The connection to 127.0.0.1:125 (your MTA) stucks in SSL-renegotiation. ASSP as a SSL-client does not request a reneg - and your MTA should not. Why you use a SSL-connection for localhost? Does this make sense?

One had a delay of 53 minutes, the second one almost 6 hours. I don’t see a pattern. Von: Dirk Kulmsee <d.kulm...@netgroup.de> Gesendet: Montag, 16. Dezember 2019 14:17 An: 'ASSP development mailing list' <assp-test@lists.sourceforge.net> Betreff: Re: [Assp-test] TLS connections getting stuck Thanks for your quick reply Thomas, ConTimeOutDebug was already switched on. Now I additionally set connections logging to diagnostic. Then I sent 3 identical mails with only one word of text from gmx.de for testing, 1 got through immediately, the other 2 timed out. The timeout appears during SSL renegotiation.

This happens with several different servers (e.g. from gmx.net, t-online.de) but it does not always happen. Most mail flows smoothly. I am using an official SSL certificate (Digicert wildcard), SSL_version and SSL_cipher_list are set to default. ASSP forwards mail to a Postfix on the same machine, port 125. Here are some log lines: Dec 16 11:54:32 localhost assp.pl[115465]: [Worker_1] Worker_1 wakes up Dec 16 11:54:32 localhost assp.pl[115465]: [Worker_1] Info: Worker_1 got connection from MainThread Dec 16 11:54:32 localhost assp.pl[115465]: [Worker_1] Connected: session:7FA1F68F3B30 212.18.1.53:33523 > 192.168.12.242:25 > 127.0.0.1:125 Dec 16 11:54:33 localhost assp.pl[115465]: [Worker_1] 212.18.1.53 Disabled SMTP AUTH for External IPs Dec 16 11:54:33 localhost assp.pl[115465]: [Worker_1] 212.18.1.53 info: got STARTTLS request from 212.18.1.53 Dec 16 11:54:33 localhost assp.pl[115465]: [Worker_1] SSL-DEBUG: .../IO/Socket/SSL.pm:1578: start handshake Dec 16 11:54:33 localhost assp.pl[115465]: [Worker_1] SSL-DEBUG: .../IO/Socket/SSL.pm:1030: starting sslifying Dec 16 11:54:33 localhost assp.pl[115465]: [Worker_1] SSL-DEBUG: .../IO/Socket/SSL.pm:1077: Net::SSLeay::accept -> -1 Dec 16 11:54:33 localhost assp.pl[115465]: [Worker_1] SSL-DEBUG: .../IO/Socket/SSL.pm:1077: Net::SSLeay::accept -> -1 Dec 16 11:54:33 localhost assp.pl[115465]: [Worker_1] SSL-DEBUG: .../IO/Socket/SSL.pm:1077: Net::SSLeay::accept -> 1 Dec 16 11:54:33 localhost assp.pl[115465]: [Worker_1] SSL-DEBUG: .../IO/Socket/SSL.pm:1125: handshake done, socket ready Dec 16 11:54:33 localhost assp.pl[115465]: [Worker_1] SSL-DEBUG: .../IO/Socket/SSL.pm:1578: start handshake Dec 16 11:54:33 localhost assp.pl[115465]: [Worker_1] SSL-DEBUG: .../IO/Socket/SSL.pm:757: ssl handshake not started Dec 16 11:54:33 localhost assp.pl[115465]: [Worker_1] SSL-DEBUG: .../IO/Socket/SSL.pm:802: not using SNI because hostname is unknown Dec 16 11:54:33 localhost assp.pl[115465]: [Worker_1] SSL-DEBUG: .../IO/Socket/SSL.pm:3093: get_session(127.0.0.1:125) -> none Dec 16 11:54:33 localhost assp.pl[115465]: [Worker_1] SSL-DEBUG: .../IO/Socket/SSL.pm:850: set socket to non-blocking to enforce timeout=5 Dec 16 11:54:33 localhost assp.pl[115465]: [Worker_1] SSL-DEBUG: .../IO/Socket/SSL.pm:863: call Net::SSLeay::connect Dec 16 11:54:33 localhost assp.pl[115465]: [Worker_1] SSL-DEBUG: .../IO/Socket/SSL.pm:866: done Net::SSLeay::connect -> 1 Dec 16 11:54:33 localhost assp.pl[115465]: [Worker_1] SSL-DEBUG: .../IO/Socket/SSL.pm:921: ssl handshake done Dec 16 11:54:33 localhost assp.pl[115465]: [Worker_1] SSL-DEBUG: .../IO/Socket/SSL.pm:2970: callback session new <127.0.0.1:125> 140333579019952 Dec 16 11:54:33 localhost assp.pl[115465]: [Worker_1] SSL-DEBUG: .../IO/Socket/SSL.pm:3040: add_session(127.0.0.1:125,140333579019952) Dec 16 11:57:44 localhost assp.pl[115465]: [Worker_1] [TLS-in] [TLS-out] 212.18.1.53 TLS-Connection idle for 180 secs - timeout Dec 16 11:57:44 localhost assp.pl[115465]: [Worker_1] [TLS-in] [TLS-out] 212.18.1.53 [SMTP Status] 451 Connection timeout, try later Dec 16 11:57:44 localhost assp.pl[115465]: [Worker_1] [TLS-in] [TLS-out] 212.18.1.53 disconnected: session:7FA1F68F3B30 212.18.1.53 - processing time 0 seconds Dec 16 11:57:44 localhost assp.pl[115465]: [Worker_1] Worker_1 will sleep now The IP mentioned here ends up in SSL-failed-cache.
