set_from_header not working

[msafadieh]

I've been trying to setup msmtp to automatically rewrite the from headers for my cron emails. I put set_from_header on in my config file per the documentation but it seems like sendmail is ignoring that.

This the log output. As you can see the from header is different than the one in the config file.

Sep 26 09:51:02 host=smtp.purelymail.com tls=on auth=on user=log@mhmd.sh from=mhmd recipients=[REDACTED] smtpstatus=530 smtpmsg='530 5.7.1 You (log@mhmd.sh) are not authorized to send mail as mhmd@purelymail.com' errormsg='envelope from address mhmd not accepted by the server' exitcode=EX_DATAERR

This is my config:

account status
host    smtp.purelymail.com
port    587
from    log@mhmd.sh
user    log@mhmd.sh
password password
tls on
auth on
set_from_header on
logfile ~/.cache/msmtp.log
tls_trust_file /etc/ssl/certs/ca-certificates.crt

aliases /etc/aliases
account default : status

I cannot reproduce this error, it works for me.
Can you provide a --debug output for a small example mail?
(Be sure to remove authentication lines).

Something like
echo -e "From: wrong@address\nSubject: Test Header\n\nTest Body" | msmtp --debug recipient@example.com

That seems to work fine. I was able to fix the issue by telling cron to use msmtp -t instead of sendmail as instructed on the ArchWiki.
