Greetings All,
Question for the group: I have encountered a situation that causes me to believe an ISP is snoopingthrough encrytped mail. It seems that PGP'd mail has aroused the curiosity of an ISP (not hooked.net).. I have encountered "POP3 account in use by another user" several times in the past few days and I am the only user... wondering if that "in use" messsage is the result of a clumsy sysadmin being caught with his hand in the cookie jar. Any thoughts from the group??? If those more knowledgeable than I deem these NOISE... my sincere apologies.
An admin could just copy the mail spool file to a safer place, then read through at their leisure.
Unless its someone totally clueless (which some ISP's are), I doubt that they are pulling off the pop3d. It could be that your mail spool file is locked by a mail transport agent, and that is why that error message is occuring.
Any thoughts?
This is probably somewhat system dependant, but I'm guessing that any lock on the file "could" generate the message that the account is "in use." Could be a lock which was not cleared from a previous session, a backup system that wants exclusive reads on the files, etc., not necessarily another POP3 session. As for the sysadmin side, yes, there are other, easier methods of getting at the mail file. OTOH, could be someone inside an ISP (or not), who does not have access to the file structure, but did somehow obtain passwords through other means. Any ISP of any size will have different levels of access for different employees, and the graveyard helpdesk shift can get fairly dull ... It is more than likely a system-related problem with a file lock, though. I'd suggest changing your password, and making sure that you don't use a dictionary word or obvious permutation thereof. If you continue to have problems, check with the ISP about your "technical difficulties", and see what they come up with. Just my $.02 - r.w.
