I blame Thunderbird. List is preferred, as far as I'm concerned.

Oh, now _that_ is fun. Exim is merely reporting what the
OS tells it. If you strace that telnet, is it actually
the "connect" syscall that returns EPERM? That's the implication
of the error message.

The Linux connect(2) mapage offers EPERM for a local firewall
rule, but yours is remote... I wonder what a packet capture
shows?
