the email account
ISFQuebec@isfquebec.net comes from I don'T know where, this happened since 1.5.25,
ISFQuebec being my User credential, to access the device,
Now if I change my Login User to admin it works fine,
It looks like the User name has to be a valid e-mail adresse for this to work, Not very good for us,
Thank you for guiding me to make it work again,

This is not simething that changed on our side, mail host have adopted new security protocols that our switches dont deal with.
Overview:
New email security requirements, driven by Google, Yahoo, and Microsoft, mandate bulk senders (>5,000 emails/day) implement SPF, DKIM, and DMARC for authentication.
These requirements present many hurdles. Right now all developers are working to complete the WS4 line.
Our current plan to adopt in WS4 then back port to WS line in Q1 hopefully. Basicaly we will use send mail on the swith and send the emails directly from the switch then all the user has to do is create an SPF1 TXT record in DNS. However if your switch does not have internet access which is best then the operator must have an internal mail server that the switch can get to via non internet access via internal invalid routes.
Another thing i am considering is removing email alerts altogether. For one switches should not be internet accessible and most WISPs no longer host their own email servers.
This is a complex issue with a lot of moving parts and security concerns.
