Re: Syntactically invalid argument(s)

Geffrey,

There is a problem with Microsoft Exchange email servers using the underscore in
their helo and\or DNS names despite the fact that this has been brought to
Microsoft's attention that this is in non-compliance with the RFCs regarding
SMTP helos and DNS.

SOOO....in order to detune your Linux machine to work with all the exchange
servers in the world, you have to put this in your configuration file:

### Accomdates lame-o Microsoft Exchange Servers using underscores
### in their helo

helo_allow_chars = _

This is in my current exim\exiscan configuration file.

G'luck,
