Hello, If I would like to use the following for mail server: pop.example.com smtp.example.com How to implement? Do I add only A records for the pop.example.com and smtp.example.com? Or Do I need to add subdomain only? Or both!? Thanks in advance,
Great that works like a charm. However if I use pop.example.com , now it gives me the warning for ssl. Previous to using pop or smtp.example.com, I have followed the below instructions to get rid of the warning but now I am not sure what to do? cheers,
You have to either user a name that is in the certificate (looks like 'smtp.ic4.eu' for postifx and 'imap.ic4.eu' for imap/pop) or request a certificate with multiple names in it (eg. if you requested a certificate with both pop.ic4.eu and imap.ic4.eu, you could use either name without warnings).
Well, sorry I updated the quote in the message three as I took it for the different post. I understood from Till at the following post that it could be done by a symlink. how?! https://www.howtoforge.com/communit...g-3-with-letsencrypt.74738/page-2#post-356648 Thanks
The certificate locations you put above in /etc/letsencrypt/live/*/ are symlinks already, to the current set of files (under /etc/letsencrypt/archive/*/). You can use the default location under /etc/postfix/ if you prefer, eg. see https://www.howtoforge.com/community/threads/letsencrypt-on-mail-server.73695/
