Hello guys,
I´m currently using Sophos XG Email protection in MTA mode.
I uploaded my exchange certificate into Sophos and using this certificate in SMTP TLS Configuration.
When I try to send and email I can see this error in logs
INF Nov 17 18:38:43 [0xc0000002]: Server certificate error 'unable to get local issuer certificate'
Certificate is generated by Lets Encrypt installed on exchange server and valid as well.
Any ideas how to fix this?
Thank you very much for any help!
Regards
Jiri
