Should I be concerned?

[PoserAdmin]

Hello,

For some reason (a post in another area while researching this http://discussions.apple.com/thread.jspa?threadID=1438597&tstart=0 issue prompted this), I was looking in /var/spool/imap and found a listing of folders that had names that match or partially match non-exsistant spam recipients on my server. Meaning names that keep showing up in the mail queue that are not actual users on the server. Here is the list from the folder:

drwx—— 5 cyrusima mail 170 Feb 21 04:06 ^_-cyou
drwx—— 5 cyrusima mail 170 Feb 21 01:48 ^_-e-link
drwx—— 5 cyrusima mail 170 Feb 21 05:25 ^_-ericcrowder

drwx—— 5 cyrusima mail 170 May 9 2007 ^_-zalapomuciamux
drwxr-xr-x 2 cyrusima mail 68 Mar 12 07:23 stage.
drwx—— 17 cyrusima mail 578 Nov 1 2006 user

Most of the folders with the ‘^_-‘ in the name are spam recipients and not users… What does this mean?
