I just checked a 10.1 and a 9.3, and those were the same exactly. I
don't understand it. It appears sender_canonical does some but not
enough rewriting the address, but generic worked immediately.
and the man page said this:
DESCRIPTION
The optional generic(5) table specifies an address mapping that
applies
when mail is delivered. This is the opposite of canonical(5)
mapping,
which applies when mail is received.
Typically, one would use the generic(5) table on a system that
does not
have a valid Internet domain name and that uses something like
localdo‐
main.local instead. The generic(5) table is then used by the
smtp(8)
client to transform local mail addresses into valid
Internet mail
addresses when mail has to be sent across the Internet. See the
EXAM‐
PLE section at the end of this document.
The generic(5) mapping affects both message header addresses
(i.e.
addresses that appear inside messages) and message envelope
addresses
(for example, the addresses that are used in SMTP protocol commands).
Which seems exactly what I needed, and indeed did work (but in the
process confused me how it ever worked before). Is the above saying (as
it seems to me) that canonical mapping are only for incoming mail, while
generic is for outgoing mail? Is sender_canonical changing the sender
of incoming mail? That is how it appears, but made me doubt how it
seemed to work before. Thanks again for your help in my trying to get
an understanding of postfix.
