mail send problem and solution

Problem:
I am having trouble setting up the webmail. I can log in to ehcp webmail with the correct user name but when I go to send an email, I do not receive it to the test email account I where I sent it. Do you have a troubleshoot list for setting up the email server?

Answer1:
check your syslog by tail -f /var/log/syslog
on your command line, while sending your email. that will help you
resolve issue.. you may also send output to me.

to which email do you try to send email ?
try to send out to gmail for example..

Reply and solution:
Hi there, I checked the syslog and it was timing out. Turns out that my ISP filters port 25. I had to change a line in the etc/postfix/main.cf file to:

relayhost = smtp.yourisp.com

It worked after that.

Thanks
