altering "from" field contact form

Hi there!

I have an issue with sending emails. From field looks wierd and different on different hosts:

Examples:
1. Site name email configured in contact module settings in between less than greater than [email protected]
2. =?UTF-8?B?bunch_of_random_letters_/[email protected]

How and where could i set/alter from field to be like

[email protected]

?

Thanks

Any help would be much appreciated
