I have
two Exchange 5.5 SP3 servers in the same site and are blocked for spamming. I
had DNS server with MX records inhouse and a month
back moved the DNS entries to ISP.
When I
try rcpt to: [EMAIL PROTECTED] used to
give error 550 but now is giving '553 bad command format' I am not sure where is
the problem. Couldnot find much info about err 553. I will appreciate if someone
can help me in this regard.
