[afrinic-anti-spam-discuss] Mail Server Blocking IP Address

[Adeosun Tosin]

Dear All,

 

 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.

 

 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.

 

Kindly advice.

 

Regards

 

Tosin Adeosun
