Hello,

Apparently my 3.0.6 fudforum is sending emails with duplicate From headers, it is rejected by gmail and others:

Our system has detected that this message is 550-5.7.1 not RFC 5322 compliant. To reduce the amount of spam sent to Gmail, 550-5.7.1 this message has been blocked.


Can anyone give me some pointers as to how to fix this?

What I've noticed is that emails are delivered if sent via mail(), but not if external SMTP is used.

Don't believe it's a fud software issue but a domain configuration issue, you may need to add a SPF statement to your record for google gmail to accept any of your emails..

Hi!

I can confirm that feature 'Use SMTP To Send E-mail' is unusable currently (v. 3.0.6).

Mails cause bans with error like the following:

status=bounced (host gmail-smtp-in.l.google.com[64.233.162.26] said: 550-5.7.1 [188.120.250.223      11] Our system has detected that this message is 550-5.7.1 not RFC 5322 compliant. To reduce the amount of spam sent to Gmail, 550-5.7.1 this message has been blocked. Please review 550 5.7.1  RFC 5322 specifications for more information. l73si6051874lfg.249 - gsmtp (in reply to end of DATA command))


This is the source fo the email sent using PHP mail() function:

Hello,

You have requested for your password to be reset. To complete the process,
please go to this URL:

http://vetusware.org/index.php?t=reset&reset_key=4a85e9e979b868e84c9f05ada88dc1d1

NOTE: This forum stores the passwords in a one-way encryption mechanism, which means that
once you have entered your password it is encoded so that there is NO WAY to get it back.
This works by comparing the encoded version we have on record with the encoded version of what you type into the Login prompt.
(If you are interested in how this mechanism works, read up on MD5 HASH algorithm)

If you received this message in error, please ignore it. If you are receiving multiple copies of this e-mail, which you have not requested, please contact the forum administrator at hostmaster(at)vetusware(dot)org

As you can see, there are duplication of several headers.

Okay I've managed how to fix that.

You need to remove the lines 138-139 from /FUDforum_home_dir/src/smtp.inc.t file:

                $this->wts('From: '. $this->from);
               	$this->wts('X-Mailer: FUDforum v'. $GLOBALS['FORUM_VERSION']);


(They cause duplication of the 'From' and 'X-Mailer' headers when using external SMTP-server.)

Then don't forget to rebuild your theme.

I've tested this fix with the inner mailer (PHP mail() function) also and everything works fine here.
