I'm using sendmail server ver 8.12 and I want to send to a cell phone
using this format (10 digits number@cell phone comany )
here the problem :
- if I send from gmail to the same number it receive it without any problems
- if I send from my sendmail server nothing happen and nothing in the log file
even I increase the log leve it didn't give me any more details, but it send to any other regular email
- if I send from another sendmail server ver 8.14 ir receive it right away

is it the sendmail version, or there other thing I should add it to this server??

Thanks for your help and suggestions
