<p class=MsoNormal>Dear All,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal> I discover of late that when the IP address assigned to our
clients is not blacklisted and the clients mail server IP is not Blacklisted as-well.
The client is not able to send mail, more so, we only allow our clients to send
mails on port 25 and 587.<o:p></o:p></p>
<p class=MsoNormal> <o:p></o:p></p>
<p class=MsoNormal> It’s like the mail server is seeing spamm coming
from our IP and blocks our IP address and the client will only be able to send
mail after changing their IP. This is not just a client but about 5 clients
that have experienced on their mail servers.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Kindly advice.<o:p></o:p></p>
