It happens to me as well on any aliases I have on workspace. It will use
the primary address of the account for the RFC5321.mailfrom rather than
the responding alias. Vexing, but it's covered by DKIM, so... meh.

Hey all,
After configuring email alias domains on Google Workspace/G Suite, and
then when sending from an alias domain, I note that while DKIM
authentication works and is aligned to the from domain, that SPF
authentication does not align; Google always uses the primary domain
in the return-path, leading to a lack of SPF alignment.
Example:
Primary domain: wombatmail.com
Alias domain: spamresource.com
If I use my...@wombatmail.com account to send as...@spamresource.com:
SPF/return path:b...@wombatmail.com
DKIM: spamresource.com
Thus I get no SPF alignment.
As far as I can tell, this is a limitation of Google Workspace, but I
figured I'd ask around to make sure I'm not missing something.
Feedback welcome, thanks in advance.
Cheers,
Al Iverson
