I have two MX's, my IMGate and IMail. The IMGate is 10 and the IMail is 20

mistake. with a front-end MX, remove the mailbox server from MX records. This is my standard advice for all IMGate users. and if possible, block access from internet to Imail port 25.


I see that I have a lot of spam go directly to the secondary MX

All MX records get hit by abuse. Imail removed from MX records will still get spam, but much less.


.  Does
anyone see an issue if I add another MX record for IMGate as 30?

useless and counter-productive. Spammers will hit all 3 MXs, wasting more of your bandwidth, with no advantage to you.


To me the
current batch of spam is looking at the last MX server to send too.

probably not, but some spammers may have realized that secondary MXs have the dumb mistake of having less restrictive/no policies than the primary MX, so the backup MX is a "trusted" open door.


I need a backup MX

Probably not. backup MXs are highly over-rated. IMGate is more robust and simpler than IMail.
