Back-up mail protocol/port?

Dear ZoneEdit support,

I am using Back-up mail service for a couple of years now.
Unfortunately my new ISP decided to block the incoming port number 25 on their firewall, so my server is unreachable through them.
I could still use ZoneEdit's backup mail as my primary MX handler, but would that be able to contact my server on the other possible standard ports (like 587 SUBMISSION or 465 SMTP/S) which are not blocked and still standard for mail servers?

Regards
Robert
