Signs the current e-mail message with DKIM and classic DomainKeys signatures.

Parameters

isWebApp

Must be true for ASP.NET applications, false otherwise.

headersToSign

The array of the names of the headers to be included in the signature, or a null reference (Nothing in Visual Basic) if all the message headers should be included in the signature.

privateKeyStr

The contents or the filename of the DomainKeys/DKIM private key.

isFilename

If true, privateKeyStr denotes the private key filename; otherwise, the contents.

selector

The prefix of the sub-domain serving DomainKeys/DKIM for the sender domain.

dkTypes

Specifies which signatures to create (classic DK, newer DKIM, or both).

Remarks

If you need more advanced level of DomainKeys/DKIM signing or additional information on private keys, certificates and so on, refer to DomainKeys class.

Moreover, in ideal case it should be your your mail server's job to sign outgoing e-mails with DomainKeys/DKIM signatures. Use MailBee only if you cannot enable this feature on your mail server.

Exceptions

Example

This sample composes a simple e-mail, signs it with DomainKeys and DKIM signatures and sends it out. We assume the private certificate is in "C:\Temp\rsa512.private" file and the domain selector is "dk".
