> Ok, just in case this helps someone else: I've fixed the long waiting
time, which was answered in another thread: "[exim] changing time for 25
to answer". I just added rfc1413_query_timeout = 0s to my config and now
it negotiates quite fast.
I still haven't resolved inside-outside port 25 problems. Why can't I
telnet from the outside but I *can* smtp from the outside? I've
double-checked there are no firewall rules, smtp connections are not
using ssl or tls... Can there be some sort of ISP filtering?
