I don't know of any dialup service that limits bandwidth, so I doubt you
are paying for those packets.

Edonkey, like other P2P networks, downloads files from many users at once.
 If you quit edonkey, then start it up a week later (with unfinished
downloads), it naturally queries the last contacts for that download. 
This is probably what is happening.  

You shouldn't be any more upset with these port 4662 hits (now that you
know they are non-abusive) that you would be with port 80 or 25 hits. 
Lots of dialup users run their own mail or web servers as well.

It's a non issue.
