In the exim advanced configuration manager, Amazon SES is used as the global domain to send and forward emails. SRS rewriting the sender has been enabled, but when the automatic forwarding of emails fails and needs to be returned to the original sender, an error 501 Invalid MAIL FROM address provided is reported.
return_path = ${srs_encode {SRS_SECRET} {$return_path} {$original_domain}} So how should this configuration be optimized and modified?
