I see this problem (SGI IRIX 4.0.4).  We run 5 router processes and only
some of them will bloat.  And it usually takes a couple of days to happen. 
I have taken the same approach to working around it but it IS a problem. 
I too am faced with setting up a huge mail machine and would like to use
ZMAILER but this memory problem has me concerned.

We currently pass about 1000-2000 SMTP, BITNET, UUCP and local messages 
through ZMAILER on one of our general timesharing systems (3000-4000 
accounts).  I'm looking at setting up a system this summer with 
20,000-50,000 accounts and significant mail volume (campus-wide mail system).
