Despite the fact that I do not need to understand why you want to have
the proxy on the same host (probably debugging/development purpose?),
your config looks quite plausible. But never I used nginx as a proxy. I
used haproxy.

There is no sense in defining a host list w/o using it.
Defining a hostlist as above just creates a list of host items, named
"hosts_proxy".
This doesn't imply any use of the list.
However, there is a main config option "hosts_proxy", which accepts a
host list - that is, a list of host items, or a list that was defined as
a host list previously:
Given your config from above
# referring to the hostlist "hosts_proxy" defined above
hosts_proxy = +hosts_proxy
or
hosts_proxy = <; 127.0.0.1; 192.168.111.11
should work.

Re: [exim] How to make proxy support work in exim
Proxy protocol is an optional feature: if this: exim -bV | grep '\WPROXY\W' prints nothing you will need to install a more feature-rich build of exim. > ``` > hostlist hosts_proxy = <; 127.0.0.1; 192.46.111.11 > ``` > But PROXY protocol seems to be not recognised by exim loose the "hostlist" hosts_proxy = <; 127.0.0.1; 192.46.111.11 or use the host list explicitly hostlist hosts_proxy = <; 127.0.0.1; 192.46.111.11 hosts_proxy = +hosts_proxy https://www.exim.org/exim-html-current/doc/html/spec_html/ch-proxies.html -- Jasen. -- ## List details at https://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/

Looking at the nginx docs pages I suspect that nginx is only being an smtp forwarding MTA, talking SMTP to the eventual destination and not proxy-protocol. If so, you must not configure your exim to expect proxy-protocol, and you'll have to remove from your config anything that depends on the source IP (and rDNS name corresponding), since that will always be the nginx system. -- Cheers, Jeremy -- ## List details at https://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
[exim] How to make proxy support work in exim
Hi
Nginx and Exim on the same host, Nginx runs as a smtp proxy for exim.
Nginx v1.22.0 config fragment:
```
mail {
...
server {
listen25;
protocol smtp;
proxy_protocol on;
smtp_auth none;
starttls on;
}
...
}
```
(Exim v4.96, compiled with SUPPORT_PROXY). Exim config:
```
hostlist hosts_proxy = <; 127.0.0.1; 192.46.111.11
```
But PROXY protocol seems to be not recognised by exim, Exim logs:
```
SMTP syntax error in "PROXY TCP4 209.85.128.171 192.46.111.11 43960 25"
H=localhost [127.0.0.1] unrecognized command
```
How to make proxy support work in exim?
Thank you
