how to change port in sendmail in fedora

2006-10-21 2:12 am

I have a server using Fedora FC5. It has sendmail 8.13.7 installed.
The problem is my ISP blocked port 25. I can't send any mail from the server. I got a message "Deferred: Connection timed out with mail.xxxxx.net."
I have read some articles said the problem is possible to be solved by changing the port from 25 to 587.
Q1 How to setup the sendmail.
Q2 Could I use the other smtp such as gmail. It is ok if the return address is fixed.

Below the dnl define(`SMART_HOST', `......') in /etc/mail/sendmail.mc, add the following lines:

define(`RELAY_MAILER_ARES', `TCP mail.xxxx.net 587')
define(`ESMTP_MAILER_ARES', `TCP mail.xxxx.net 587')

beware RELAY_MAILER_ARES, ESMTP_MAILER_ARES and TCP ..... 587 should be start with the single quote on ~ Key (about the Tab Key) and end with the normal single quote (on the double quote key beside ENTER key)

After edit the file, type make under directory /etc/mail and then restar the sendmail with /etc/init.d/sendmail restart

You can try Gmail, but I suppose need to use SMTP AUTH and SSL/TLS to connect gmail. Refer http://www.sendmail.org/~ca/email/auth.html and http://www.sendmail.org/~ca/email/starttls.html for the detail description.
