Comment on Recommendation for outgoing-only SMTP server

You can definitely replace senders with correct mail addresses for relaying through SMTP server that expect them (this is what I do):

# /etc/msmtprc
account default
...
# Replace local recipients with addresses in the aliases file
aliases /etc/aliases

# /etc/aliases
mailer-daemon: postmaster
postmaster: root
nobody: root
hostmaster: root
usenet: root
news: root
webmaster: root
www: root
ftp: root
abuse: root
noc: root
security: root
root: default
www-data: root
default: myaddress@gmail.com

In the issue I linked, the msmtp author makes a distinction with changing the envelope recipient, which msmtp can do, with rewriting the email headers like “To”, which msmtp does not do.

  github.com/chriswayg/ansible-msmtp-mailer/…/14 While msmtp has features to alter the envelope sender and recipient, it doesn’t alter the “To:” or “From:” message itself. When the Envelope doesn’t match these details, it can be considered spam
  
  Oh I didn’t know that, good to know!
  
  The proposed one-line wrapper looks like a nice solution
