It worked fine for me for years - what do you have against it?
Sendmail lacks the configurability of Exim.
Maybe, if you refuse to use the milter interface introduced in 2001. Or the available programs that do the work for you.
I refuse connections when the HELO / EHLO does not resolve to the sender's IP address, for example
Sender's IP : 62.25.80.157 = mail1.bemta105.messagelabs.com Host name : mail1.bemta105.messagelabs.com = 62.25.80.157 HELO name : server-12.bemta-105.messagelabs.com = no IP address Date : Tuesday, 11:04, 12 August 2014, (+01:00)
There's not really a requirement for that. And a multi-homed host or one behind nat may not know what IP you think it has.
Sender's IP : 202.94.83.220 = 202-94-83-220.infra.usd.ac.id Host name : 202-94-83-220.infra.usd.ac.id = 202.94.83.220 HELO name : ASRI-PC = no IP address Date : Wednesday, 06:16, 13 August 2014, (+01:00)
I can restrict sending to some email addresses to white-listed senders.
I can get rid of pests by rejecting with a bounce message 'the recipient's mail box is full'.
I think sendmail can do those natively - or more easily with milters.
I can run a basic mailing list, within Exim, without having to use Mailman.
But why would you?
