[Rspamd-Users] Trouble with sockets to ClamAV and Spamd

[usenet at schani.com]

Hello,
I just have the problem that my Rspamd 3.7.4 on debian 12 does not 
create socket connections.
I use ClamAV and at local.d/antivirus.conf:

ClamAV {
     symbol = "CLAM_VIRUS";
     type = "clamav";
     action = "rewrite subject";
     servers = "/var/run/clamav/clamd.ctl";
     max_size = 200000000;
     scan_mime_parts = false;
     log_clean = true;
     timeout = 10;
     retransmits = 2;
}


The error message I get in rspamd.log is:
2023-11-15 18:22:10 #7289(rspamd_proxy) <dc0ec5>; lua; clamav.lua:117: 
ClamAV: failed to scan, maximum retransmits exceed

The file sizes in clamav.conf are 25MB and to test I send a 2MB PDF.

Even in Spamd, i.e. Spamassassin, I get the error message:
SPAMD_FAIL (0) [failed to scan and retransmits exceed: Socket error 
detected: connection establishment refused]

Is there something fundamentally wrong with my setup?
What could be the reason?
Thank you very much for help
Christian
