Remove log.[ch] now that we have stderr logging

Add support for the z mail header. -z adds the mail headers used in the signature -Z adds all the mail headers

Add -x flag

Add support for the t header

Move signing component to own function for clearer reading

Delay smtp_filter_disconnect until commit phase to prevent unintentional shutdown

Fix accidental whitespace

Remove custom custom mkstemp/fdopen dance with tmpfile. Requires fattr, but can hopefully be removed in the future

Revert previous. Seems to be an issue with smtpd, not fully confirmed upstream

Remove trailing \r characters. These come in before filtering, but don't survive upon delivery

Fix line-counting by skipping over \r on the end of the line. Also fix wrong signature length check while here

Don't do event_pending check before trying to write. If we can flush multiple mails at once this can result in major contingency on the output buffer before we hit the output check

Canonicalize line before applying test rules to it This makes 100% from 12200 mails succeed

No need to add the \r the origf buffer

If we're doing a FWS just after a header name separator, also remove the leading space from the value

Don't do fieldname parsing on a continuation line

Correct for dot escape on smtp-layer

Only parse ':' if we're still parsing the fieldname

A pointer change should be accounted for

Fix horrendous miscalculation

Remove accidental commited debug printfs

More OBO
