I must be braindead at the moment, but I have a problem with the Postfix SSL certificate. I set it up for the duration of 365 days and now it expired. I need to install a new one valid for 3650 days but can't get that to work using these commands: cd /etc/postfix/ssl/ openssl genrsa -des3 -rand /etc/hosts -out smtpd.key 1024 chmod 600 smtpd.key openssl req -new -key smtpd.key -out smtpd.csr openssl x509 -req -days 3650 -in smtpd.csr -signkey smtpd.key -out smtpd.crt openssl rsa -in smtpd.key -out smtpd.key.unencrypted mv -f smtpd.key.unencrypted smtpd.key openssl req -new -x509 -extensions v3_ca -keyout cakey.pem -out cacert.pem -days 3650 Even a /etc/init.d/postfix force-reload followed by /etc/init.d/postfix restart does not work, although all the files in the /etc/postfix/ssl have today's date stamp Any suggestions?
The files in /etc/postfix/ssl all have yesterday's timestamp so that should not be the issue. Doesn't anyone know what I am doing wrong?
I used the perfect server setup for 6.06 and 6.10 (happens on both servers), so I don't think it's chrooted (I didn't knowingly set it up that way anyway. I see the "certificate expired" on my mail client when retrieving IMAP mail. Here is main.cf: # See /usr/share/postfix/main.cf.dist for a commented, more complete version # Debian specific: Specifying a file name will cause the first # line of that file to be used as the name.

Then we are talking about the certificate of your IMAP server, not of Postfix. You can recreate them as follows (I'm citing from a PM I got a few weeks ago):
This did the trick, thanks! And I increased the "days" value in mkimapdcert and mkpop3dcert so that I will not have the same problem again next year
.pem from certificate signing authority Hi, I have the same problem, but I don't want to self-sign. I have a .csr file (certificate signing request), the .key file (private key), and a .crt file (certificate). How do I make a .pem from those files with openssl? Thanks, -Jon
