Send Email out Finally

Finally, i use postfix to relay mail to another server

i use

relayhost = [other.host]:587 and mail server works perfectly on postfix.

don't forget to add ip address into other host server otherwise they will not refuse to send your email. :)

this is great example.

other server using exim (cpanel) and i use their function to add trusted server ip address into list.

now i want to use sendmail instead of postfix. keep searching and found this:
