Basically you should never modify messages. > How can I make this work? Is there a good way to use something like > /etc/aliases to forward emails to the domain I manage to another > recipient? Or is there something better I can do? I think the advice to set up IMAP and submission is wise. I realize this may be a small non-profit, but company mail belongs on company servers, and personal mail on personal servers. With IMAP and submission, your president can have their outgoing email be presid...@myassociation.org, DKIM signed, with an SPF record, and even DMARC. If someone writes and gets a reply from a random gmail account, that is at best confusing.
