Ladies and Gentlemen:

At the risk of double posting . . .yet again (sending this time in plain 
text format), I'm reposting this question -- apparently my previous 
membership was purged or otherwise not valid.

Regardless, after about eight months with no problems, AT&T U-verse has 
once again quit resolving? my reverse DNS; and now I can no longer send 
eMail to DNS-aware MTA's, such as,,, 
et al.  I have tried tweaking my zone file as follows but nothing seems 
to work.  I think they (AT&T) have done something . . .yet again, to 
block my DNS server (authority?).  Regarding my zone file configuration 
follows.  Can someone tell me if the configuration is erred, and 
otherwise suggest corrections, or should I expect it to work? . . .and 
pressure AT&T to fix the problem.
