I already using zoho mail service, could it be the reason.
Every thing I work on ubuntu 17.04
Thanks for any help.

It looks like you have connection problems try this command
nc -zv 209.85.201.26 25if it times out then you are being blocked by DO.Also make sure to use latest LTS version from ubuntu that is Ubuntu 16.04, 17.04 will end its life in three months from now.
hi Mohsen.
it seem to be I'm being blocked by DO. How can I fix it.
Thanks anyway.
