Can't connect to SquirrelMail with Mac OS X Mail client
I am working with an organization whose email is running on SquirrelMail. When I try to set it up as a new account in my Mac OS X Mail client, I choose IMAP, enter the email server name, password, etc. but once the account is created I keep getting the message, "Mail can't connec to the account... Enter the password." I have checked and double checked that the password is correct because I can log onto the account via the webmail portal. Any ideas on special configuration settings necessary for SquirrelMail on the Mac OS X Mail client?
