Renew pop3 SSL

[Dave W]

Howdy,

Plesk 12.5, postfix MTA.

Ive been playing around with gmail connecting to my VPS for mail, however gmail wont accept an expired SSL cert for POP3 on port 995 [Server returned error: "SSL error: certificate has expired"]

Is there a kb that shows how to renew the SSL certs for pop3s and imaps aswell?

OK, so to renew the SSLs for postfix smtp and pop3s and imaps:

Backup old plesk ssl cert:
cd /usr/local/psa/admin/conf/
mv httpsd.pem{,.old}

Create new cert of same name:
openssl req -new -nodes -x509 -out httpsd.pem -newkey rsa:2048 -keyout httpsd.pem -days 3650

Set Permission:
chmod 400 httpsd.pem

Backup old smtp, imap and pop certs:
mv /etc/postfix/postfix_default.pem /etc/postfix/postfix_default.old
mv /usr/share/imapd.pem /usr/share/imapd.old
mv /usr/share/pop3d.pem /usr/share/pop3d.old

Copy cert to imapd.pem pop3d.pem and postfix_default.pem
cp -p httpsd.pem /usr/share/imapd.pem
cp -p httpsd.pem /usr/share/pop3d.pem
cp -p httpsd.pem /etc/postfix/postfix_default.pem

So now at least the SSLs arent out of date, however now gmail complains that the SSLs are self-signed.
