[Mimedefang] RE: Mimedefang] Sendmail issue (not sure if MD related or, not)

[Doug Hubbard]

To answer Josephs question about localhost, I was connecting to the 
machine from my laptop and the reverse DNS is where sendmail was getting 
the name (not telneting from the server itself).
I have resolved the issue (one of the two changes I made has fixed it, 
but I haven't isolated which yet and want to let the flames subside 
before I change one back and possibly break it again).

Change #1
I removed two DNS Black lists from my sendmail.cf (later removed from 
the .mc file and rebuilt) as the sites are not responding (I suspect 
this may have been the root cause of the timeouts).

Change #2
Added OK statements to my access.db for my local domain as well as my 
local IP range

I am fairly certain that #1 is what corrected the issue as
1) I haven't ever needed the OKs before to eliminate delays
2) I can send as another of my domains (without the OKs) without delay 
now that the changes are in place.

Sorry for the OT post and thanks for looking at it.
