[ale] [OT] Sendmail (?) woes

[Mike Millson]

I added the following at the end of my sendmail config file, based on a tip
I saw from James Kinney:

# Smart host
DSmail.atl.bellsouth.net
# Use this mailer to reach the Smart host
DNsmtp

It's been working for me.

I believe so, but if I recall it is an easy one to fix. Many  mail
servers will reject mail from an account that does not have a valid
reverse DNS, and this appears to be the case. You need to make sure
sendmail thinks it's sending mail from mydomain.org, as opposed to
servername.mydomain.org.

I believe the line you are looking for is going to be something like
this:

# who I masquerade as (null for no masquerading) (see also $=M)
DMmydomain.org
