Possible Relay??

Long line breakup 2048 chars
I just noticed that sendmail mangles long lines (greater than 2048 chars). I see where this is happening in the source but I don't understand why the code is even there. RFC 821 says that SMTP lines should be less than 1000 characters but SMTP implementation are encouraged to accept lines of unlimited length.... 23 Dec 2006 22:54

Requiring auth for specific email addresses
I've got SASL2 all setup and working, now I'm wondering if it's possible to require auth only for a specific rcpt address? I can't figure out a way with the access db but it looks like maybe with a customized Local_check_rcpt it would be doable? ... 16 Dec 2006 20:13

Rquiring authentication
How do I tell sendmail to require authentication for relaying? I want to configure it to receive email for my domain for anywhere, but any attempt to relay must require TLS/SSL and authentication. I would guess this is pretty standard these days. Reading the various HOWTOs I've found has given me this: defi... 11 Dec 2006 15:33
