POP3 and "seen" flag

[Miki Tebeka]

Hello All,

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

Thanks.

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.

Hello Peter,

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.

That the message have been read (RETR executed on it). The "seen flag" is
taken from 'retr' documentation at
http://docs.python.org/lib/pop3-objects.html.

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

Good to know

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.

No such luck for me.

Message-ID header, but something tells me you are interpreting "seen" as
meaning "anyone has RETRed the message", so that won't work either.

You're right.
I'm trying to delete only read messages from Exchange server, *another*
client is used for reading. (It's a long story involving me and IT here
...)

Bye.
