[TriLUG] Re: Need a Stupid Sendmail trick

[Lance A. Brown]

If you are using a recent version of sendmail, this should be easy. 
Port 587 is designated as a submission port for email clients unable 
to access port 25 for whatever reason.  On recent Red Hat systems you 
just need to uncomment the correct line in /etc/mail/sendmail.mc and 
remake the sendmail.cf file.  I've been using this feature to support 
email submission using STARTTLS on my server at home for quite a while.

Lemme know if you need more pointers/assistance.
