I guess it means that the client couldn't verify the Certificate
Authority and didn't bother to ask you if you wanted to trust it anyway
(which most clients do nowadays). So you'll probably need to figure out
a way to import your CA cert (or self-signed cert) to the vodafone.

See http://wiki.dovecot.org/SSL/CertificateCreation for more information
about CA certs and self-signed certs and their problems.
