To read and write I'm using mutt as MUA. mutt can fetch with IMAP(S) and
send with SMTP+SSL; but this (sending directly) is not what I want, I
want to queue up the outbound mails and send them at once (see above for
the reason); so, sendmail is the natural option; 

for the PPP link, I already use a devd(8) hook to restart sendmail when
the interface comes up; for the wlan(4) link I will use the hook
/etc/dhclient-exit-hooks looking for the $reason BOUND;

I was hoping for a solution which combines all interfaces in one place,
but it seems that this does not exist.

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.-
