Package: exim4
Version: 4.92-8+deb10u3
Severity: normal
Tags: ipv6
Dear Maintainer,
I was getting a "Relay not permitted" message from Thunderbird trying to send
e-mail.
The immediate workaround was to change the "Server Name:" in Server Settings
from "localhost" to "127.0.0.1". However, the manpage says, and said in squeeze
[1],
> dc_relay_nets
> A list of machines for which we serve as smarthost. _Please note that
> 127.0.0.1 and ::1 are always permitted to relay since /usr/lib/sendmail is
> available anyway and relay control doesn't make sense here._ Sets macro
> MAIN_RELAY_NETS
(I actually had "...; 127.0.0.1/8; [::1]/128; ..." in dc_relay_nets, but
taking those entries out didn't seem to make any difference.)
Testing with "telnet", IPv4 localhost is allowed to relay, IPv6 localhost isn't:
# telnet -4 localhost 25
Trying 127.0.0.1...
Connected to localhost.
