From: PostfixUser on
I have recently made some changes to my main.cf file.
Prior to the change I was able to send a mail internally just addressing
to the "short" name of a recipient eg
If I were sending to "kevinw(a)company.com", I would address my mail to
"kevinw" the server would handle the rest and deliver the mail.

all mail is working OK, internally/externally, but I seem to have made
the server specifically ask for a fully qualified address ie
"kevinw(a)company.com" before it will send.

my postconf -n is below, has anyone any ideas please. I would like to
get back to short names without breaking the spam stuff I have added.
