[exim] Exim with IPv6

Hi, list!

Since I have now an IPv6 subnet, I'd like to have my Exim (4.75 from source)
running on the IPv6 interface, too...

I read the documentation, and I found, that I have to set:

    local_interfaces = <; ::0 ; 0.0.0.0

to listen to all IPs (IPv4 and IPv6), but if I do that, I get this error:

socket bind() to port 25 for address (any IPv6) failed: Invalid argument:
waiting 30s before trying again (9 more tries)

Do I have to give some special options by compiling, to have Exim using IPv6?

Thanks a lot!
