I built email servers for a non-profit I volunteer for. If email

normally just create an alias in /etc/aliases so that emails to
president@ get forwarded to the president's "real" email address, say
presidents_real_em...@gmail.com.
postfix supports expand_owner_alias, which, when you are sending to
al...@example.com, will set sender to owner-al...@example.com.
That way SPF should pass.
The problem is, when I send email to presid...@myassociation.org,
gmail rejects the forwarded email because it appears to come from my
personal domain, not the mythical myassociation.org domain. DKIM,
DMARC, and SPF all fail, which I totally understand.
How can I make this work?
DKIM should not fail, unless you modify the message. Do you modify the
message?

If your dkim signature is OK, then Gmail does accept all
mails. So never use SRS. DKIM is enough.
This is not a good advice. Whoever filters SPF at SMTP time will reject
that message. Gmail is not the only mail service available.
Initially, I was seeing errors where GMail didn't list SPF as "passed."
But after about an hour, it started passing. I think it was an old DNS
record that finally expired.
The forwarded email is being *accepted* by GMail. My issue now is that
GMail drops it into the recipient's spam folder. I suspect it's a
reputation thing. Once the server is up and running for a while, I'm
hoping that GMail will stop flagging the emails from the server as spam.
