SMTP Error

[shanuvarma]

Hi to anyone who can help me as this is doing my head in.

The easiest way to demonstrate this is if you can do the following:

telnet mail.shanuvarma.com 25
ehlo



then you will see that it returns an error - this i do not know how to fix

Can someone please tell me what to look for, check, change etc?

Try this (ehlo with an argument):

[admin@]$ telnet mail.shanuvarma.com 25

ehlo should always be followed by a valid hostname or domain name with working DNS and working reverse-DNS. Anything else can be spam. The next version of SpamBlocker exim.conf will actually check for proper ehlo by default.
