FreeBSD mailing list reverse DNS problem

[Ihsan Junaidi Ibrahim]

Hi all,

I was equally stumped by the problem as well. After trying so many solutions, 
for some reasons, which I'm not too sure was when I asked my ISP to increase the 
TTL information from 1 hour (1H) to 1 day (1D), it immediately worked. I no 
longer have problems sending mails to this list (including this one).

I'm not a DNS expert but for the life of me I can't see the correlation between 
a TTL and reverse lookup.
