Everything is working fine but I keep getting this message every day. Since I'm kind of anal, it annoys me . It's a PEM file several years old while everything else is up to date. Is this just a leftover file that can be deleted or no? (See screenshot.) Thanks in advance.
OK, I thought all was well and deleted the file. However, now my TLS on my SMTP server stopped working and I can't turn it back on. The box is greyed out. Any ideas how to fix this?
Unfortunately is already is off, the trouble is turning it back on. All my certs are valid on all my domains. Just apparently not for SMTP but it was fine for years.
If you are genuinely running IIS6 (Windows Server 2003) you need to forget about getting this to work and migrate your services to a new operating system. Microsoft support for that OS ended 8 years ago, as you would expect for an OS that's more than 20 years old.
It's Windows Server 2019, (IIS 10) but it still has part of IIS 6 just for the SMTP server. They all do as far as I know, I believe it's packaged with it. I've been on 2012 and 2019 and they both have it.
