The snapshot dir of Postfix was removed, there's now just stable35
(the last version that can be built with libressl) and stable.

There are probably valid use cases for both. Note, you can do this:

$ pkg_info -I postfix%stable
postfix-3.8.6v0     fast, secure sendmail replacement
$ PKG_DBDIR=/var/empty pkg_info -I postfix%stable
postfix-3.8.6v0     fast, secure sendmail replacement
postfix-3.8.6v0-ldap fast, secure sendmail replacement
postfix-3.8.6v0-mysql fast, secure sendmail replacement
postfix-3.8.6v0-pgsql fast, secure sendmail replacement
postfix-3.8.6v0-sasl2 fast, secure sendmail replacement
postfix-3.8.6v0-sasl2-ldap fast, secure sendmail replacement
postfix-3.8.6v0-sasl2-mysql fast, secure sendmail replacement
postfix-3.8.6v0-sasl2-pgsql fast, secure sendmail replacement

That would probably be handy.

> Second topic: pkg_add postfix%snapshot works well, but can't this way to force to install a given flavor:

You're hitting some default-case handling by using %snapshot because
that ports subdir no longer exists.

postfix--ldap%stable
