Title: Re: [Openvpn-users] Road Warrior email sending (Off-Topic)
Not really off topic. At least not more than any other "I have wrong routing" posts.
For help :
 - client and server ovpn config files
 - network topology
 - network settings of non-vpn interfaces (on client and server)
 - where is the mail server located ? what protocol does it use ? what is the error message you get ?

Les -

    Thanks for the explanation.  Unfortunately it doesn't appear to help my
situation.  We do not run a mail server at our office.  Our incoming mail
service is provided by a third party provider.  Our outgoing mail service is
directed to the mail server at our local DSL provider.  All incoming and
outgoing mail for the PC clients in our office therefore does not go through
our server.  My employee would love to be able to use her regular Windows
Mail client when she is accessing the internet from wireless connections at
hotel meeting rooms.  If anyone has any other suggestions for me you can
send them directly to me and we can take this off-list, since we are clearly
off topic now.  Thanks.
