What newsletters do that? I never, ever send a newsletter from a nonexistent bounce (envelope sender) address. Quite the opposite. How do you clean your lists if you don't have a drop box to scan? Even if you don't bother cleaning, is there some reason to not at least *devnull* bounces, not reject them? > It seems that this would require the newsletter sender to make sure > the bounce address exists Why shouldn't it? VERP, for example, exists to make list bounce addresses more useful, _not_ to eliminate them. As another benefit, VERP also allows for end-user-created addresses (as in IMail, where -- provided mailbox subaddressing is honored at the MX -- [EMAIL PROTECTED] can send from [EMAIL PROTECTED]). > even if it does nothing but toss any email sent to it. i.e., even if it just stops double-bounces. > It seems a bit silly to create an address that does so, and have to > receive the email that it is just going to trash.

I really don't agree with your premise here at all. I don't know what circumstances would have led you to routinely send mail blasts with nonexistent senders. --Sandy ------------------------------------ Sanford Whiteman, Chief Technologist Broadleaf Systems, a division of Cypress Integrated Systems, Inc. e-mail: [EMAIL PROTECTED] SpamAssassin plugs into Declude! http://www.imprimia.com/products/software/freeutils/SPAMC32/download/release/ Defuse Dictionary Attacks: Turn Exchange or IMail mailboxes into IMail Aliases! http://www.imprimia.com/products/software/freeutils/exchange2aliases/download/release/ http://www.imprimia.com/products/software/freeutils/ldap2aliases/download/release/ To Unsubscribe: http://www.ipswitch.com/support/mailing-lists.html List Archive: http://www.mail-archive.com/imail_forum%40list.ipswitch.com/ Knowledge Base/FAQ: http://www.ipswitch.com/support/IMail/
