Hi Carlos,

is there anything accessing the mailboxes at the same time, for instance
another e-mail client (thunderbird, kmail, evolution) that is also
deleting messages?
Fetchmail is downloading and marking 20 messages as deleted, issues
"EXPUNGE" and the server reports 21 or more messages expunged, which
confuses fetchmail (meaning: nobody has written code to deal with
something else accessing the mailbox at the same time).

If you are 100% sure fetchmail is the only client accessing the server
at the same time, then file a report to the server's operators,
otherwise, the workaround would be to not make fetchmail delete messages
so it doesn't expunge either.

The relevant source code comment is:

>      * reports the wrong size to the SMTP server on MAIL FROM: and
>      * triggers a "message ... was not the expected length" error on
>      * every subsequent mail */
