>Description:
I build postfix by enabling eai option:
$ bmake show-options
Any of the following general options may be selected:
        eai      Enable EAI (Email Address Internationalization) support.
        sasl     Enable SASL support.
        tls      Enable TLS support.

These options are enabled by default:
        tls

These options are currently enabled:
        eai tls

You can select which build options to use by setting PKG_DEFAULT_OPTIONS
or PKG_OPTIONS.postfix.

But I get the following message in logs:
2019-07-02T09:26:20.904352+00:00 mail.triaxx.org postfix/master 2206 - - daemon started -- version 3.3.3, configuration /usr/pkg/etc/postfix
2019-07-02T09:26:20.938819+00:00 mail.triaxx.org postfix/qmgr 27447 - - warning: smtputf8_enable is true, but EAI support is not compiled in
>How-To-Repeat:
export PKG_OPTIONS.postfix=eai && cd mail/postfix && bmake install
>Fix:
