I think this probably means that you sent an empty string to the SMTP server.

Make sure that none of your teams have line channels in them.

Can you register a transaction and insert a copy of the log?

see here for details on registering http://swiftmailer.org/docs/logger-plugin

I got this when I had the wrong setting in the factory.yml file as shown below.

class: Swift_SendmailTransport

But it should be the following.

class: Swift_SmtpTransport
