As mentioned by Peter, based on the docs and the weight= option, it should
be randomized but not sure if a weight has to be explicitly declared for
randomization to kick in.
Alternatively, spamd_address is expanded so you could stick the servers IPs
in a file and make use of ${randint:n} with a lookup. ${lookup
{${randint:3}} lsearch{/path/to/file}}
where the file contains:
0: 10.10.10.10 783
1: 11.11.11.11 783
etc.
