Hello,

See attached for example content of /proc/self/status and the dovecot.conf through 'dovecot -n'

I am re-sending this message because there were a lot of DMARC reports due to my reject policy and the Dovecot list settings.

Hello,
Writing to get some insight as to how I might rid myself of a the pesky error message on the subject. Every binary throws out that error, every LMTP delivery... basically every time any dovecot binary is executed. I am unsure if this is configuration related or not, but intuition says it is an issue with a kernel feature or compiler issue.
I saw the error message in the source code (file ), but I don't understand enough of the dovecot architecture or what the code itself is doing in this case. Below and excerpt of a few lines of logs. Since I don't know what specifically this would relate to (and I don't quite remember the command to send the "safe" version of the configuration), I am sending this message in hopes that whatever is needed can be asked and I will provide it.
