For some reason, when I have a UNIX sendmail server send a message to my exchange server that is over 1095 bytes long, the connection resets with the following error: 'dsn=4.0.0, stat=Deferred: Connection reset by mail.domain.com' How can I get the Exchange server to accept messages larger than this size from the UNIX server? _____________________ Devon Harding System Administrator Gilat Latin America 954-858-1600 dharding@xxxxxxxxxxx <mailto:dharding@xxxxxxxxxxxx> This e-mail is intended for the above named addressee(s), and may contain information which is confidential or privileged.
