I found that /usr/lib/courier/imapd.pem was softlink to /etc/courier/imapd.pem.
(same for pop3d.pem)
I tried the following:
rm both imapd.pem files, then run 'mkimapdcert'. Now error message. imapd.pem was generated in /usr/lib/courier/. Then I mv the pem file to /etc/courier/ and re-create the softlink.
Are these steps OK.
I am setting up this mail server for internal LAN use (not open to the internet). Is setting up courier SSL server of any use?
Whenever I connect to the mail server using an email client (outlook, thunderbird), a message pop up saying that the certificate is not from a trusted source. How can I let the email client know that the certificate can be trusted and avoid the pop up message?
Thanks in advance.
