The inbound direction is:
ISP--(imaps)--fetchmail--(smtp)-->sendmail(localhost:25) --> procmail-->mbox...mutt
The outbound is:
mutt--(sendmail)--> queue
and after link-up and 'sendmail -q' all mails are send out
queue--(sendmail)--(smtp/TLS)--> ISP MX
I think, this scenario is pretty much fine and LISTEN is only on
localhost:25; it requires only DNS working correctly in the moment of
receivin and sending;
This is what I asked for: how to ensure that DNS+sendmail is fine after link-up
on any interface (wlan0, tun6, ...)

La referencia de la Duma a la anexión de la RDA, en este caso al contrario con la Crimlía sin
referéndum, no solamente tiene gracia sino da en el blanco.-
