seems like a too long Subject may be one reason.
i tested long lines in the body and long subjects:
- body line with 20000 chars is no problem for mailin06.sul.t-online.de
- subject with 16373 chars is no problem for mailin06.sul.t-online.de
- subject with 16375 chars is rejected with "500 5.6.1 Line too long."

but i doubt that people send mail with subjects > 16373 characters. so
there may be other cases, where the t-online mailserver responds with
"500 5.6.1 Line too long.".
my tests also showed, that courier for example rejects any mails with
subjects longer than ca. 4990 lines.

the problem is that newsletters are sent through this server, and some
of them have more than 50 t-online addresses subscribed. and for some
reason the error happens quite often.
i will see whether i can get one of the mails that produced such an
error. but the error occurs only for t-online addresses, all others
receive the newsletter.
