vivaldi in mail app on iphone IMAP/SMTP settings

[andrewDavis]

Does anyone know the incoming and outgoing mail servers for vivaldi? I'm trying to set up vivaldi through the mail app on the iphone but its having issues with outgoing mail server, I keep getting server rejected recipient's address . so far I have tried mail.vivaldi.net and smtp.vivaldi.net

Same issue. Driving me insane. Works perfectly well on my Android phone. On iPhone, however, I can only receive mails and not send them using vivaldi smtp. Tried everything playing around with settings.

That are the servers:

smtp.vivaldi.net / Port 465 / TLS
imap.vivaldi.net / Port 993 / TLS

I do not know if your iPhone has latest SSL certificates for Let's Encrypt.
