Hello,

I'm trying to configure outgoing email using Amazon SES SMTP on Postgresus, but SES rejects the message with this error:

501 Invalid MAIL FROM address provided

The SMTP form in Postgresus does not include any field for “From Email” or “Sender address”. SES requires the MAIL FROM domain to match a verified identity. Since the app doesn’t expose that setting, it seems to use a default internal sender (like root@localhost), which SES rejects.

Could you please clarify:

How to explicitly set the MAIL FROM / From address in Postgresus?
If it’s currently not supported, could you add an option for specifying a verified From address?

Thanks.

Could you please clarify: 1. How to explicitly set the MAIL FROM / From address in Postgresus? 2. If it’s currently not supported, could you add an option for specifying a verified From address?
