I have my hostname in rc.conf defined as a FQDN - ending in a dot. IIRC
it's needed to prevent sendmail waiting a long time for DNS if the

I recently noticed that when I send myself email through sendmail I'm
hitting this spamassassin test at my email service:
2.3 FH_HELO_ENDS_DOT Helo ends with a dot
It doesn't actually matter to me, because I don't use sendmail much,
but what are the rights and wrongs of this? I was under the impression
that any name used in an helo/ehlo should be a FQDN.
AFAIK, an FQDN does not need to end with a dot. While they do, by definition, end with a dot, that nomenclature is typically only used in DNS zone files.
FWIW, I've never noticed a problem with slow boot when there's network problems. If you do notice problems, simply make an entry in the /etc/hosts file to map the local hostname to it's corresponding IP address.
HTH.
