PHP 8.X compatibility

[piperino721]

Hello

Are there any plans to make your mailzu fork compatible with PHP 8+.
Got it partially working copying some files over from a Freebsd Repo. https://www.freshports.org/security/mailzu/
Unfortunately, i have no coding skills but could help testing.

How far have you come? What are the remaining errors? That could give some indication of how much work there is to do.

How far have you come? What are the remaining errors? That could give some indication of how much work there is to do.

I use it on openSuse Leap 15.5 with PHP 8.1.24

-Since i just using LDAP i can say LDAP Login is working.
-Site Quarantine overview as admin is working
-User Quarantine overview is working.
-Open a quarantined mail is NOT working. all mail field are empty.

-Release quarantined mail is NOT working. it tells me can't connect. even though port is listening. amavisd-release is working just fine.

tnx

It would be good what errors you are getting from your webserver logs. That should indicate where there is work to do.

No errors in logs while trying to release a mail from quarantine

### Whatever errors:)

hope this helps a bit

It seems mycomment got vanished.
First in composer.json there is a php 7.2 as far i know.
To fix most PHP upmigration issues, i would use RectorPHP

[apio-sys]

@piperino721 even though the warnings don't look nice, I don't think they are actual showstoppers or you would have seen Fatal Errors in your log. After a previous U/G from Debian 10 to 11 and thus PHP 7.2 to 7.4 I had a similar error (at least I think it is similar to yours) where mailzu hangs on "retrieving messages". I found out that the mbstring extension was missing in PHP. Hence a simple:

apt-get install php-mbstring

solved that. Maybe that is your case as well? Maybe go through all PHP config and chech against a working installation (my highest install is on 7.4).

php81-mbstring is installed here.

OK that was just a hunch. There must be something else blocking. The warnings in your log don't explain this. Try and put your PHP to debug level, for example via your php.ini to so if you can capture some more info.

[piperino721]

this is what i get with "display_errors = On" in php.ini

**Just saw when i try to release a message it is trying to connect to the FQDN of the server on port 9998 which is of course not allowed.
even though in the config is:
// Set Amavisd-new host, if AM.PDP only allowed over localhost
$conf['amavisd']['host'] = 'localhost';

also tried 127.0.0.1 but it makes no difference.**

[apio-sys]

Your log shows only warnings so the issue doesn't come from there. It might well be a system/configuration issue. Indeed amavisd runs on 127.0.0.1:9998 and that's where it should be adressed. You should have this in your config/config.php:

// Amavisd-new AM.PDP port
// Since the port number can not be stored in the database
// all instances of amavisd-new must use the same AM.PDP port 
$conf['amavisd']['spam_release_port'] = '9998';

// Set Amavisd-new host, if AM.PDP only allowed over localhost
$conf['amavisd']['host'] = '127.0.0.1';

which can't point to the FQDN...

[piperino721]

The logs are written while trying to open a quarantined mail. thats one issue.
the other is releasing mails.
My config for the AM.PDP looks exactly like yours's.
Whatever i put in "$conf['amavisd']['host']" i always get "Error connecting to hostname.mydomain:9998, Connection refused"
But maybe this is just a generic error from the GUI and there is another Underlying firing the amavisd-release command

no idea why PHP/mailzu is doing this

Besides that the system runs fine for years.

[apio-sys]

Difficult to say but IMHO it still doesn't look like a pure PHP issue. When I release a quaraintained mail, I see following in the webserver logs:

[27/Feb/2024:16:19:56 +0100] "POST /mail-quarantaine/messagesProcessing.php HTTP/2.0" 200 2309 "https://example.com/mail-quarantaine/read_mail.php?mail_id=XPS6_vHb0Yed&recip_email=ping%40example.com&ctype=A&searchOnly=0" "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:123.0) Gecko/20100101 Firefox/123.0"

Maybe you can better see what happens here when the error in the GUI occurs?

[piperino721]

below is all i get. i think it's something in the code or with some PHP libraries needed for mailzu is wrong or missing.
also on the same machine nextcloud and roundcube is running fine.
the error from the is already posted.

BTW. you run it on php8 or php7?

[apio-sys]

I'm still running this on 2 machines both on PHP 7.4. I can't U/G PHP as yet since I have other software that I know is not compatible. Maybe MailZu isn't neither but we haven't really proved that unfortunately... To be able to further help, I would need to change the PHP version of one of my machines but can't do immediately since these are prod... I'm not sure if I can help further. Did you notice the change directly upon upgrading that machine or upon moving the webapp to a different server? The call of FQDN rather than localhost still sounds fishy and I'm almost convinced it's not PHP and some sysconf somewhere...

[piperino721]

No worries. i just thought i can't loose anything asking here:).
i think mailzu stopped working when i upgraded to php8+ .
