In general, email is moving to encryption with SSL/TLS. I'm not sure about the "in general" in that. We process a lot of email daily, 99% is unencrypted. I'd have to check the logs to see whether there's been any growth in TLS usage.
Many email providers are now supporting or even requiring SSL/TLS. Supporting definitely, but that's not really new. Well, I don't think so, I'm still checking the logs. Requiring TLS - I haven't seen (m)any of those, except those that specifically offer secure services.
IIRC, GMail requires it.
StartTLS is one method of doing that. It's the only one I know of unless you encrypt the entire network (IPsec, VPN) which doesn't really make sense for email, unless you're on a closed network. The other method is to use specific ports for SSL/TLS. Do you have some info on how that works with any arbitrary email host? I see no support for that in e.g. postfix. It's all STARTTLS.
In Seamonkey & Thunderbird, you can specify connection security with the choices none, starttls and ssl/tls. You can also specify the port number to be used.
Yes, but that is only for mail submission, not for mail exchange between two mail servers. -- Per Jessen, Zürich (7.1°C) http://www.dns24.ch/ - free dynamic DNS, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
