Re: smtp-out: Address family mismatch

Hi Thomas,

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.

Did you ever figure this out? I'm having the same issue. I have a linux system 
with Logwatch set to e-mail 'root', and the root user has a ~/.forward to a 
fully qualified e-mail address (u...@example.com). It only started happening on 
June 11, when I upgraded opensmtpd from 6.6.4,1 -> 6.7.1,1 (on my mailserver, 
which is FreeBSD). I get the same "ORCPT address syntax error" you're seeing. 
Here's the log from smtp when it happened yesterday:

Jul 10 03:19:03 roast smtpd[80856]: 66aa64942b25c1fd smtp failed-command 
command="RCPT TO: ORCPT=rfc822;root" result="553 ORCPT 
address syntax error"

The linux system hasn't been changed in years, and it started happening 
immediately after the upgrade of opensmtpd, so I imagine it's related to that.
