The IP address cannot be resolved. Either this address does not have a PTR record in DNS, or your resolver cannot obtain it.

Better you disable lookups in dbmail.conf by setting RESOLVE_IP=no

That will also improve performance because those lookups are synchronous and will therefor holdup the connection until the resolver obtains the name with an address or fails to do so.

Hello:

I have just completed a fresh install RH9 + mysql-4.0.21 + openssl-0.9.7d +
cyrus-sasl-2.1.19 + postfix-2.1.5 + dbmail_2_0_branch.

I have added a user (kbajwa) to dbMail DB. I can display the tables using
'mysqlcc' & user + aliases info is listed in the tables. I tried to setup a
connection to pop3 using MS Outlook Express. It works. However when I look
at 'maillog' on the mail server, I see the following error:

Sept 21 21:15:30 mail dbmail.pop3d[2575]: PerformChildTask(): incoming
connection from [12.21.237.250 (lookup failed)]

after this line, there are about 20-30 lines consists of SELECT & other
statements.  From the look of it, the logs show a successful connection -
confirming that I made a successful connection from Outlook Express.

My question is, what is the above listed error. Why does it says that the
"lookup failed" & how to fix it?

Thanks.
