hi,
maybe you already know:
clients on Mac which use Apple Mail as email client… can’t send email if “Require SMTP authentication” on the smtp port is OFF…
but if i enable it my server can’t receive emails from external relays and neither locally…
yes, Sendmail…
if i require smtp authentication i can’t receive emails anymore from anywhere outside…
i need to require smtp auth just when MY USERS NEED TO SEND (so only my users can do login to send)
BUT this HAS NOT TO block receiving emails addressed to my users on port 25…
