not fatal, but wasted effort, and noise in the logs.
how/where do I configure (just) the dovecot smtp-client -> submission_relay_host to only connect IPv4?</pre>

<p>It appears your host has A and AAAA records in your DNS. The
clients will try IPV6 first if they see an AAAA record.<br>
</p>
<p>If you don't need IPV6 for your host remove the AAAA record. All
connections will then only use IPV4.</p>
<p>If you need IPV6 for some other reason then create an alias DNS A
record and point your clients to that instead</p>
<p>e.g.</p>
<pre>myhost A 192.0.2.1</pre>
<pre> AAAA 2001:db8::1
myhostv4 A 192.0.2.1
</pre>
you will have to change your certificate to include the alias
myhost4<br>
