[ale] sendmail -mindspring-ISP ignorance

[Armsby John-G16665]

I now have sendmail working better.  I can send as root to root and that works.  I can send email outside of the mindspring.com domain.  I CAN NOT send email to my mindspring account.  Obviously this relay business and domain name is causing my sendmail to think that the mindspring account is part of the local host.  I guess it is not going to relay anything inside of mindspring.com  I THOUGHT I had removed any reference in my config files to mindspring.com, i.e. hosts file?  Since my Linux box is a DHCP setup, I should have NO DOMAIN listed anywhere?  That way any domain would be relayed to mindspring?

Getting there....... Thanks for your help.

John

Try changing to

DSmail.mindspring.com

Mindspring likes to change its server names and IP addresses when they
upgrade hardware because they're too stupid to have the new system have
the same name and IP address as the old system and simply rename the old
system (now destined for some other service).  They also cannot be
bothered to send email to their customers when this happens.

Note also that there must not be a space in this line.

Further, your sending system address must be that of a real system resolvable
through a DNS server that only sees systems on the Internet.

I deal with the latter by doing "hostname someonereal.com" on my system;
I don't know the proper sendmail.cf or sendmail.mc command to fake this
offhand.
