Relaying disallowed error
When the email address (or login credentials) you have provided in the application does not match the email address (or credentials) of your account's outgoing server, you will see a 'Relaying Disallowed' error when you attempt to send an email. The SMTP client will not be able to send the email because of the email address mismatch.
This can happen when an email address is used as default in a coded program or when you have misspelled the email address while configuring your email inbox. You will receive emails without any issues. To resolve the 'Relaying Disallowed' error, you need to correct the email address provided.
