Help Upgraded firmware to latest now Email is all messed up

[silicuda]

I upgraded to the latest firmware, by doing so I also got Ice Cream Sandwich on my phone now. Upgrading broke my email, I first noticed that it sent all kinds of random emails to people in my contact list, and secondly it doesn't let me send emails. I type it, press send and it never delivers them, nor do they show up in sent messages.

How do I fix this? I am using GMAIL accounts on Push configuration.

Thanks
