My understanding (and again, I know very little about these things) is that the two programs are roughly equivalent: they handle creating and checking TLS certificates, and creating and handling TLS-encrypted connections to remote servers. I actually was just assuming you are using gnutls, you can probably check the libgnutls-version. You can also try setting gnutls-log-level to 3 or 4 and fetching mail, and see if anything interesting pops up in *Messages*. The bad news is that I tried this: gnutls-cli --port 995 pop.zoho.com And it connected just fine. You might try that, and going through with the login procedure. Otherwise, I might be fresh out of helpful! Eric
