For our servers to relay outbound e-mail you must enable authentication. Please see our tutorials for help configuring your client. Our servers require TLS, and 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 Lavabit publishes SPF and domainkey information that some e-mail servers use to verify that messages claiming to be from lavabit.com originated on a server authorized to represent lavabit.com. We recommend using port 587 for outbound SMTP access.
If you need help configuring your e-mail 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 frequently asked questions page for hints. You can also use our contact form below to ask the Lavabit Support Team for help.
