I developed an application which checks mail(gmail) all the time and alerts me whenever new mail has come. In short its a email notifier or email alerter.
The application uses IMAP protocol .The application opens the connection once and it continously checks whether a new mail has come. My doubt is , since the connection (or port) is opened all the time , is there any chance of security threat. I mean to say , is my connection secured. Is it safe to keep the connection open all the time?
I dont want to open and close the connection every time with short time gaps.
So how far can i rely on this? How to ensure security ? Is security all ready ensured by the protocol?
