Several related questions to phone to server mail sending security and syncronization
Posted on 2011-05-02
I have a customer who wants to be able to send and receive email THROUGH their firewall to their mail server (Imail 11).
Aside from changing the default port the mail is being sent and received on, how does using SSL technology prevent hackers who stumble upon the mail server from "relaying" mail through the server if theyre able to correctly guess username and password for an account? My assumption is it doesnt.
Aside from encrypting the text so it cant be read as it passes through the Internet, what benefit does SSL provide?
The mail server software allegedly supports Activesync, but I cant make it work with any of our phones (Iphones and Androids only). How is activesync different from just allowing POP3/SMTP to the phone client?
Lastly, assuming the default ports for POP3 and SMTP (995 and 465) are used, what other ports would need to be opened on the firewall for an SSL solution to work? for an ActiveSync solution to work? Does anyone have a good guide to either?
