[NTLUG:Discuss] Email Setup Help!?

[David Simmons]

guys - have recently setup and moved my email server to the Qmail Toaster
system (http://qmailtoaster.com) (on CentOS 4) and it's been working
GREAT! for the most part.

Some messages are not getting through (while most are)...and I'm sure it's
one of my configuration files (and not supplying the right info to
their's) - here's a few of the error messages I've received:

Connected to 192.104.67.6 but my name was rejected.
Remote host said: 501 5.0.0 HELO requires domain address

Connected to 204.127.202.26 but my name was rejected.
Remote host said: 501 missing fully qualified domain name

Connected to 205.188.156.185 but my name was rejected.
Remote host said: 501 SYNTAX ERROR IN PARAMETERS OR ARGUMENTS

Connected to 67.155.11.190 but my name was rejected.
Remote host said: 501 Syntax: HELO hostname

so I obviously need to change my name...but which config file do I start
with??

Thanks - dave
