The VuXML for OpenSMTP (https://www.freshports.org/vuxml.php?vid=40c75597-574a-11ea-bff8-c85b76ce9b5a) says `lt 6.6.5,1`, but the fix for this issue is in 6.6.4p1. Eyeballing the patch at https://ftp.openbsd.org/pub/OpenBSD/patches/6.6/common/021_smtpd_envelope.patch.sig matches the code in the port as of last night. I believe the VuXML should be changed to say `lt 6.6.4,1`.
This may have been fixed by ports r527243 Assign to committer to verify
Yes, it should be fine after r527243 Pointyhat to cs@ for committing wrong versions even without contacting with me for maintainer approval PR will be closed after FreshPorts information will be refreshed
