I have been using the toaster for years now. I have upgraded many times, but I have never seen this problem before. When certain providers email to me they received the message Deferred: 403 4.7.0 TLS handshake failed The only difference is I pulled out my hard drive from a slower machine and put it in a new machine. Everything is working just great except for this problem. One of my clients is going to leave unless I fix the problem, but I don't know where to start. I cant find any topics that directly look at this. Some say my server is broken and others say it the MTA they are sending from. Can anyone help me out on this one? Thanks.
I'm going to guess its related to something with OpenSSL and the differences in CPUs between the boxes. Rebuild OpenSSL with the latest version and then rebuild qmail and see if that doesn't fix it.
