Problem regarding VoiceMail notification

hello dears.

I had a great support from the forum. I am using Trxibox2. My ISP email server is mail ayza.net. After configuring my asterik1.local as valid account to my email server, i could mail to the local mail account. but the i could not send the mail… yahoo, hotmail etc…

what would be the solution??? can you tell me out?? I made changes to
sendmail.mc as well such following:

define(SMART_HOST',mail.ayza.net’)dnl
MASQUERADE_AS(`ayza.net’)dnl
MASQUERADE_DOMAIN(localhost)dnl

Even i have the hosts address asterisk1.local to asterisk1.ayza.net

127.0.0.1 localhost
127.0.0.1 asterisk1.mail.net

and have reconised by my mailserver and DNS as well…

but it still shows

help plz,

sultan
