Everything works fine on the old SUN's, but the ones running SUN OS 4.? trash things, yep 'cos of ownership. I attribute the problem to the SUN side of things (because the older OS's work) and I have no intention of fixing it, people here don't bother using the SUN's for mail anyway, we're just running the SUN's 'till they die. Anyway, all mail get's routed through our main mailer one way or another, the mail-host (an IRIS) has "mailhost" as one of it's aliases in the hosts database on the ypmaster (an IRIS). All users have an alias in the ypmaster's /usr/lib/aliases to user@mailhost. This way we can switch the mail-host quickly if we need to. The real problem with the SUN's running 4.? occurs when you delete from the mailbox. SUN's "Mail" screws-up the permissions. So obviuosly my bias is toward the SGI side of things, I'd say go that route or get SUN to fix their version of Mail.
