smtp failure with few providers

smtp failure with few providers

Hello,
I have few laptops users which need to send mail when there are in hotels, 
lounges, customers wifi access, ...
Problem is now, lots of providers blocked usage of external smtp servers so 
my users receive mail but can't send mail.
Because I manage my company mail server, I 'd like they use my smtp server.
How can I setup clients and server to use providers internet access with my 
smtp server ?
Thank's

If they use Outlook Web Acces or Outlook Anywhere then they would have no 
issue.  What version of Exchange are you running?

if they are already authenticated users, so you can either configure RPC
over HTTPs for the server and the client, in this way the clients will use 
the MAPI not POP or SMTP.
the bellow link give you the steps to configure RPC over Https
