Multiple sender and recipient in emails

[nickybad77]

Hello. I'm writing this topic, having looked around without finding a solution. On my Samsung Galaxy S i9000 with Android 2.2 Froyo update I'm getting few quirks with e-mails. Whenever I send an e-mail with the default application and look at it on a web based client like Gmail or my e-mail client (Mail) on my Macbook, the header of the e-mail has the sender (myself) and recipient(s) repeated 3-6 times.
It always look as:

From: myname
Reply to: myname
myname
myname
myname
myname
myname
To: recipient1,
recipient2,
recipient1,
recipient2,
recipient1,
recipient2,

Is there anyone who had the same issue and solved it?

Many thanks
