Milter "can't read SMFIC_OPTNEG"
Posted: 03 Mar 2021 19:14
Hello,
I run a high traffic server and lately I've been seeing these errors in the Maillog just after the servers stops processing incoming emails:
Netstat shows:
After I reboot the eFa-project servers, the emails resume processing and the incoming queue starts to go down in count.
I've looked everywhere and cannot find the cause for this.
Does anyone here have any experience with the "can't read SMFIC_OPTNEG" error?
