We have an Exchange 2003 SBS (SP2) and want to handle also our secure e-mail through the server. Usually we don't use the POP3 connector. Of course from the provider of the e-mail we get only configuration infos for e-mail clients, not for servers. Now I want to get the post and, I think harder, I want also to send SSL e-mails through the server. My idea (I do not know if possible) is that, from within Outlook, I use an other user as sender (from...) and then automatically starts the e-mail through the secure channel.
We do not want to send every e-mail through the secure channel, because the have a lot of other limits and a high cost.
The infos that I get from the provider are these:
e-mail server for incoming: POP3/IMAP, name: mbox.cert.legalmail.it. It needs a protected connections and uses the POP3S port (995) or IMAPS (993).
Server for outgoing: sendm.cert.legalmail.it. I need to comunicate through SSL (port 465).
Further they have a public certificate that they use for signing the e-mails (I do not think that this is a problem).
Of course my scope is that everything works through the server and that I have not to install/configure anything on the client side. I understand that I can handle the POP3S with the server and the SMTPS part with local Outlook client, but this is not what I wish.
The question is not very urgent but I think not easy.
Of course I would prefer to use free products (including the POP3 Connector delivered with SBS) but I accept also answers where I have to buy third-part products. In this case I look for tools that make only this, I do not accept to buy with this POP3 Connector 5 other services that I don't need or already have covered with other products (i.e. Fax, Antispam, Antivirus, e-mail recording, ecc.)
For a full resolution full points, for a parcial (only POP3S with a free tool) half points.
