Oh lord here we go again... Each and every person has their own reasons for having Nyll senders enabled/disabled. Until you know their circumstance it's not mine or anyone else's place to tell then what they should and should not do. So unless you know absolutely everything about someone's environment and their motivation behind a configuration just keep that kind of stuff to yourself unless asked. In this case he wasn't asking rather or not he should have Null Senders enabled or not.

Search the archives...there are a number of reasons you need to have Null Senders enabled. You can copy them to a review box if you're concerned about spam abuse, or outright delete if that's acceptable to all of your users. Without acceptance and delivery, none of your users are getting legitimate delivery failures, and those could be important. Imagine the user that typos the address of someone in an email containing a million dollar contract bid, never gets the delivery failure notice, and misses out on the opportunity (OK maybe one shouldn't rely on just email for a million-dollar contract, but you get the point). RFC says you MUST accept Null Senders. Many mail systems use Null Sender for address verification callbacks, so any system you're trying to send to that does this and gats a rejection may in turn reject or discard your mail for it. There are 3rd part products that can catch things like multiple recipients from a null sender to curb the abuse. As for read receipts, auto-responders, vacation notices, etc. IMHO these are all evil inventions that do more to advertise email addresses to spammers than provide real value to the real recipients of these things, and often generate more false messages to innocent victims when they get sent out to forged sender addresses in response to spam, making you something of a spammer yourself.

Imail is blocking read replys because the "mail from" is blank (it shows in the log as <>) Does anybody know in outlook where this setting is changed? I hate to open up Imail to null senders, I think that's just looking for trouble.
