for gmail OJS 3.0.0-8

I am getting a generic “could not connect” error and a link to the PhPMailer git repo.

Address and passwords are correct

Hi @candelariajr

Have you tried directly connecting to on port 587 from your OJS server? The telnet command would suffice:

telnet 587

If that doesn’t work, then the problem may lie in outgoing connections, and you may need your system administrator or network admin to get involved.
