Ah, I see – I didn't know that. Thanks.

But, then again there is an explicit virtual interface with that IP on
my server Host A:

ens3: IPv4 & IPv6
ens3:400: IPv4
ens3:401: IPv4
ens3:402: 1.2.3.4 (IPv4 only)
ens3:403: IPv4

(and so son)

I would have that thought that exim then chooses ens3:402 for outgoing
mail, but it decides to use ens3 and IPv6. Is there any way to change
this behaviour?

I have another server which has IPv4 only and several virtual Interfaces
in the same configuration and Exim chooses the right virtual interface
(the one configured in the transport) for sending mail on this machine.
