According to RFC 5321 section 5.1, the sending host should try at
least two delivery addresses.
Quote:
When the lookup succeeds, the mapping can result in a list of
alternative delivery addresses rather than a single address,
because of multiple MX records, multihoming, or both. To provide
reliable mail transmission, the SMTP client MUST be able to try
(and retry) each of the relevant addresses in this list in order,
until a delivery attempt succeeds. However, there MAY also be
a configurable limit on the number of alternate addresses that
can be tried. In any case, the SMTP client SHOULD try at least
two addresses.
If you believe that Postfix should wait between the attempts to
connect to the first and the second MX address, then you are in
error.
