However, when i'm using smtp.gmail.com, it works !

Did you figure out how to work around this? I'm receiving the same error.

i have no experience with gsmtp. can you try a different email service?

[manntam]

I ended up changing to normal smtp.gmail.com and it works like charm.

Not sure what is going on with the smtp-relay
