unionmap (read-only)
A table that sends each query to multiple lookup tables and that
concatenates all found results, separated by comma. The table name
syntax is the same as for pipemap tables.
(http://www.postfix.org/DATABASE_README.html#types)
Seems a little unclear to me how it works :-( Maybe by example. Let's
assume:
virtual_alias_maps = unionmap:{sth1, sth2}
What is the result of `rcpt to:' set to `someone1' in the original mail?
if:
`sth1' maps someone1 -> someone2,someone3
`sth2' maps someone3 -> someone4
if:
`sth1' maps someone1 -> someone2,someone3
and someone4 -> someone5
`sth2' maps someone1 -> someone4
if:
`sth1' maps someone1 -> someone2
`sth2' maps someone2 -> someone1
if:
`sth1' maps someone1 -> someone2
and someone3 -> someone4
`sth2' maps someone1 -> someone3
and someone2 -> someone5
