Email is a massive part of my
N95 8Gb's duties.
Not necessarily composing, but certainly reading and responding. I have tried just about all of the email solutions available for the
N95/Symbian.
I have kind of settled on SEVEN system's beta push email. It integrates into the phone nicely and seems 100% reliable.
I also liked Profimail, but it wouldn't push and was hit and miss at sending.
Emoze was poor (In my opinion) and took an age to connect and stay connected. Unreliability is the main reason I ditched this. I also used the phone's native client, but it was clunky. Also, if it tries to poll a certain number of times without sucess, it removes the scheduling.
So far, SEVEN seems fast and reliable. I use Gmail and Yahoo with this. Both Push well.
