Dear List,
I recently spent some time out of the USA, and found myself in a hotel that blocked port 25 which prevented my laptop's ability to connect to my office mail server. I did a scan on the internet and made the observation that this was a common problem. I had port 22 available so I was able to get my office server set up to accept mail on 25 and 587 without difficulty. The command "telnet mail.server.com 587" to my office mail server connects without difficulty.
However, I have not been able to get sendmail on my laptop to connect to sendmail on my mail server at home using port 587.
I have added the following to sendmail.mc on my laptop without success :
define(`RELAY_MAILER_ARGS', `TCP $h 587') define(`ESMTP_MAILER_ARGS', `TCP $h 587')
I finally made it back home, but have decided to change my configuration to use 587 by default so that this problem will be avoided, but I have been unable to get my laptop to connect.
Anyone having ideas would be appreciated.

Everyone,
Thank you for your assistance; the best solution seemed to be the use of openvpn, or changing to thunderbird instead of evolution. I never found a method to make sendmail send mail out on 587.
However, I did find an easy solution for evolution to use smtp on port 587. I will record it here so that anyone looking for this in the future will have the right methodology.
All I had to do was to place the port number after the server name in the "Sending E-Mail" tab of the "Preference -> Mail Account module in the form of :
mail.domain.net:587
It was easy to set sendmail up to use port 587 with the entries :
DAEMON_OPTIONS(`Port=smtp, Name=MTA')dnl DAEMON_OPTIONS(`Port=submission, Name=MSA, M=Ea')dnl
Please note both entries are required for sendmail to use port 25 and port 587.
Thanks again for everyone's help!!!
