Hello,
is possible to use the HA feature also for SMTP relay?. Now i have my devices and others that point to mysmtp.domain.com, is sufficient to add the other node that the system do a balancing?
Thanks
Not sure whether I understand the question completely.
If you want to use more PMG for outbound relaying - just add 2 A/AAAA records for mysmtp.domain.com (if that's what you've configured as smarthost in your servers)
