Why sendmail injects into postfix qmgr?

[bzzik]

Dear all,

I have noticed some strange things in the maillog:

As you can see for some reason sendmail is trying to do something with the incoming email. Why?

P.S.
I am running CentOS 5.4 with ISPConfig 2.2.29 installed using the Perfect Setup tutorial.

[till]

This is the process that creates the email statistics. The sendmail process creates a message to the script called "admispconfig" which contains the size of the received message and the admispconfig script then creates the statistics that you see in the ispconfig interface for this mailbox.

Oh, I see now. I thought that it is some problem or may be something is trying to hack

Can I ask you, is this normal that there is also TLS/SSL problem?
