Failure sending notification

[xavi@…]

I'm getting the following error when adding a new ticket or changing an existing one. I'm running 0.9.4 an my trac.ini [notification] section looks like:

[notification] always_notify_owner = true smtp_always_cc = xbeumala@… smtp_password = ctvdev05 smtp_enabled = true smtp_replyto = xbeumala@… smtp_port = 25 always_notify_reporter = true always_notify_owner = true smtp_server = mail.communi.tv smtp_from = dev@… smtp_user = dev@…

Here's the error.

21:59:03 Trac[web_ui] ERROR: Failure sending notification on change to ticket #6: (-2, 'Name or service not known') Traceback (most recent call last):

I've been looking into another similar tickets, but doesn't seems to work for me.

Thanks a lot for your great work!
