My ISP imposes SMTP restrictions on outgoing mail, is it possible to configure a system wide SMTP address to use, instead of having to configure each mail client individually?

This worked for me:

  • Open up /etc/postfix/main.cf
  • Replace relayhost = by relayhost = relay.your-isp.com where relay.your-isp.com is your ISP's SMTP server.
