Problems sending mail
I've just made five trial accounts to test the functionality before paying and I'm having 2 problems already. First, I'm unable to send any attachments at all from the mailbox.org webmail (Error: "Wrong or missing login data to access mail transport server smtp.mailbox.org. Please check associated account's settings/credentials.") and second, I'm unable to send any mail at all, with or without attachments, from Thunderbird (Error: Failed due to unexpected error 80004005. No description is available. The message could not be sent using Outgoing server (SMTP) smtp.mailbox.org for an unknown reason. Please verify that your Outgoing server (SMTP) settings are correct and try again."). I'm using Windows 10, if that helps. I've seen other posts, a lot of them, saying that getting locked out of your account by spam filters is very common on mailbox.org, so if this is still a problem, could please let me know? Dependable email service is crucial in my line of work. Thank you! UPDATE: I'm finding I can't send mail, even without attachments, to even mailbox.org email addresses. So no sending mail at all.
