Hi!

Can you elaborate on this?

chasquid already supports forwarding with SRS. If you alias to a non-local domain, then SMTP forwarding with SRS will be used.

Thanks for the details. The documentation does not explicitly indicate which mechanism is used for this.

I see! I can fix that, thanks for pointing it out.

I'll leave this open to track the documentation improvement.

docs: Document the use of SRS when doing alias forwarding
65afb02 
When an alias has a remote destination, chasquid uses sender rewriting
(also known as SRS [1]) to forward the email without risking being in
violation of SPF policies.

See https://en.wikipedia.org/wiki/Sender_Rewriting_Scheme for more
details.

This, however, wasn't documented anywhere, as noted in
#6.

This patch adds a paragraph to the alias documentation explaining this
behaviour.

Commit 65afb02 adds a paragraph about this in the aliases documentation.

Thanks for the report, and please let me know if you have any suggestion or comment to improve it!
