Hello,

Because the error is mentioning that the certificate doesn’t match the host this should point somehow that the certificate served by your Axigen server does not match for the hostname used for the secured connection.

Let’s say that you have obtained the certificate for mail.my-special-domain.tld and you have installed it in Axigen on a listener using 0.0.0.0:465.

Now, you should be able to double check the certificate using an online tool like:

Note: you should specify the server name like mail.my-special-domain.tld:465 otherwise it will check the certificate from the default port (which is the one for HTTPS = 443)

or you may also check it by yourself using openssl like:

$ openssl s_client -connect mail.my-special-domain.tld:465 -crlf
CONNECTED(00000003)
depth=2 O = Digital Signature Trust Co., CN = DST Root CA X3
verify return:1
depth=1 C = US, O = Let's Encrypt, CN = Let's Encrypt Authority X3
verify return:1
depth=0 CN = mail.my-special-domain.tld
verify return:1
