Hi,
I have my CentOS7 sendmail configured to relay outgoing system e-mail through my gmail account.
The setup recently stopped working. Gmail SMTP keeps returning "service unavailable".
I think it has something to do with the recent changes in Gmail authentication procedures.
Does anyone know how to make the relaying work again? I could not find anything on the Net.
