There’s obviuosly some sort of limit going on, but I can’t find it anywhere - my sendmail config is very basic (just using the yast parameters) - can anyone point me in the right direction?
As far as I know there is no such limit as 2500 lines for the message body in sendmail. This is very strange. Can you post the relevant line(s) from the logfile /var/log/mail showing what it did when receiving the message?
