  I want to try to generate a certificate with Let's Encrypt, but I have a small problem. Port 80 cannot be used because it is used by a web server of the company. The MDaemon mail server has SMTP, POP3, IMAP and 81 and 443 ports open to the internet. 

  The documentation I read about MDaemon and Let's Encrypt uses port 80 which must be accessible from the Internet.  In our case, port 80 is redirected to a web server and not to the MDaemon server. 

  Can the ports 81 or 443 be used to obtain a Let's Encrypt certificate with MDaemon?.

  Can I get the certificate with Let's Encrypt on another server and import it into MDaemon?.

  Thanks in advance

  LetsEncrypt requires port 80 to complete HTTP challenges and the script we use only supports HTTP challenges.  There are third party tools you could use to request the certificate from LetsEncrypt.

  Yes, but unless you are using a wild card certificate from LetsEncrypt, the host name will be wrong on the certificate and lead to additional issues.
