Email issues, relay failure

[Bender, Chris]

How would I whitelist SMTP speakers?

I am thinking it would be ok to reload the rules, would that clear the
issue with SMTP users for now?
Whats the harm?
Thanks

Any pf.conf file I've ever seen does something sensible  after reload. 
I suspect one could write something perverse that blows up on restart, 
but that would making rebooting the machine problematic....

pf can load data from files when it starts or just manage things in a 
fashion that is transient upon restart.  Hard to say what's happening in

your case w/o a clue as to what's in pf.conf.

I'd suggest that you at the very least whitelist internal SMTP speakers 
that you expect to get e-mail from on a regular basis, even if you do 
throttling of SMTP connections in general.  Much less messy....
