Unable to secure SMTP connections.

You have received commercial certificates which you want to apply also for SMG appliance.

Under Modules Management -> Interfaces -> SMTP Interface Manager -> your SMTP profile -> SSL you have enabled SSL/TLS settings and filled in the certificate, the key and also a passphrase.

However, this does not seem to work and in the SMTP logs of your SMG you see complaints over starting SSL/TLS conversations with other hosts that support secured SMTP.

There is currently a bug on SMG site affecting cases where certificates were delivered with the passphrase string.

A current workaround is to remove the passphrase from certificates.

You can use openssl tool from Linux, i.e. directky from SMG appliance.

Run this command:

openssl rsa -in [original.key] -out [new.key]

Encrypted headers look like this:

openssl rsa -in [original.key] -out [new.key]

-----BEGIN RSA PRIVATE KEY-----
Proc-Type: 4,ENCRYPTED DEK-Info: DES-EDE3-CBC,

6BD407785DD187EF...
-----END RSA PRIVATE KEY-----

Unencrypted headers look like this:

-----BEGIN RSA PRIVATE KEY-----
6BD407785DD187EF...
-----END RSA PRIVATE KEY-----
