Getting your emails through the SPAM filters?
Interestingly when I did my first few attempts at sending email through (to myself) using only the "mail" option with no SMTP server or Port information the emails made it all the way through to my Inbox without issue.
These emails came through with the From Field reading:
"accountname@hostingserveraddress on behalf of firstname.lastname@example.org"
In an attempt to get through the 'on behalf of' part of that I installed Pear on my testing server and Authenticated into the SMTP server. With a correct From Field these emails went directly into the SPAM folder.
It should be noted that I did use a different Subject and Body on every message that I have sent.
I also tested sending the exact same emails that failed from another one of my accounts (via Outlook) and they passed through without hitting the Junk mail folder.
Anyone have any idea why this would happen or how to get rid of the 'on behalf of' using "mail" ?
Also, while we are at it, what are the Organization and X-Mailer headers used for? I really can't find a lot of useful information on them. Are they useful in any way, otherwise why are they there?
