I just configured a new server (homologation environment) with all security protocols enabled - HTTPS, DKIM, DMARC and TLS.
I would like your input if DMARC is worth using or not. I've read that there are a lot of problems with it. Do you guys use it?
I also would like to know if any of you have experience using Lets Encrrypt for TLS. I use Lets Encrypt with "Certify The Web" software to automate the renewing process. It works wonderfully for ISS.
So I used the same certificate to enable TLS. I followed these steps: Open MMC -> Export certificate issued by Lets Encrypt to some folder -> Configured Smartermail's bindings to use that certificate.
Eveything is working flawlessly, but my question is if I have to repeat this manual process every time the certificate is renewed.
If so, is there a way to automate this process?
