As you may know, Vultr block SMTP port for new user. I'm student and use PayPal (verified with gift card) and have no real CC. So I change every Wordpress notifications to local mail, like "firstname.lastname@example.org" and "email@example.com". I can read it via SSH, but I can't read HTML email properly. So I thinking to use webmail like Horde/SquirrelMail to read every incoming mail ("firstname.lastname@example.org"), or maybe read it with mail client like Thunderbird. Is this possible?
