Hi, I already tried this but after a double check I saw that it was not set correct to 0s. Now it is working and also the connection is possible, around 5 seconds faster.
No idea why this setting is set as default. It hink there will be many problems with this. What a research to find the iroot cause.

The web application probably hits a timeout before the connection is established. This attempt was made from the web application's host? Did you also try a manual handshake test with telnet? Would be interesting to know at which stage these long waits occur. What about Wireshark? Were you able to analyze a network trace? > Exim version 4.82 uid=0 gid=0 pid=4897 D=fbb95cfd [...] > 4901 doing ident callback > 4901 ident connection to x.x.x.x failed: Connection timed out You probably should disable ident lookups, I don't see why anyone would need those today and by doing so you get rid of a few seconds of waiting. What's rfc1413_query_timeout set to in your configuration? Maybe this explains the ~6 seconds connection time. Apart from that I cannot find any issues in this debug trace.
