I'm trying to run davmail on two very similarly configured
Fedora 34 computers. I downloaded a recent .zip from
sourceforge, which I unzipped it into a ~/.davmail directory
on each machine. To run davmail, I cd into that directory,
and run "./davmail davmail.properties".
The only difference between the two property files (now), is
that one now has a refreshToken (davmail worked). I have
enabled SSL pointing to a keystore file, davmail.p12. That
file is different between the two machines, one has a
LetsEncrypt certificate, the other a DigiCert certificate.
On one machine if I run:
openssl s_client -showcerts -connect fqdn:port
it works fine. I can use this davmail instance and get my
email from the remote imap server.
On another machine I get an openssl error
140485856540480:error:1408F10B:SSL routines:ssl3_get_record:wrong version number:ssl/record/ssl3_record.c:331:
which seems to indicate that davmail is either not accepting
tls connections, or is using the tls version.
Is this a davmail problem, or maybe different java
configuration or security between the machines?
Is there a quick way to check this independently of using
davmail?
