hi-
i'm not quite certain the subject is an accurate synopsis. apologies if it's
misleading. we have a proprietary system which delivers voicemail messages as
email attachments. it submits mail via submission to postfix, which looks like
this:
Sep 18 16:03:33 msa postfix/submission/smtpd[21286]: 3hzTdK1j5ZzyQn:
client=phonesrv.example.com[10.25.40.1], sasl_method=LOGIN,
sasl_username=phonesrv
Sep 18 16:03:33 msa postfix/cleanup[21289]: 3hzTdK1j5ZzyQn:
message-id=<001d7...@phonesrv.example.com>
Sep 18 16:03:33 msa postfix/qmgr[11026]: 3hzTdK1j5ZzyQn:
from=<VOICE/+1nnn5551...@phonesrv.example.com>, size=385664, nrcpt=1 (queue
active)
Sep 18 16:03:33 msa postfix/internal/smtp[21290]: 3hzTdK1j5ZzyQn:
to=<us...@example.com>, relay=mta.example.com[10.3.70.5]:25, delay=0.11,
delays=0.04/0.02/0.01/0.05, dsn=2.0.0, status=sent (250 2.0.0 Ok: queued as
3hzTdK2DdyzJmy2)
Sep 18 16:03:33 msa postfix/qmgr[11026]: 3hzTdK1j5ZzyQn: removed
occasionally, misconfiguration of the system [e.g. a typo, etc.] results in
attempted delivery to an invalid address, which postfix of course rejects. the
client then generates a bounce to <VOICE/+1nnn5551...@phonesrv.example.com>,
which comes back to postfix, since the client relays all mail through postfix.
to ensure this is seen by the right people, i've done this:
main.cf:
recipient_canonical_maps = hash:${table_directory}/canonical_recipients
virtual_alias_maps =
proxy:ldap:${table_directory}/virtual_alias_maps-address_literals.cf
proxy:ldap:${table_directory}/virtual_alias_maps-domains.cf
canonical_recipients:
@phonesrv.example.com
pbx_monitor...@systems.example.com
pbx_monitor...@systems.example.com is a virtual alias:
>postmap -q 'pbx_monitor...@systems.example.com'
>ldap:./virtual_alias_maps-domains.cf
us...@example.com,us...@example.com
this works, but in the received message there is no reference to
pbx_monitor...@systems.example.com - only:
From: postmas...@phonesrv.example.com
To: "VOICE/1nnn5551212"@phonesrv.example.com
how can i add a reference in the message to the recipient_canonical_maps lookup
result [a header, preferably?]? i'd like to do this so the name of the
distribution list/virtual alias can be used in the mua for filtering to a
specific mailbox. i know there are other criteria which would function for the
purposes of filtering, but i'd like to use this method if possible. it would
allow me to avoid reliance on strings/characteristics from the proprietary
system, which may change.
thanks
