I've made a little application for email parsing for a certain niche of business. That requires access to the user's email. I currently have a small settings menu where I ask the user to enter the relevant information for this, mail server, protocol, port, email and password. The problem is I'm dealing with a clientele that is not at all computer literate and asking them to go on their email providers site and find this information is a headache for them.
How much info can I get myself just from the email? Can I somehow track down the relevant info (mail server, protocol, port) myself so I can help new users config their system?
Of course this is easy if they use a big email provider like gmail or hotmail, but some of my customers have their own websites and email server (usually by paying a third party to set them up 2 years ago and are unlikely to have the information necessary/understand how to go on the hosting service website and get the email server info).
