[solved] 451 Internal server (Email)

[dokithonon]

Hello,
Sometimes when using Email.send I have this error
response : 451 Internal server
code : EAUTH
command : AUTH PLAIN

Some people say that we should keep the smtp handle open : Error: Invalid login: 451 4.3.2 Internal server error · Issue #994 · Mailu/Mailu · GitHub

I am using the regular Email package. Is there a way to avoid this errors ?

Thanks

It seems that the problem was coming from my smtp provider
