one that I don't remember now). There are also unix php scripts that
don't work properly with it.
Also earlier versions of postfix did not properly retry delivery if the domain had no MX and connection to they server did not work. Other mail server may also have various types of "unusual" behavior when they see
no MX. Also some servers like exim have option not to send email if
there is no MX record (or rather turn off default behavior of falling
back to A record if MX is not there).
So having no MX server is really not such a good idea nowdays...
Obviously FEMA's problems are a lot worth since ip address 184.108.40.206
is behind firewall and does not accept port 25 connections.
