Solution was to edit /etc/mail/sendmail.mc to add RELAY_MAILER_ARGS and ESMTP_MAILER_ARGS with the correct port number and then to use the '-r' option of mailx to fake out the sender to an legit address (in my case, using same address as who I am sending to). Never got to the issue of dealing with multiple port numbers for different emails as I only needed the one to get from my 192.168.2.x LAN to pnewell@xxxxxxxxxx Thanks to everyone on this list who helped me sort this one out, Paul -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
