Sorry for my dimness (not doing this daily) but do I understand this correctly
as:
- Message is deliverd to normal transport (smtp process A) first
- transport_maps in main.cf says: “when recipient is example.com
<http://example.com/>, use transport mycanon)
- Message is delived to mycanon transport (smtp process B) from normal
transport (smtp process A)
- mycanon transport replaces myorigin with the alias
Correct?
