--- Comment #2 from Axel Reinhold <e...@freakout.de> ---
OpenSSL 3 is API compatible to OpenSSL 1. dovecot, haproxy and apache did the
transformation 1->3 with the same build-scripts without problems.
You are right - exim just refuse to talk TLS at all - but Why? There ist the
same Makefile and the same configure file used. The root cause and the only
hint for the problem is the error in the log for which i couldn't find anything
useful in the net:
log in mailmainlog on the server side:
2025-03-22 17:01:51 TLS error on connection from pie2.ypack.de
(mail.example.com) [188.138.31.227]
(SSL_CTX_set_option(0x42004000)): error:00000000:lib(0):func(0):reason(0)
2025-03-22 17:01:51 SMTP call from pie2.ypack.de (mail.example.com)
[188.138.31.227]
dropped: too many syntax or protocol errors (last command was
"?\026?\024?\035?\027?\036?\031?\030
\001?\001\001\001\002\001\003\001\004?#???\026???\027???\r?*?(\004\003\005\003\006\003\b\007\b\b\b
\b", C=EHLO,STARTTLS)
exim seems to call a SSL function with wrong parameters for me, and then
openssl refuses to talk. I did not find configure options to control the call
to SSL_CTX_set_option() - and i could not find any hints for the
SSL_CTX_set_option call from exim in the net.
