I did that.
But in case I didn't, for instance, some other user is trying to send mail
via outlook express, my server should reject the e-mail with some sort of
error message "connection failed" or "relaying denied".
That didnt happen.
Current status is:
if somebody outside my network configures outlook express to use my SMTP
server and then tries to send a message to any address that belongs to the
domains I host, the mail is accepted.
If the destination e-mail belongs to other domains (which i do not host),
the mail is rejected.
I think this way somebody might still be able to relay mail through my smtp
server by "masquerading" the identity of the destination.
A couple of months ago I received a message whose target address was in the
form
"[EMAIL PROTECTED]"@mydomain.com
and my mail server accepted the message!
Also, I just noticed a message in my server:
safesasl (/etc/sasldb) failed. no such file...
Im using plain text authentication, so I don't know why sendmail is
expecting to find sasl.
