I've already had this camera for three months. And it haven't yet sent a single message!

No matter how I tried I could not make it work. Different settings, different mail services...
It's always the same:
Can not connect to SMTP server.I connected to it via Telnet and tried to ping smtp.gmail.com.
# ping smtp.gmail.com
PING smtp.gmail.com (2a00:1450:8005::6c): 56 data bytes
ping: can't create raw socket: Address family not supported by protocolMay it be due to my router (Linksys WRT54G2)?
On the other hand, smtp.yandex.ru is pinged successfully, but still doesn't work.

What else can I try? Is my situation hopeless?
