Sending Emails from SMTP
Everytime I try send an email (from both a client such as thunderbird and mailbox url), I receive the below error and am unable to send any emails.
"Wrong or missing login data to access e-mail transport server smtp.mailbox.org. Please check associated account's settings/credentials."
Does anyone know how to fix this so I can send emails?
PS: Receiving emails works as expected.
Any assistance would be greatly appreciated.
