Sending an e-mail fails a few times and then the mail is sent. On the right side of my laptop this message pops up: Het certificaat van imap.ziggo.nl komt niet van een vertrouwde bron (The certificate from imap.ziggo.nl is not issued by a reliable source). How can I remedy this situation?

Dit kan samenhangen met een antivirusprogramma/firewall. Gebruikt u dit en zo ja, welke? Zie https://support.mozilla.org/en-US/questions/1192349
