Could it be a timeout issue because of some network failure?

Subject: [Declude.JunkMail] strange DNS failures


First the backround ... Imail 8.01, Declude 1.75i2, WinXP
Professional, Simple DNS 3.20.02

IN the past week, I've noticed the occasional REVDNS and SPAMDOMAINS
failures ... when I look, the tests are positive because Declude is
not getting a reverse DNS PTR record on the IP, and fails the test
thinking the IP doesn't have a PTR record.

But when I go to simple DNS, and look in the cache, the IP and PTR
record are there ... they are being lookup.

I then go to a workstation away from the Imail server, point to the
DNS address, do a PTR lookup on the record, and the correct PTR record
is returned.   So it appears that Simple DNS is looking up the PTR
records correctly, and will respond to an inquiry about them.

As I said, it is not always happening ... noticed two false lookups
this afternoon, but records were present.

To possibly help the issue, I put the DNS statement into Junkmail
global.cfg file so Junkmail has no excuse not to find the DNS server.

Any other ideas?

David

That is unusual.  Declude JunkMail should only fail the REVDNS test if it 
does get an answer from the DNS server, which says the reverse DNS entry 
does not exist (if there is a timeout, it should not fail the test).

If this happens often, you could use the DEBUG mode (LOGLEVEL DEBUG), 
which records more details about the reverse DNS lookup in the log file.
