Is having multiple instances also the only solution if I'm in process
of changing my official IP address (as we are changing provider)?

I would like to set
        inet_interfaces = <newIP> <oldIP>
so it listens to both (does work) and would send out on any (the first)
of them (does not work as both IPs are only aliases and smtp_connect
does not bind).

I also tried the other suggestion using
        <oldIP>:smtp ... smtpd
        <newIP>:smtp ... smtpd
in master.cf (no inet_interfaces in main.cf), which works for listening.
But then the smtp-sender does not know about my interfaces (at least I
couldn't tell him).
