I know some are going to get upset about what I think ... but IMO delete all mail going to root, postmaster, webmaster, and administrator.
If you have IMGate you can block all but postmaster, I've found some mail servers will not receive email if you don't have an postmaster account. Christopher Checca Packard Transport, Inc.

[The root mailboxes fill up and the mail server then bogs down with "mailbox full" GSE replies to non-existent spam senders.] Should I: - Forward postmaster and root mail for all domains to my "master" postmaster account? [That's gonna be a LOT of junk mail for me to personally wade through. We're talkin' tens of thousands of messages per day.] - Delete the unused root and postmaster accounts? [Afterall, they're all disabled by default. And this would allow our clients to setup their own postmaster forwarder to a working mail address, should they want to receive mail server alerts.] - Rename the root and postmaster accounts? - Other options? Any advice is greatly appreciated. Dave -- David M.
