all gmail bad signature data

i'd really appreciate a resolution for this - seems like sendmail is the
culprit since it can't seem to extract email addresses to send reports to

every email i receive from gmail gets bad signature data
every email i send to gmail passes all SPF/DKIM/DMARC

aside from gmail, i don't ever recall seeing any problems for any
outgoing email for dkim/dmarc/spf

also, i have seen plenty of logs for valid dkim sigs, adsp, and
dmarc=pass, etc

ive setup most reporting options for dkim/dmarc as:

MTACommand /usr/sbin/sendmail -C /etc/postfix/ -vv -t -f

ReportCommand /usr/sbin/sendmail -C /etc/postfix/ -vv -t -f

running opendkim/dmarc on debian jessie amd-64

$ opendmarc -V
