Re: smtp-out: Address family mismatch
Hi,
I don't know what this error entails but I took a peek at the source and
found this in mta.c around lines 1575:
if ((c->source->sa &&
c->source->sa->sa_family !=
mx->host->sa->sa_family) ||
(l->family && l->family != mx->host->sa->sa_family)) {
log_debug("debug: mta-routing: skipping host
%s: AF mism
atch",
mta_host_to_text(mx->host));
family_mismatch = 1;
continue;
}
notice there is a DEBUG level log with a conversion indicating which
host it has problems with. Not saying you need to run it in debug mode,
but you can to see this message.
Best Regards,

Re: smtp-out: Address family mismatch
Currently I have 100+ EMails queued with "Network error on destination MX". This is a severe regression since OpenBSD 6.6. Every insightful comment is highly appreciated Please show your complete config file. Maybe it has an error. My current (new-style) smtpd.conf has a line action "relay_external" relay src 192.168.1.1 helo "mail.example.com" Does your original config has a private IP-address too? Maybe you are behind a janky NAT router?
Re: smtp-out: Address family mismatch
Hi, I had these when I changed my secrets password, smtpd needs to be restarted after.

Hi Thomas,

My guess would be that the target domain, at the time of the DNS query, only

I have a similar problem. My config is
action "relay2Internet" relay \
helo $hostn \
src {$v4adr, $v6adr}
as I want to allow IPv4 and IPv6. Since the src-adresses are getting alternated I often
get "Address family mismatch" because the target doesn't have IPv6 yet. (At
least I believe that is what's happening.)
Sorry to say, but thats pretty unlikely. IPv4 is much more common than
IPv6 (still), especially for EMail.
I would guess thats a bug. Somebody didn't care about the old-style
limit mta inet4
for the new config file syntax.
