silly transport entries too. Putting these in a distribution aiming at solidity like Trustix is a major goof IMHO. They're pointless, mostly undocumented, obviously do not apply to many situations (like when using a relayhost!), they create confusion. I'd create a bug entry if the Trustix Bugzilla weren't as completely unattended for as it seems to be now :-( Greets, _Alain_ _______________________________________________ tsl-discuss mailing list [email protected] http://lists.trustix.org/mailman/listinfo/tsl-discuss
