You certainly can do this. You need to make sure your ISDN line has a
static IP address. IF it does, then add a second MX record pointing to the
IDSN connection. All MX records have a field called "Priority". The higher
the #, the higher the priority.
In your cases, use two MX records like this:
yourdomain.com 20 MailServer ---This is for the DSL
connection....higher priority number (20)
yourdomain.com 10 MailServer2 --- This is for the ISDN
connection.....lower proiority number (10)
Then have two "A" records....
MailServer pointing to IP address of DSL connection
MailServer2 pointing to the IP address of the ISDN connection..
That should do it.
Hope that helps
