Not to sound "forum cop", but did you try to google "501 Syntactically invalid EHLO argument" and look at some of the answers? There are about 29000 results when I checked. adding exim knocked it down to 24,200.

Hi Larry,

I did Google "501 Syntactically invalid EHLO argument" but I got fed up looking through the 1000th that referred to Mozilla or exim. All I wanted to know if anybody else had had similar problems, or could point me in the right direction.

Regards
Mike

There is a problem with chars used in login name.
Login name is also used in EHLO command.
Allowed are: alpha chars + numeric + hyphen (@ is invalid)


Fix:
replace vstate = newState(2, "EHLO " + C_User + crlf,hsocket).
with
vstate = newState(2, "EHLO " + vLocalHostName + crlf,hsocket).

in smtpmail module

Hi All,

There was a simple answer - our Email hosting supplier had changed the machine which was our SMTP server, and did not tell us. They also changed it so that we needed to have authentication. After lots of frustrating phone calls the system is now working again.

Many thanks
