Hi @Sufyan_Sher

This isn’t an OJS problem, and you may need to reach out to Google for a resolution:

i m not getting help from this i also contacted with my hosting provider they crystle that its not from their end

We experienced the same problem when updating the system. We created a new server, with the most updated OS, php and postgres.

I talked to some technicians, and they explain that as a new server was made, the new server IP was not added to the list of IP’s that allow sending email from the Virtual Machine.

Added the new IP, it worked.
