Hello everyone, TL;DR -- change your incoming and outgoing email servers to mail.cgl.ucsf.edu I goofed and accidentally cancelled the update to our email certificate. So we have an expired certificate with email right now. And that might make your email client might unhappy when sending email or viewing email. So while we recommended using plato.cgl.ucsf.edu for both your incoming and outgoing email servers (incoming uses the IMAPS or POP3S protocol, and outgoing uses the SMTP protocol), you can workaround the problem by setting it to mail.cgl.ucsf.edu (because I borrowed the webmail server certificate). mail.cgl.ucsf.edu limits you to a single host in the plato cluster, but it will work without complaint. We should get a replace certificate within a few days. mail.cgl.ucsf.edu will continue to work when that happens. Our email certificate also includes email servers that don't run webmail. And if you're not asleep yet, having an out of date certificate for email servers doesn't stop email from being delivered. There are just warnings in the log files. I suspect that will change as the Internet gets more paranoid. My apologies, Greg
