TLS SSL Support
Mailtraq Professional 2.14 and above, provides SSL/TLS support for SMTPS, POP3S, IMAPS and HTTPS webmail.
The implementations support both implicit and explicit security, meaning that you can either require a completely encrypted session or offer the client the option to upgrade to a secure session within the transaction.
Mailtraq provides a certificate issuing system producing PKCS#10 requests compatible with all the major certificate authorities.
See Certificate Manager for information on the creation of Secure Certificates and Mailtraq's high security options for HIPAA and PCI compliance?.
Port 25 TLS Support
May 5, 2020: A bug has been reported on TLS outbound connections. Status: unresolved
To provide TLS support to standard SMTP transactions on Port 25, set the SMTP Service SSL-tab to Explicit mode, and select the Certificate you created or installed earlier.
Adding TLS SSL Services
The SSL-tab will be found on the individual Services Properties dialog, accessed from the Mailtraq Console: Options | Services
Note that the ports used by SSL/TLS services are different from the default service ports.
You use the Service Manager to add these additional TLS services and configure them. You will also need to configure your router/network/firewall routing accordingly.
SMTPS - secure on 465 (plain text 25)
HTTPS - secure on 443 (plain text 80) See: Secure webmail
IMAPS - secure on 993 (plain text 143)
POP3S - secure on 995 (plain text 110)
You will also need to specify that your email clients are configured to use SSL connections on the specified ports. There are numerous third-party guides to setting up Outlook, Thunderbird and other clients.
How to test a TLS connection - a worked example...
If you have difficulty connecting your client, try switching between Explicit and Implicit. Outlook Express, for example, can use Explicit Mode under Windows XP but uses Implicit Mode under Windows 2003
