| That probably won't work, somewhere a firewall is preventing OUTBOUND
| connections to port 25, this is a common practice these days.
|
| What you need to do is:
|
| 1) Edit /etc/mail/sendmail.mc and uncomment line 22:
|
| dnl define(`SMART_HOST',`smtp.your.provider')
|
| by deleting "dnl". Replace smtp.your.provider with the correct
| smarthost for your network.
|
| 2) Stop and restart sendmail (as root):
|
| /sbin/service sendmail restart
|
| All the mail in the queue should now be sent, this might take several
| minutes, and future emails should work as well.

Problem solved.
Many thanks.
