Applies to: eXpurgate On-Premise, configuration, TLS, certificate, chain Modified on: 08/09/2016 Description:eXpurgate allows to receive and deliver emails via TLS-encrypted connections. In addition to encrypting the communication it is possible to verify the authenticity of the respective communication partner. A private key and a certificate in accordance with X.509 are required for this. eXpurgate supports self-signed certificates and certificates from a Certificate Authority. Certificates and keys have to be Base64 encoded test files. Common filename extensions are PEM, CER and CRT. The certificate file used in eXpurgate's configuration has to have the following structure: -----BEGIN CERTIFICATE----- Please note: eXpurgate does not support binary encoded DER. The path to the certificate file has to be added to the <Tls> section in eXpurgate's configuration (default: /etc/expurgate/expurgate.conf):
In MS Windows double backslashes have to be used:
The parameters TrustedCertificate and TrustedCertificateDirectory are to be used to validate the certificates of other clients that might connect to eXpurgate.
