Errors delivering message

Hi,

I am currently trying the test_smtp_message.php script with supporting files email_message.php, smtp_message.php, and smtp.php.

With the current params, it seems able to easily make the connection to my smtp server, via pop3 or through a direct connection to the recipient's smtp server, but in all cases the message cannot be ultimately delivered.

When sending through my authenticating outbound mail server, with or without POP3 auth, I connect, but get an empty error:
Error: +OK CommuniGate Pro POP3 Server ready

When sending directly, I get an invalid recipient error, even though the the recipients I've tried are absolutely valid:
Invalid recipient: paul@mydomain.com Error: +OK <22938.1258165690@mydomain.com> Error: it were not specified any valid recipients
(where "mydomain" is a valid personal domain)

I have tried just about every combination of variable, from direct, to tls, to pop3, etc. Anyone have any hints on how I can go about figuring out why my messages are not getting delivered?

Thanks

Paul G

I doubt that you really need POP 3 authentication these days. That was just for old ISP systems that did not support SMTP authentication.

The message clearly says that you did not specify any valid recipients. It means that the recipients that you specified cannot be mailed by the current server for the current user.

This may happen if you did not specify an valid SMTP user and password. That should be done using the user and password variables of the class as you may see in the example script.

Thanks Manuel.

I double checked my smtp user and password, and they are correct. when using pop3 auth, it successfully echoed back the number of messages I have on the smtp mail server, proving the combo must be right.

It's the same combo that I use for my email account in Mail.app on Mac when connecting to the same outbound mail server, using the same port (110)

But I just tried port 25 and got some more messaging (shown at the bottom of this post
), but still no sent message!


Here is what I am working with... (some data changed for security reasons)

Error: server does not require authentication

// note... when TLS is set to zero, it suggests it be set to 1

Just because POP3 authenticate successfully and it returns how many messages you have in your mailbox, it does not mean that you need to do POP3 authentication to be able to send messages. It does not hurt doing it, it just may be a needless step.

Anyway, if starting TLS returns a response saying your SMTP server does not need to authenticate, that means that you do not need to specify an user and password to authenticate. So try setting the user and password variable to an empty value and remove the POP3 authentication option.

BTW, although this may not be your problem, the recommendation is that you use the SMTP class in conjunction with the MIME message class, as it is the way to go to compose e-mail standards compliant messages.

Thanks again.

I just tried it without a user name and password, and it worked!

I would never have guesses that was the problem. Thank you.

I'm having trouble understanding why my desktop email client requires a u/p and port 110 to send outbound email, and your script requires no u/p and works on port 25?

Is it because I am sending the message from a server that is operated by the same company?

Appreciate your help.

Great script. I tried 4 others before yours and gave up on all of them.

Regards,

Paul

Maybe. Keep in mind that your desktop client also pulls e-mail from a POP 3 server, so that may be the only reason why it needs to access the POP 3 server.

Well... I'm _almost_ home!

Turns out, having gotten back to this project, that while the mail is in fact sent via SMTP (80% of the battle), the headers appear to be misinterpreted or somehow malformed.

The context of my problem, is that I am trying to automatically send list commands to a list serve.

The list serve (DLIST), is looking for the command in the body of the message, but instead it finds a "From: " header and so aborts the process. Could it be that something is not being encoded properly?

Here is the script output (edited for privacy), followed by the DLIST message. Hope you can tell what's wrong here.

----------------- and here is what I receive from the request at the address
as you can see, there is some odd encoding around the sender address and the "From: " header has slipped into the body content. Thoughts?

one other item...

the responses are failing the SPAM test. I think this will resolve itself once the header issue is resolved. But, just to be thorough, the server is complaining about:

0.01 INVALID_DATE Invalid Date: header (not RFC 2822)
1.58 MISSING_HEADERS Missing To: header
1.76 INVALID_DATE_2 Invalid Date: header (not RFC 2822)



Paul

and... yet another note...

the mail headers suggest that
"Note: you may have to turn off 'html/mime' formatting before posting a command."

Is that relevant to this script?

It seems the body message is malformed.

You need to use the MIME message class to compose and send messages in conjunction with the SMTP class for composing and sending correctly formed messages:
