I am very impressed with your helpfulness. Unfortunately the search
program Remove Duplicate Messages doesn't work with my configuration,
neither with Seamonkey nor with Thunderbird. Finding the cause won't
be easy, since I use 3 Windows and 3 Linux systems each. Many thanks
for the corresponding hints.
I use pop3 but I can't exclude that I already experimented with IMAP
on a computer. Maybe I will follow the advice to delete the mails
manually, but with 4000 mails a lot of work.

Yes, I have a lot of two copies of one email in the 'Sent' folder.

Is your 'Sent' folder on an IMAP server?
If so, it might be that both SeaMonkey and your mail provider are
both storing a copy of emails you send there. If SeaMonkey is
configured to store a copy there (under Mail & Newsgroup Account
Settings), it would do so when you send an email from SeaMonkey.
Some mail providers put a copy of emails you send via their outgoing
(SMTP) server in a 'Sent' folder. So if both are storing a copy in
the same folder on an IMAP server, you'd end up with two copies of
every email you send from SeaMonkey Mail via their outgoing server.
You could disable SeaMonkey storing a copy for that account, and just
rely on your mail provider saving emails you send in your 'Sent'
folder. But then you might not get a copy saved if for any reason
you send an email via a different outgoing server (may not be a
concern if you never do that). You'd also be relying on your mail
provider continuing to store a copy - if they stop doing it, you
wouldn't get copies saved until you notice and re-enable SeaMonkey
storing them.
Your mail provider might also provide an option to disable saving a
copy from their side. But then you might not get a copy saved if you
use webmail or a different mail client (again, may not be a concern
if you never do that).
