Email to IM errors

Hi!

I just tested this feature with a friend. She sended me an IM while I'm logged out from SL, and I try to reply them from my email.

In fact my friend has received some of my emails as IMs, but for the most part I keep receiving this kind of mails when I try to answer her IMs:

"This is the Postfix program at host data.agni.lindenlab.com.

If you do so, please include this problem report. You can

¿Could they be caused by the fact I'm using a gmail account?

Thanks in advance!

Mmm... not sure if I'm the only one suffering this issue... or if it has been answered elsewhere. Can anybody help me to find what I'm doing wrong?
