How can you redirect your smtp traffic to another port than 25? My ISP blocks incoming traffic to port 25.

I've been using ZoneEdit.com for this purpose for years (incoming mail traffic goes to another port and I redirect it via my firewall internally to port 25), but with the new system I cannot do it anymore.

I'm not sure if I can do this by configuring MX and A records in the right way or if I need a SMTP redirecting service (such as rollernet.us)?

I'm not an expert in Zone records but generally I know my way around for website traffic.
