Answer/Solution: IMonitor is monitoring the SMTP service. As you can see it
happens every minute, the interval you have set in IMonitor. IMonitor tries
to connect to the SMTP (or other service) each time it polls the services
(from the localhost address, 127.0.0.1). If the service is recording to the
log, that connection is then entered in the log. The port number is
incremented for each connection. Since this sequence shows non-consecutive
numbers, there are other connections to the SMTP service between the
connections caused by IMonitor (probably sending and receiving of mail). 

The number after SMTPD (such as, 159F0140) is a sequence number IMail
assigns to each new process (connection). This allows you to track all the
operations of that process.

Subject: [IMail Forum] Help interpreting log file entry...

Hi

Hopefully a simple question.  Was looking at the syslog file for some 
other reason, and noticed loads of entries like this...

12:05 16:43 SMTPD(017500E0) [212.135.236.109] connect 212.135.236.109 port
4801
12:05 16:44 SMTPD(017600E0) [212.135.236.109] connect 212.135.236.109 port
4807
12:05 16:45 SMTPD(017700E0) [212.135.236.109] connect 212.135.236.109 port
4813



Wondered what the server is doing - it looks like it is port scanning - 
and whether it should be doing so?

Regards
