Is it possible to only forward outgoing mail?

[madhavgharmalkar]

Hello,

I was wondering it is possible to forward only outgoing mail with the queue/smtp_forward plugin? I'd like to receive mail and forward it to my IMAP server via LMTP (queue/lmtp) and forward my outgoing mail to SES / Sendgrid etc.

Is this possible?

Yes, it is possible. It's also possible to be even more specific. Plugins can set queue.wants to whichever queue plugin they wish to deliver a message and queue.next_hop to further direct that queue plugin.
