Inbound
Yes. The customer should configure his mail server to receive as shown in the example below:
123.123.123.123:400 for all INBOUND mail where [Customers own IP address:Port of choice]
Outbound
Only ports 25 & 587 can be used for OUTBOUND mail.
Can I use a port other than 25 for inbound and outbound emails?
