hi-
i have an "appliance" which submits mail. it's inflexible,
unfortunately, and uses crappy values for the envelope sender and the
from: header. i have communicated with the vendor in an attempt to
rectify this, but as might be expected, the outcome has been less than
successful.
hopefully some day, this changes, but in the interim, i'd like to
rewrite the envelope sender and the from: header [ala
sender_canonical_maps] for all mail from this client.
how should i do this? is the best method to set up an additional
cleanup(8) instance with its own sender_canonical_maps for just this
client? somehow connect the client to its own smtp(8) service to use
smtp_generic_maps? are there other/better methods?
thanks

depending on "how" the addresses are broken, you can probably just
use canonical_maps to always rewrite the offending address to
something valid. There shouldn't be any need for additional cleanup
service unless you're fighting some common misspelling.
Send specifics of what you're trying to rewrite for further help.
in particular, this client impersonates our users, which we don't want. it is aware of
users and their email addresses [it's part of a voicemail system which sends voicemail
messages as email attachments, and "helpfully" claims the email message was
sent by the caller]. for us, this is undesirable.
when a user submits a message with a sender of u...@example.com, we of course
don't want to change that. however, when this client does it, we do. the
localpart is dynamic. for example, i would like to rewrite a sender of
/^.*@example.com$/, but only when the message came from this client. many
other messages with a sender which matches /^.*@example.com$/ are submitted
from many other clients, but those don't need to be changed.
You might be able to create an extra service on a different port or ip
address for this appliance that has sender_canonical_maps defined?
