There is a fix for that ftp://ftp.sendmail.org/pub/sendmail/snapshots/sendmail.8.18.0.2.tar.gz Accept only CR LF . CR LF as end of an SMTP message as required by the RFCs when the new srv_features option 'o' is used. Although, the configuration must be altered to enable it.
Thanks for the info, waiting for the stable release.
Fixing only in the rawhide (f40) by rebase to currently stable sendmail-8.18.1.
