Hi Matthias,
Seems the problem you are referring to is caused by fetchmail not
being able to delete the message, in the beginning for me it just
downloaded one message and then started complaining about message size.
Because of this I've just added the keep directive to fetchmailrc, which
looks like this now:
poll imap.next.mail.yahoo.com with proto IMAP
user '************' with pass "********" is '*********' here
options ssl smtphost localhost keep;
This configuration has worked fine for me for over a week.
As for the server, it seems you can use *imap.mail.yahoo.com* as well.
PS: Sorry about the spam, but Thunderbird 3b2 really sucks at replies :-)
Best Regards,
Valentin
