Hi,
I'm having exactly the same problem. I have an older server mydomain.com and I recently ordered am additional server mydomain.com.br.
My clients in the new machine can't send e-mail from their accounts to accounts in the older server, ex.:
user@userdomain.org.br to
me@mydomain.com
My older server replies:
SMTP error from remote mail server after MAIL FROM:<user@userdomain.org.br> SIZE=1655:
host mydomain.com [xxx.xxx.xxx.xxx]: 550 "REJECTED - Bad HELO - Host impersonating [main.mydomain.com.br]"
Solokron, did you have your problem solved?
Any answers will be highly appreciated.
Cheers,
Ricardo
