For our servers to relay outbound e-mail you must enable authentication. Please see our tutorials for help configuring your client. Our servers support the PLAIN and LOGIN authentication methods.

All outbound e-mails must be relayed through our servers. If you do not use our servers for outbound e-mail you risk having your messages rejected by the recipient’s e-mail server. This is because OnionBit publishes SPF and domainkey information that some e-mail servers use to verify that messages claiming to be from onionbit.com originated on a server authorized to represent onionbit.com. We recommend using port 587 and enabling STARTTLS for outbound SMTP access.

If you need help configuring your e-mail or instant messaging client to use these settings, please try one of our tutorials. If your client is configured correctly and you’re still having problems, please visit our troubleshooting page for hints. You can also use our contact page to ask the OnionBit Support Team for help.
