Hi 

I have bee using openerp for some months and never have had problems sending mail out. Today I started noticing that mail sent was not being delivered. So I went to test the outgoing server. I got an error, I changed to a gmail account and got the same error. Please assist if you can. This is the error:

Here is what we got instead:
 -3
Temporary failure in name resolution
