Send mail from our servers when using external mail
If you want to send mail from our mail servers but have mail services else where, then please do the following:
1) Add a subdomain called "mailer" to the domain via the control panel
2) Go to the mail manager for the subdomain and add a mailbox to send mail from .
3) Use the mailbox to send mail from scripts for SMTP authentication
4) If you use external DNS, you will need to add the proper records there for this subdomain .
------------
Please note that we strongly recommend that you use the mail servers
for the domain that you are sending for. The reason is a lot of mail
servers will filter mail otherwise and you may have to edit the SPF
records to allow the subdomain to send for the base domain.
