I am running Exchange 5.5. Certain mailboxes receive excessive spam e-mails. The mailboxes ironically are alias names (i.e., email@example.com, firstname.lastname@example.org, etc.). If I can't do it through Exchange 5.5 (please let me know if I can!), what software do you recommend to filter or block these kinds of e-mails and other irritating spam?
I think third-party products are going to be the way to go until Exchange 2003 ships with its anti-spam features (and even then you still may want some supplemental third-party software). For now, you have several vendors to choose from:
- GFI MailEssentials for Exchange/SMTP
- Open Relay Filter Enterprise Edition
- Trend eManager for ScanMail
There's also Mime Sweeper, Mail Marshall and others, which you should be able to locate on the Web.
