No its not T.38 pass through. T.38 pass through is only if the 2 end
points negotiated T.38, i.e. a provider that supports T.38 and an ATA
that supports T.38. What you are describing will most likely fail if
there is any VoIP in between, and should succeed over pure TDM using
digium or similar cards.

asterisk doesn't have the ability to send or receive emails. It does
have the ability to use something like sendmail to send/receive
emails.
I'm assuming its a typo and you meant faxes.
What exactly are you trying to accomplish? If you need to know
something go ahead and try/test it and report back. After all that is
what we all did to be able to answer it. Apparently the fact that
others tried it and told you that it works still warrants a
question:"I need to know if this is true"

I assume you meant than not then, but I'm not sure if its a typo, you
might just not know.
app_fax.c does faxing. The question is what are YOU trying to do?
