Debian 12 Bookworm mailgraph not creating graphs

[oneilonline]

Debian 12 Bookworm
mailgraph 1.14-20
rrdtool 1.7.2-4+b8

mail.log files being created and contains data.
mailgraph config and permissions set correctly to www-data.
mailgraph service status is "active" no errors reported.
the var/lib/mailgraph dot folder is auto created when the service is started, but that is it only.
Also uninstalled/installed more than a dozen times.
Been troubleshooting and trying different tweaks for the past week.

I've been using mailgraph for over a decade and have always loved it because of it's simplicity.
I've had issues on other distros but have always been able to fix it.
Seams like something at the core changed with this distro.

Anyone else on Debian 12 experiencing the same issues?

Thank you.

I'm guessing you are talking about the new syslog timestamt format.
This is an rsyslog change, not a debian specific change.
rsyslog have a config variable that can bring back the old «MM DD 12:34:56» log timestamp that I have added, which fixed the timestamp format for me.

cat /etc/rsyslog.d/timeformat.conf
$ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat

If you don't want to touch rsyslog format I've made following workaround for this issue.
Disable running of mailgraph as daemon and make manual statistics update via cron script that extract mail log in desired format.
In short it's look like this.

#!/bin/bash
TMAIL_LOG=/tmp/mail.log
journalctl -u postfix@-.service -u dovecot.service -u amavis.service --no-pager --since "1 hour ago" > $TMAIL_LOG
/usr/bin/perl -w /usr/sbin/mailgraph -c -l $TMAIL_LOG --daemon-rrd=/var/lib/mailgraph --ignore-localhost
rm $TMAIL_LOG
