SMTP 502 Error - Email Problem

[DotVince]

We seem to have solved it.
Our IT department had to change the relay settings on the Exchange server, it turns out that relaying was only allowed for a set list of IP addresses.

I would still be interested to know if we can modify the config so that all DP generated emails come from a particular address.

Best wishes,

Line 401 of classes/libmail.class.php

	$this->socketSend("HELO " . $this->getHostName());

I guess you can figure the rest out.

Thanks Pedroa, but I'm not a coder - just copy and paster

$this->socketSend("HELO [XXX.XXX.XXX.XXX]");

Sorry man but I just don't know what IP you let me put there on the XXX.XXX.XXX.XXX, so ask your IT department. Oh, don't forget, the brackets should be there too.

Update, in case useful to others:

1) Change line 401 from:

$this->socketSend("HELO " . $this->getHostName());

to:

$this->socketSend("HELO " . "[internal Exchange server IP number]");

2) Change line 426 from:

$rcv = $this->socketSend("MAIL FROM: <$from>");

to:

$rcv = $this->socketSend("MAIL FROM: <projects@ourdomain.com>");

3) Change line 160 from:

$this->xheaders['From'] = $from;

to:

$this->xheaders['From'] = "projects@ourdomain.com";

And that apparently does the trick. Anything we missed?
Thanks for your guidance.

May I suggest that DP should have an admin option to do this so as to avoid the issues with 'spoofing' external email addresses?

Best wishes,

Great. That fixed my problem with SMTP auth.

I think my hastily set up server is misconfigured somewhere and as a result any dp emails appeared to be coming from a different (local) domain (my email is hosted with an ISP different to the one I use for access and different to the dp server installation).

Anyhow, I was getting a message 500 back from my ISP complaining about mail address appearing to come from a different domain. No complaints now.
