Hi erverybody, I have problems getting a SSL connection from Exchange to our SMTP server, which is using OpenSSL as SSL library. The direction to Exchange is working fine, but the other one has problems. I debugged it for a while and it seems that the problem has something to do with the state "check for second client hello". The function ssl3_check_client_hello(s) returns -1. I believe, that somehow our server awaits the second hello from Exchange, but it does not arrive. I found a Microsoft bug, which can be eliminated by setting the options (SSL_OP_MICROSOFT_BIG_SSLV3_BUFFER), but it does not affect the problem. Does anyone know this behaviour? Thanks a lot!
