Further to another post where an IP on one of my servers has been blacklisted (cause has been resolved).
Just to recap. One of my client’s local exchange server got compromised. Leads of spam was sent via their server through my server.
My server has just one IP number allocated to it at the moment. If I get another IP allocated, can I easily change the IP number that email is sent from or is there another, better way ?
I figure that another IP number would resolve the blacklisting problem while I get the original IP number unlisted.
I believe you’ll be able to use the smtp_bind_address as a parameter in your master.cf file in order to specify which IP address should be used to send outgoing emails.
