# postconf | grep chunking smtpd_discard_ehlo_keywords = chunking # journalctl -u postfix | grep CHUNKING May 23 03:40:59 mail01.raystedman.org postfix/smtpd[401681]: discarding EHLO keywords: CHUNKING <<We saw 24 of these log entries in 24 hours.>> We are running the latest version of RHEL 8. I believe a number of us will be seeing this entry in our logs. What are the negative side effects beyond the log entries? Is "smtpd_discard_ehlo_keywords = chunking, silent-discard" the recommended solution? Thanks, Greg www.RayStedman.org
