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 no-reply@mydomain.com"

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?

Make sure to enter a return address in the from settings, especially if the from address is a dynamically generated address form the form.

Either the from Address or the Return Address must be a valid email address on the SMTP servers domain.

Origination and X-Mailer are optional headers.

Organization is Organization to which the sender of this article belongs. Mostly used for company emails

X-Mailer is the program used to create the message. In this case it should be PHP Script, but again it is optional.

Anyone have any idea how to get rid of that 'on behalf of' which identifies my hosting server, rather than the companies domain?

On the mail server settings page of universal email, try checking the option to include the from address as an extra parameter.

No luck with that setting, still show as shown "on behalf of" my client by my server.

Interestingly when I look at an email sent by your automated newsletter system it doesn't show up as 'on behalf of' even though it comes from a different domain (topica.com.)

So there must be some way around this.

This is added by your SMTP server. Are you using GMAIL? I don't think there is any way around it other than setting up your own SMTP server or using one that doesn't add this.

We don't do anything to remove it, we just use an SMTP server that doesn't add it.

Nope, not gMail.. It is my hosting provider, so I'll ask them.

Out of curiosity... who is your hosting provider?

Contact me by PM or email and we can discuss. :)
