Hello,
Has anyone been having any issues since last week with the reverse DNS lookup
connection filtering option?
I have had large numbers of false-positives reported from our users, and for
almost every one when I do a reverse lookup on the mail server manually, I get
a response. It seems iMail, for whatever reason, is not working.
I also did the same reverse lookup on the DNS servers specified in the iMail
SMTP settings, and it worked there as well.
Anyone know of any issues with reverse DNS in iMail? This seems to have
started after we deployed 8.14 last week, but I'm not sure. We've used
revlookups for many months previous to that and didn't seem to have a problem
with reverse lookups failing on IPs that do indeed have PTRs.
Thanks, and Happy Holidays!
