Postfix-Server (simple postscreening and relay) -> Antivirus/Antispam-Server (CLAM and SA managed with AMAVIS) -> Kopano-Server.
This is a real 3-Server (Hardware/VM) scenario.
- Postfix works and send the mails correct to the AMAVIS-Server -> working
- AMAVIS moves the mails to CLAMAV -> working
- AMAVIS moves the mails to SA -> working
- Now AMAVIS is configured to send the mails to Kopano via IP:LMTP to DAGENT
AMAVIS get now an error:
