Problem with rt-mailgate SSL

I’m getting the following error when trying to test rt-mailgate and have not been able to figure out the problem.

[root@newreef tls]# echo “This is a test” | /etc/smrsh/rt-mailgate --queue support --action correspond --url --debug

/etc/smrsh/rt-mailgate: temp file is ‘/tmp/zMb7ekdrT3’
/etc/smrsh/rt-mailgate: connecting to

An Error Occurred

500 Can’t connect to
(SSL connect attempt failed error:1425F102:SSL
/etc/smrsh/rt-mailgate: undefined server error


You can try the line below as a workaround :

echo “This is a test” | /etc/smrsh/rt-mailgate –no-verify-ssl --queue support --action correspond --url --debug

Hi @bill_riner

check supported TLS versions of mailserver and rt-server. On either side there is an old SSL-lib installed, assumable. So the new side only supports modern, strong encryption while the other side offers only old, weak one.

Sometimes it is sufficient to disable old SSL/TLS versions or change the order in the offering.
