External forwarding in 2024 is rather fragile anyway, isn't it?

I'd consider this a task for the MTA doing the deliveries of the
messages submitted by Dovecot to ensure that all external messages have
an envelope sender which would make SPF happy (even though I see that
Cyrus' Sieve gained SRS support in 2010). SRS requires coordination with
the MTA listed as MX for the domain used in the SRS envelope anyway, so
one might as well just do all rewriting on the MTA level.
