Has anyone considered implementing C/R at the SMTP level?
Yes. Did you search the list archives?
I found one reference here... http://www.mail-archive.com/[EMAIL PROTECTED]/msg05755.html ...
"3) is it possible to block the message at SMTP level, just before DATA, by issuing temporary error code until the message is accepted?
No. TMDA's data is user-specific, which means the MTA has to determine the user to whom the mail is directed before TMDA can do anything. Given that this varies by MTA and is sometimes not done by the SMTP server at all (later processes determine this), TMDA has no effective, general way to get involved."
Actually, it is possible. With qmail and sa-analyze, you can run any program and process the message however you want before it is queued for delivery. Why couldn't you determine the recipient and check the user's whitelist/blacklist?
What other references to this do you know of on in the archive? What has been the general consensus on the idea?
