I got a letsencrypt certificate for my domain which should expire juli 12th.
When I check via command line it says this (running Letsencrypt 1.1.2.)
Which should be correct. When visithing https://www.mydomain.nl and checking the info, it's all oke with expiration date juli 12th.
However, when I chek my mail with outlook for that domain there is a security warning that the certificate date is not witin a valid date, it says:
Let's Encrypt authority X3
Valid from 12-02-2017 till 13-05-2018
It's European date, so it's valid from februari 12th till may 13th which is today.
This is strange, because also SSLLABS site gives the validation date of july 12th as expiration date also for mail, and giving it an A rating.
What can be causing this issue on this single domain?
My date/time on my pc is correct.
I'm running Outlook 2013 and Windows 10 v1803. I do not have issues with other ssl mail domains.
The server is running Centos 6.9, Letsencrypt 1.1.2, Exim 4.91 with spamblocker exim.conf v.4.5.9.
When I check via command line it says this (running Letsencrypt 1.1.2.)
Code:
Lets Encrypt domain: mydomain.nl
subjectAltName=DNS:mydomain.nl, DNS:mail.mydomain.nl, DNS:pop.mydomain.nl, DNS:smtp.mydomain.nl, DNS:www.mydomain.nl
