Have some large databases about a mil from each yahoo and hotmail and about the same from various others combined.

LMP is working great - in fact congrats, nothing simpler to use.

Problem I am having is that yahoo is not accepting any mail from LMP at all. I can send messages to yahoo from any domain, address even the one I have LMP installed on. They all get through - except from LMP itself. Therefore the IP address has not been blocked at all. I change the to, from, bounce ID's and even use other domain email addresses but still no go. It is therefore LMP specific - Any ideas?

TIA - Paul

Ok, there is an addition to the headers of every email that states:

X-Mailer: ListMail v1.xx

This could be used for mass blocking.

In admin.php, remove or comment out (precede with //) the 3 lines matching the following:

$header .="X-Mailer: ListMail v$ver";

If you experience notable success let me know and I will remove this header immediately as it could be causing problems for other users.

Will let you know. I simply changed the header to something else as sometimes these things can be tricky - the headers MUST have all the info or that can be a cause to get blocked as well. Have seen that in very ordinary other programmes.

Did exactly as you suggested but still no joy there. Even changing the header as I stated above did not work. Any other ideas?

I have a dedicated server with several sites on it. Am happy to install LMP on another site to sort out if site specific if you think that would be an idea.

Check out your MTA (qmail,exim,sendmail,etc) config and see if there is an option to increase the max load for the queue. Changing an option like this helped another client of mine who was experiencing similar issues.

Don't forget to restart the software once you have made the changes to the config file.

That what you mentioned will assist in other areas and possibly with an upgrade to an updated mysql engine as well.

I use another programme called phpmail on two of my sites. It is an excellent programme from www.phpmail.com. I am actually a moderator on that forum. The programmer there - 'Beer' is a very clever man and I posted this on the forum as I have a similar problem there. This is what I posted...

I mentioned briefly on MSN messenger to you about yahoo mail problems not getting through with another programme I am using.

The same thing is happening with the two installations of phpmail I am using.

What is interesting is when I use squirrelmail on cyber-mailer.com all messages to yahoo get through. Therefore we are not looking at an IP issue or anything else.

It seems that yahoo has really put the clamps on with email headers etc. This clearly now affects phpmail.

Hopefully this will clarify issues. Cyber-mailer is in fact where the LMP installation is. I downloaded and installed two other mass mailer programmes but the result was the same - mail not getting through to yahoo. Squirrelmail works well though.

BTW - I am on a www.valueweb.com ensim dedicated server.

I even did a naughty thing for testing purposes and changed the header around a bit. Instead of 'X-Mailer' I put:

$header .="User-Agent: Microsoft Outlook Express 6.00.2900.2180"

That was just to test for an inclusory issue as opposed to an exclusory issue that we looked at.

Sadly - was not to be. Test failed.

The interesting thing here is that I have a large Cyber Dating site on the same server - and messages yo yahoo are getting through.

OK - made some progress... Of a kind.

Using the SMTP mailer it works fine to yahoo.
Using the PHP (imap) mail function it does not.

There-in lies the difference - the problem and a solution.

Notification, welcome, and confirmation messages are all sent with PHP mail(). It's possible your server is not setting the bounce path correctly and Yahoo is detecting it.

Try uncommenting or adding the following line in config.php

$phpmailf = 1;

This will add a 5th directive to the PHP mail() function which tries to force the return path to be correct.

This is not done by default because it can add an additional header to your messages:

X-Authentication-Warning:

To avoid this message you must enter the Apache username as a "Trusted User" in your mail agent. This problem / solution might only apply to Sendmail.
