Okay.  Easily done.  You can find instructions on the website (HOWTO).

You are correct, although my advice would be to have that mailbox only 
be accessible by one individual (or position, like "receptionist"), and 
that individual then forwards them.  It causes a lag in delivery 
sometimes, perhaps, but it helps protect sensitive information, keeps 
the users from deleting faxes that were intended for others, and saves 
in duplication of fax handling by more than one person.

HylaFAX is a fax server, not a mail server.  So your SMTP will be what 
accepts e-mails.  You can make your SMTP server pass them on towards 
HylaFAX, and given how you do that, yes, HylaFAX can send faxes that 
originated as PDF or TIFF attachments.

faxmail doesn't natively work with PDF attachments.

No developer has actively worked on faxmail for a very long time.  I'm 
not sure any developers actually even *use* faxmail.

I do all of my email-to-fax gateways with a shell or procmail script.

That said, I think that email-to-fax gateways are a less-than-ideal way 
to do the job.  I've found that web application pages (e.g. in PHP) are 
better for security and for post-submission handling (e.g. altering or 
cancelling the fax, or checking up on the status).

Can be done.

I've written so many different email-to-fax scripts in procmail and 
shell that I would have incorporated something already into HylaFAX 
proper if I felt that it was worthy of it.  However, for all effects 
and purposes, these scripts are mere customizations.  Every person 
seems to want the e-mail handled slightly differently, and it's much, 
much easier to just rewrite the script to handle the customizations 
than it is to make the script "customizable" with some configuration 
file of some kind.

Good luck on getting anyone to guarantee 100% reliability.  Look to the 
HOWTO for recommendations on good modems to use.
