guessed, thank you very much Randall ! After I installed the Server and CA certificate (selfsigned) proper, it starts working with Outlook and Eudora. (there are still one additional step required for Eudora). But (to make a long story short) there are now some "new" qpopper debug-messages, I can't really understand. For Every TLS/SSL connection (this is true for both ports, "alternate" and "stls") I found the following messages at the end of the tracefile: Oct 9 12:10:13.521 2001 [24910] SSL_get_error says SSL_ERROR_SYSCALL (5) [pop_tls_openssl.c:766] Oct 9 12:10:13.521 2001 Oct 9 12:10:13.521 2001 [24910] TLS shutdown Error [pop_tls_openssl.c:789] Oct 9 12:10:13.521 2001 Oct 9 12:10:13.521 2001 [24910] freeing m_OpenSSLconn [pop_tls_openssl.c:811] Oct 9 12:10:13.521 2001 Oct 9 12:10:13.521 2001 [24910] freeing m_OpenSSLctx [pop_tls_openssl.c:817] Oct 9 12:10:13.521 2001 Oct 9 12:10:13.521 2001 [24910] openssl_shutdown returning -1 [pop_tls_openssl.c:822] Oct 9 12:10:13.521 2001 Oct 9 12:10:13.521 2001 [24910] (v4.0.3) Ending request from "hg6522" at (chaos.dvz.fh-giessen.de) 212.201.18.85 [popper.c:368] Oct 9 12:10:13.521 2001 What means TLS shutdown error ? Why it can't close the connection proper ? Can this cause difficulties in certain circumstances ? If I only consider the Client-Side, it seems to work perfectly. I would be deeply grateful if someone could give me a clue (which me not refer back to the sources). regards - oliver n o t e i n t h e m a r g i n : The only tick, I can see on the Client-Side, comes from the "Eudora SSL Connection Information Manager" it says: ***** Unknown certificate chain validation error: Code(3015) ***** ***** But ignoring this error because Certificate is trusted ***** I suppose that this message appears, cause I am unable to install the CA Certificate for Eudora (but this is no QPopper subject). Outlook shows no messages at all (excepting the E-Mails :-} ... ), but I did't discover the "trace-capability" of Outlook as yet ...
