I have just upgraded from storm linux (slink) to debian stable (potato). Most things went shockingly well. There was an occasional oddity. After reading through all error messages, I was able to figure most things out. Kudos to the debian team!
Shortly before upgrading, I put server behind a NAT (like masquerade) sonicwall firewall. Things appeared to work fine. About the time I upgraded to new sendmail, I started getting mail authentication errors from external inbound mail. I then received domain validation errors. The result was a lot of deferred mail. The error reported was the MX record didn't match the private IP of my server. What is the best resolution for this? It would be nice if sendmail could IP masquerade for authentication purposes by responding with the MX record IP. I added my domains to my caching DNS server so the LAN could see the local web sites. I have read the apache.org FAQ and didn't see a handy solution which will resolve authentication problems. My DNS doesn't server my domains externally. How do I fake the authentication? Here is my customizations to the .mc file: FEATURE(nocanonify) dnl FEATURE(accept_unqualified_senders)dnl FEATURE(accept_unresolvable_domains)dnl FEATURE(`access_db', `hash -o /etc/mail/access') dnl Any ideas for changes/additions ? I disabled NAT for the temporary solution but want to reduce the requirements to one static IP. If anyone has any ideas, I would appreciate it.
