Hi,
Recently had similar problems, I use ADSL with dynamic IP I cured the
problem by not using SMTP to send mail. I instead configured mail to
forward to my ISP's SMTP server and the problem was solved. I think
that this is caused by a DNS problem, (I do not host my own DNS server).
All my clients that have a fixed IP address have no problem sending mail
by SMTP, the problem seems to rear its ugly head only if you are on a
dynamic IP address.
My problem address was AOL .com I received ok but could not reply or
send directly.
Hope this may help.
Regards,
Rick Parsons

I have a EXCH 2000 SP3 server that is having trouble sending emails to
some domains.
Looking at the SMTP log files, an error occurs when using the BDAT
command. It comes back "502 Command Unimplemented".
The most common domains we cannot send to are: Hotmail.com and MSN.com.
There are other domains that we can send messages to, but that we get
errors in the log file. These errors occur when using the XEXCH50
command.
Ther error say "500 Syntax error, command unrecognized". But, the
message
gets sent anyway.
Does anyone have any suggestions?
Thanks!
Cory
