However, whilst it might be possible to enter any From: address in mail sent from MTAs that I install and maintain, it isn't possible at all to send any mail without authenticating with a user name and a password. This user name is then used in the envelope sender dialog with the MTA (EHLO/MAIL FROM:/RCPT TO:/DATA). If the authenticated user then tries to use any other MAIL FROM:, the server won't let him. I'll always know which of my users sent which mail to whom from my servers - this is a recent Postfix smtp AUTH jail. Simply because I won't tolerate forgers or spammers on my patches.
Firstly, I'm not talking about MTA issues, I'm simply talking about making it *easier* for users of Evolution as a mail client to be able to implement such an anti-spam technique. It's a matter of making it easier, it is *not* a new phenomenon, nor is it a very complicated request. Sure, I wish this kind of thing wasn't needed, just as I wish the sun would come out everyday (alas, I live in England...) - but we live in a world full of spam. I'm talking about + extensions, which shouldn't be blocked by your system, they're simply an extension of a normal email address, which most MTA's can deal with. It's not as though we're inserting useless email addresses here there and everywhere. Yes, it can be abused, yes people can put whatever they want, but they can do that anyway, and how many spammers are going to take the trouble of using MUA's such as Evolution to fling their spam around the world at unsuspecting innocents? Answer: not many. They'd much rather use malware and zombies to propagate their filth. Oh dear, I rambled again.
