Hi I'm new to this forum and am looking for some help with emails if possible.

I have set up various email accounts on my HTC EVO3D handset and i have noticed that when i create a new email and send it from the handset it sends the email normally with my signature underneath the body of the text however when i reply to an email i have recieved the email sends okay but the signiture follows straight after the text of the email without any spaces ? It looks awful ? is there any reason why the signiture does not stay at the bottom of the email like it does when creating and sending a new one ?

Thank you in advance
