Dear Proxmox Staff,
Net::DNS::RR::NS 1814 at /usr/share/perl5/Mail/SpamAssassin/Plugin/ line 583, <GEN7998> line 2678.
I have a proxmox error in log. Unfortunately, this causes some emails to be lost.I couldn't find a rule among the senders, sometimes it works, sometimes it doesn't.
The Spamassassin is default.

Please use [code] tags for logs and traces - else it's not easily readable...

* do you have any custom spamassassin configuration/plugins/adapations?
* please provide `pmgversion -v`
* how is your DNS setup? (what's the resolver used by PMG - how does your /etc/resolv.conf look)?[/code]

Hy Stoiko,

Do you maybe have spamhaus-dqs installed on that system? - there are a few threads in this forum with similar descriptions - and all affected users used spamhaus-dqs
There is nothing completely basic, I don't even understand it that much.
The whole proxmox base is set only on filtering.

hmm - that's odd - does DNS resolution work in general on the PMG?

please also provide:
* `spamassassin -Dall --lint > sa-lint.out 2>&1` (it will generate a file sa-lint.out)
maybe then we can see where the issue is
Ok - on a first glance nothing stands out (sadly).

does DNS-resolution work in general on the box?:
* `apt install bind9-dnsutils` (to get the `dig` command)
* `dig ns`
* `dig mx`
* `dig`

post the results as [code]
hy Stoiko
Of course, everything works, there is only this log entry.

Sadly I'm unable to reproduce the issue here - and I did not find too many fitting hits - as said above

Just in case - you did try rebooting the PMG?
(while this still would be odd if it fixes things)
could you share the complete contents of /etc/mail/spamassassin
not a listing of the files - but the complete files - put them in a tarball/zip please
I'm not a big linux wizard :(. Winscp worked.
