After a very reasonable request for my setup and "-vv" output from Matthias Andre, here it is. Note that after failing on message 1 (containing the _ in sender domain name), no attempts are made to fetch message 2 nor process the next account.
I emailed myself an email from "[EMAIL PROTECTED]" using Evolution 2.2.3 and then did "fetchmail -vv >file1 2>error". <user> and <pw> are masked.
