Thank you Peter - thinking about it, I must admit that at that time the
line must have been pretty choked (time to send some 2K emails each
about 70KB in size). This could have made it difficult to properly
connect and send data to o2.pl. I know exim behaved as expected under
given circumstances. To my knowledge o2.pl does not use any greylisting
(at least none that I am aware of). Could the reason be bandwidth
problems and would/could limits in bandwidth use help me avoid such
issues in future? Or is it the fault of the o2.pl server?

Thanks!
