Is there any problem with new email messages going to to this sssd-users mailing list?

I sent an email 6 days ago and again re-submitted it 4 days ago, about 

      sssd auth against AD working;  sssd autofs against LDAP / rfc2307bis not working.

to date, I have not seen it appear in this sssd-users mailbox yet.  I'm flummoxed on the problem and need help from people more knowledgeable than me. 

The mail message wasn't in violation of any mailing list policies (wasn't excessively long, etc).  The above subject line might be slightly long, but I don't think that'd be a problem.

I realize these sssd-user mailing list maintainers are frequently out for 2-3 days, due to their job roles,  but I've seen other email responses on this mailing list since then.
