Sendmail will produce these headers.

The problem isn't the sender or gnus really, it's how sendmail is
invoked, with command line arguments to set the SMTP MAIL FROM, or
approximately that, my brain is fading.

I solved it on my end by adding myself as a trusted user to my
sendmail.cf, check out this section if you have it in your sendmail.cf:

#####################
#   Trusted users   #
#####################

# this is equivalent to setting class "t"
#Ft/etc/sendmail.ct
Troot
Tdaemon
Tuucp
