Can't send mail to ONE domain

[mevans]

Hello all,

I have upgraded Mailenable from Standard to Professional and now, when I send email to a certain domain (itt-s.com) the email goes straight into the "Bad Mail" folder and I get the following in the MTA Log file:

08/23/05 09:03:57	Processing file F9F5F28A9B104DE2838C6C30BCC8F82F.MAI from queue SMTP

If I uncheck the memailfilter.exe in the MTA properties, the mail is passed and received fine.

Any ideas?
