[IMail Forum] Help interpreting an odd log file entry

[Wolf Tombe]

Traditionally my log files have averaged about 5 Mb a day.  However, starting May 11th they jumped to approximately 35-40 Mb a day.  In reviewing the logs I’ve noticed a huge amount of odd entries which appear to be coming from one of my own IP (64.32.172.145) which is running a client’s website, Unfortunately, I’m not sure how to interpret the log entries themselves.  I’m pasting a snippet from the logs here and would appreciate any help in understanding what exactly it is telling me.   Thanks!   20030511 000000 127.0.0.1       SMTPD (0A020122) [64.32.172.135] connect 64.32.172.145 port 2084 20030511 000000 127.0.0.1       SMTPD (0A020122) [64.32.172.145] EHLO whitewolf 20030511 000000 127.0.0.1       SMTPD (0A020122) [64.32.172.145] bogus address in MAIL FROM:<> 20030511 000000 127.0.0.1       SMTPD (0A020122) [64.32.172.145] bogus address in MAIL FROM:<> 20030511 000001 127.0.0.1       SMTPD (0A030122) [64.32.172.135] connect 64.32.172.145 port 2085 20030511 000001 127.0.0.1       SMTPD (0A030122) [64.32.172.145] EHLO whitewolf 20030511 000001 127.0.0.1       SMTPD (0A030122) [64.32.172.145] bogus address in MAIL FROM:<> 20030511 000001 127.0.0.1       SMTPD (0A030122) [64.32.172.145] bogus address in MAIL FROM:<> 20030511 000002 127.0.0.1       SMTPD (0A040122) [64.32.172.135] connect 64.32.172.145 port 2086 20030511 000002 127.0.0.1       SMTPD (0A040122) [64.32.172.145] EHLO whitewolf 20030511 000002 127.0.0.1       SMTPD (0A040122) [64.32.172.145] bogus address in MAIL FROM:<> 20030511 000002 127.0.0.1       SMTPD (0A040122) [64.32.172.145] bogus address in MAIL FROM:<>
