Why are some mobile operators blocking IMAP?
IMAP is a very useful protocol for collecting and sending email. It is the defacto standard for corporate email Microsoft Exchange servers. Nokia have released apps for their S60 series phones that can connect to exchange servers via IMAP. For a variety of security reasons corporate entities often choose to have IMAP access only to their email systems.
Therefore It was very annoying to discover that the Irish mobile phone operator three do not allow IMAP access from their handsets. They only allow POP access, why is this the case?
My professional opinion cannot fathom a reason for this short sighted approach.
I'm connecting to an IMAP server on my 3 handset - only problems are when you try to use IMAPS e.g. gmail.
