This is a mail routing issue, and it's best attacked in DNS, no?
I assume this is your AV mail hub, followed by Imail?:
# dig citcomm.com mx
;; ANSWER SECTION:
citcomm.com. 1H IN MX 0 mail2.citcomm.com.
citcomm.com. 1H IN MX 10 mail.citcomm.com.
;; ADDITIONAL SECTION:
mail2.citcomm.com. 1H IN A 208.226.190.21
mail.citcomm.com. 1H IN A 208.226.190.18
And your Imail accounts send their outgoing to mail.citcomm.com ?
Just change the A record for mail.citcomm.com:
mail.citcomm.com. A 208.226.190.21
Now, without your users changing anything, their local mail goes to
the AV hub, gets scanned, and in the local routing table of the AV
machine, have this routing entry:
citcomm.com 208.226.190.18
So the Imail users' outgoing mail to other local Imail accounts gets
routed through the AV hub and then to Imail.
