It seems you have a misunderstanding of the "retrieve messages left on
the server again" option of PowerMail. It will re-retrieve messages that
Powermail has already retrieved on this account, but not deleted from
the server. It has nothing to do with the "read flag" that gmail has on
the server side, as this notion is not part of the POP3 protocol. Gmail
does not know which messages have been downloaded by PowerMail. This
option should only be used in some special circumstances:
- messages are identified on the server side by a unique ID, but there
may be some rare circumstances were some POP server re-use a (not-so)
unique ID for a different message; in this case, PowerMail could miss
some messages, thinking they have already been downloaded. In this
situation, if you have configured PowerMail to *not* leave messages on
the server, you can enable the "retrieve messages left on the server
again" to be sure that no message will ever be missed.
- if you have accidentally deleted some messages, and want to re-
download them. In this case, however, you will get duplicates for
messages still present on the server and locally.

The STARTTLS command is normally used on the standard ports (port 110
for POP, 143 for IMAP, 25 for SMTP). When using special ports (995 for
POP, 993 for IMAP, 465 for SMTP), the STARTTLS command should not be
used; check "use a dedicated secure port" instead.

No, I have not.

Which is what I expected.

I know this. Obviously, the 2nd result I got with a new clean
environment can be explained with the interplay with this gmail "flag"
function as I had already tried to get messages to the old DB.
Nevertheless, I still had problems in my third attempt, after I had set
all messages to be available to POP in the gmail web interface. See
separate post.
>Gmail does not know which messages have been downloaded by PowerMail.
It states it knows which have been downloaded via POP. Before I tried
with Mail now, there has been no other POP-client accessing my gmail account.

The problem is I get up to 10-15 duplicates resulting from the same
session. This is not unique PM behaviour and have been teh case with
several other accounts. While this behaviour may prevent messages
getting lost, duplicates still are a nuisance.

After I had Enabled "POP for all mail (even mail that's already been
downloaded)" in the gmail web interface, I was able to redownload up to
about 3660 or so incoming messages out of 4000+ on the account. About
600 of these are outgoing so the numbers don't add up really.
Please keep in mind that prior to trying with Mail some days ago, no
other client have been downloading my new messages. So nothing like that
can have affected that gmail have not given me messages since sep 13
2009 on this account.
Day-fresh messages are now downloaded, which is great and is what I
wanted. Unfortunately, other recent messages seem to have been lost.
Because of the nature of Gmails interface it's hard to tell what the
differences between messages are, there just are gaps, however small.
This do seem like a repetition with the earlier experience with gmail
and PM not agreeing on what have been downloaded or not. It seems google
won't give active support with PowerMail as a client unfortunately.
I also had many many of these messages arriving as duplicates, seemingly
because of prematurely abrupted connections where PM keeps asking again
and again for a specific segment until it have all messages within that
(a guess, have not observed in detail), even if a particular message
actually already is in the DB. It is possible this could be an interplay
of gmail only giving 600 or so messages at at time and the "get
remaining messages" setting in the account settings, but turning this
off after the first connect didn't seem to affect this problem.
I had up to 10-15 duplicates of some these messages. I deleted a
majority of those duplicates with a script of mine, that compares the
headers between the messages and leave only one copy in the DB.
I can't rule out at the moment that my script didn't delete the missing
messages, even though I have never observed non-duplicates being deleted
before. It could also being something else interfering. I will look into
that later.
Currently it's hard to deduct exactly what's going on and I have other
more pressing matters to attend at the moment. I'll send CTM an empty DB
and see what they can find regarding getting all messages and hopefully
also this matter with duplicates.
