If you block telnet access, then you're blocking all SMTP traffic to that host. The server has no way of telling that you're using a telnet client instead of an MTA. If you don't want to receive e-mail on that server, just shut sendmail/postfix off. -- Ed Wilts, Mounds View, MN, USA mailto:ewilts@xxxxxxxxxx Member #1, Red Hat Community Ambassador Program -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
