Is it possible to have multiple IMAP-SSL certificates on one ISPConfig server? I have two ip addresses linked to it, and the SSL works great as far as a browser is concerned, but when I try connecting with a mail client, it thinks that it's the first IMAP-SSL instead of the newly created one with the second ip address. Much thanks
As far as i know, neither courier nor dovecot support the configuration on multiple ssl certs per server.
Hi, In the master.cf file I have Postfix setup as follows: <IP Address 1>:smtps inet n - - - - smtpd -o myhostname=<hostname> -o smtp_tls_security_level=may -o smtpd_tls_cert_file=<certificate filename> -o smtpd_tls_key_file=<key filename> -o smtpd_tls_CAfile=<bundle filename> -o smtp_bind_address=<IP Address 1> -o myorigin=<hostname> <IP Address 2>:smtps inet n - - - - smtpd -o myhostname=<hostname> -o smtp_tls_security_level=may -o smtpd_tls_cert_file=<certificate filename> -o smtpd_tls_key_file=<key filename> -o smtpd_tls_CAfile=<bundle filename> -o smtp_bind_address=<IP Address 2> -o myorigin=<hostname> I have Courier setup basically what you do is set the following directives. In imapd-ssl and pop3d-ssl I have the following set: TLS_CERTFILE=<path to CERT FILE> TLS_TRUSTCERTS=<path to bundle file> Then in the directory where these files located I have files that end in the IP address of host. If my filenames above are /etc/courier/darwin then I would have darwin.<ip address 1> and darwin.<ip address 2> More information about the formats of the files can be found in the configuration file. Hope this helps. The only issue that I have with postfix is that outbound mail always appears to come from one of the hostnames. I haven't figured out how to get it to appear from the hostname it was sent from. It hasn't been an issue for me so I haven't dug into it. (Any hints from anyone?).
Just an update. After updating my DNS to include AAAA I couldn't get any IPv6 clients to connect to Courier with SSL. I had to make a link to the certificate files with the IPv6 addresses at the end, courier couldn't find the files for the IPv6 addresses. So now I have this: TLS_CERTFILE=/etc/courier/darwin with these files in the /etc/courier directory darwin.<IPv4 address 1> and darwin.<IPv4 address 2> darwin.<IPv6 address 1> and darwin.<IPv6 address 2>
