    Good morning,

    We're in the process of absorbing a cPanel server which we aquired when we took over another company. We are migrating the accounts to our own cPanel servers. The hitch is that there are users using the old server name in their e-mail client config and connecting with SSL. The SSL certificate is associated with a domain that will be retiring and will therefore become invalid in about a month.

    The question is, is there a way to identify which users are connecting using SSL + IMAP/POP3 by parsing logs?

    We'd like to contact just those connecting this way to provide them the new server name that they'll need to use after their account has been migrated.

    any ideas? We're not talking about many accounts. This server was pretty small and only has maybe 100 mail accounts so even manual methods would be acceptable.

    POP/IMAP access is logged to /var/log/maillog. With Dovecot, access via SSL/TLS will have "TLS" at the end of the line. With Courier-IMAP, you will see notations of "imapd-ssl" near the beginning of the line.

    Webmail access is logged in /usr/local/cpanel/logs/access_log, and you can see whether users are using port 2095 (non-SSL) or port 2096 (SSL).
