IMAPd in Logwatch

[IPaddress]

Hi!
Im running Directadmin 1.33.2 on a CentOS 5 Final.
Looking my LogWatch ive notice some strange things the last few days...

--------------------- IMAP Begin ------------------------
[IMAPd] Logout stats:
====================
User | Logouts | Downloaded | Mbox Size
---------- | ------- | ---------- | ----------
??? | 7 | 0 | 0

**Unmatched Entries**
Connection reset by peer, while reading line user=??? host=UNKNOWN: 1 Time(s)
Logout user=??? host=UNKNOWN: 1 Time(s)

---------------------- IMAP End -------------------------

I'm a little worried about who the hell is "???" cause looking to my logs i couldnt find anything strange.
And as you can see, the logwatch didnt give me anything information about "???".

What can i do? Is this something to be worried about?

Thanks in advance.

Bye!

PD: Sorry for my poor english, im from Argentina.

Most likely your log is reporting on some kind of attack. Logwatch simply tells you something is going on in your logs. You need to actually check the log to see what's going on.
