Re: POP3 and "seen" flag

Is there a way to know in a POP session of a message was seen (old) or not

Define "seen". It could be interpreted as either "TOP" or "RETR" having been executing for a message, or something like "this client has seen this message before" ... not sure what you mean.

In any case, the short answer is "no".

The longer answer is that _some_ POP3 servers provide non-standard support for this by doing things like adding a special header to the message, things like "X-Seen", which can be seen by using the TOP command. This sort of thing is entirely non-standard and you can't rely on it in general, AFAIK.

A better approach would be to have your client software track the Message-ID header, but something tells me you are interpreting "seen" as meaning "anyone has RETRed the message", so that won't work either.
