Description	After updating from postfix.x86_64 2:3.3.1-12.el to postfix.x86_64 2:3.5.8-1.el8 I'm getting frequent log entries Mar 19 10:51:58 mail postfix/smtpd[XXXXXX]: discarding EHLO keywords: CHUNKING After further research it appears this was compiled into the package: # postconf -d \| grep smtpd_discard_ehlo_keywords postscreen_discard_ehlo_keywords = $smtpd_discard_ehlo_keywords smtpd_discard_ehlo_keywords = chunking Could you let me know why CHUNKING / BDAT has been discarded?
