I have switched over to Google Apps so that I can make use of Google's mail server. Everything is working fine. When an email is sent from any email account it arrives in my Google account.
However, whenever a user uses my site to send an email to me; I make use of PHP to send the mail. The mail arrives in my old inbox (squirrelmail) which is installed on the server. It doesn't seem to go outside of the server network, its probably looking at something listed within the server.
My domains DNS settings are elsewhere and not on the server.
I have sendmail installed and I think qmail is acting as a wrapper because of Plesk. I have removed Plesk since then.
I hope somebody has made sense of the above and can help!
Thanks all for any help on this
