Random delivery

[Jorge Bastos]

Hi Joseph,

It's that what I want!!
Sequentially, my bad saying random!

Well... with the script, I remember I did something like this 15 years ago
with qmail with a php script, that every email was saved in mysql and I
always selected the next email addrr in the list.

Going to search for this option in postfix, thanks for the tip as this is a
bit offtopic of dovecot,

It's almost always possible; it really depends on how much work you want to
do.

Others have suggested a postfix method.  You can also pipe it to a script
that will select a destination to forward to alias "info at domain.tld" to
"|/my/selector|script".  This will work both in Postfix, sendmail, and
probably most other MTAs.

If you actually want randomization (rather than sequential round-robin), you
can simplify because you won't need to record the last delivery.  Use
/dev/urandom or unix time() mod 3 to select forwarding address.
