</div>Is this your *outgoing* mail host? <a href="http://mail.navigationbd.com" target="_blank">mail.navigationbd.com</a> with IP address of<br>
202.53.168.75?<br>
<br>
If so, it seems your server is being blocked from sending "spam".<br>
<br>
The IP address of 202.53.168.75 blocked from sending to RoadRunner servers. See<br>
<a href="http://postmaster.rr.com/mail_blocks#directspam" target="_blank">http://postmaster.rr.com/mail_blocks#directspam</a><br>
<br>
hotmail is also rejecting mails from that server since it has too many addresses in<br>
the RCPT commands of the SMTP protocol. This is another indication of your system<br>
sending out SPAM.<br>
<br>
So, is your question.... What can I do to make my system send out SPAM in a better way?<br>
<br>
Or, am I misreading what you think you are asking?<br>
