Issue psa-pc-remote: Incorrect recipient mailname

[Barungar]

Hi,

I've a problem with sending mail from a php-based forum software. The mail is send via smtp, delivered to port 587 using a user/password login. The forum software sends the mails in formated address style: User-name <[email protected]>

Every Username that contains certain characters is rejected! So far I have identified "-" and "\" for being rejected. The characters occure in the user's name, not in his smtp address. The user in question is "a-bulas" so the formated mail should look like "a-bulas <[email protected]>".

The issue is noted with "psa-pc-remote[21388]: Incorrect recipient mailname : a-bulas" which then results in "5.7.1 Command rejected". Where is the root of my problem? And what can I do to resolve it?

Generally mails are send and delivered without any issues, only if some characters occure in the user's name this issue arises.

Below is part of the /var/mail/maillog:

And help or hint is appreciated!

Hi Barungar,

Every Username that contains certain characters is rejected! So far I have identified "-" and "\" for being rejected.

Actually, the notice "Incorrect recipient mailname : a-bulas" indicates ( and you state this as well ), that your script passes over a wrong format, where only the username can be parsed and the correct usage is to pass over the COMPLETE "[email protected]". Pls. change the format to "[email protected]" and leave out the single username with the space in front and see if this already solves your issue.

 

[Barungar]

Well, no.. it doesn't... the format looks absolutely fine to me. And it's not a script it's a forum. I've even enabled "debug mode" which allows to write the DATA part of the mail into a file parallel to trying to send it.

To me, that look pretty well formated... and the RPCT TO and MAIL FROM (which is not part of the debug log file) seem also to be okay, that I read in the mail server log, which states (see above) from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<www.example.de>

So the mail send from the forum seems to be fine ...

Hi Barungar,

o.k... fine... then you are sure able to explain, why the mail log only states:

Incorrect recipient mailname : a-bulas

?

 

[Barungar]

No, I'm not... that's why I opened this thread... I don't know why psa-pc-remote doesn't like the mail (format).
I've even connected with telnet to port 25 and simulated an unencrypted smtp transfer with entering EHLO, MAIL FROM, RCPT TO and DATA manually and then pasting the content of the debug log. Well that mail is delivered...

I've rechecked it... that was me some minutes ago; do that same manual smtp... and the mail was delivered and accepted.

Hi Barungar,

actually, you left out the script ( or call it software, because it's part of the Woltlab forum software ) with your test, so this isn't a real proof, that pc-remote should be your root cause.

But you could use a mail client ( account configured for "[email protected]" ) and you could try to send the very same message ( incl. the possible HTML configurations as used for Woltlab ) and send it to a-bulas <[email protected]> . Afterwards you might check your logs and see what the logs say.

If you use quotes in the script, pls. quote not only the username, but consider to tryout as well :

To: a-bulas <[email protected]>
or
To: "a-bulas <[email protected]>"

 

[Barungar]

Well, I thought sending the DATA part via Telnet is quite suiteable to simulate the mail tranfser.

Regarding the source... First I'm no php developer, second I don't know if it is up to me to publish WoltLabs sources and third the forum software has >4.000 php-files ( find . |grep ".php$" |wc -l) ... and I don't know which one is of interesst...

Hi Barungar,

First I'm no php developer

I should inform you, that the Plesk Community doesn't support errors/issues/problems of third-party software/scripts here at the Plesk Community forum, especially not in "Plesk related forums", where you posted your thread ( => Home > Forum > Plesk Discussion > Plesk Onyx for Linux ).
You still have the choice to discuss issues/errors/problems or an general discussion at => Home > Forum > General Discussion > Open Topics for "non-plesk-related" topics.


As a final information to "Woltlab", I can assure you, that SMTP AND PHP-Mail - transport works as expected on CentOS/Debian/Ubuntu - based systems, where wbb3.x - wbb5.x is being used, so pls. consider to check your settings at your Woltlab Admin Panel and consider to ask for support at their forums, if you experience further issues/errors/problems when sending mail over their software/scripts.
