| Name | Description |
---|
 | AlwaysWriteContentTransferEncoding | Always write the content-transfer-encoding, even if it has default value of "7bit" |
 | DisableEncryptionKeyPreference | Do not include encryption key preference attribute in signed message attributes. |
 | DisableSMimeCapabilitiesAttribute | Do not include S/MIME options attribute in signed message attributes. |
 | DisableSinglePartHtmlWorkaround | Disable a workaround for broken mail clients such as Mac mail that don't correctly parse HTML-only messages.
By default, MailMessage class constructs a single-part multipart/alternative structure to solve this. This property
turns off this behavior. |
 | DoNotAddDateIfNoSubjectAndFrom | Do not automatically add a date header if 'date', 'subject' or 'from' headers are missing from a top-level or embedded message. |
 | DoNotParseMimeTree | Ignore the MIME tree and parse the message as a single-level entity. |
 | DoNotQuoteProblematicSequences | Disable encoding of leading 'F', '.' and '-' character in body parts using quoted-printable content transfer encoding.
These leading characters used to cause problems to legacy mail transfer agents, so quoted-printable-encoding them was used
as a workaround that doesn't cause any problems to properly-implemented mail agents. |
 | IgnoreInvalidTnefMessages | Ignore invalid TNEF (winmail.dat) attachments when parsing mail message. |
 | IgnoreUnparsableHeaders | Ignore unparsable headers when parsing mail message. |
 | IgnoreUnparsableSignatures | Ignore unparsable S/MIME signature entities when parsing mail message. |
 | LoadMsgProperties | Load Outlook MSG properties into custom MIME headers.
All these MIME headers start with X-Outlook- string. |
 | OnlyParseHeaders | Only parse message headers and ignore the body. |
 | PreferExplicitBody | Prefer BodyText and BodyHtml to be taken from its original .msg message fields.
Default is false, which means BodyText and BodyHtml are taken from BodyRtf if possible (if embedded). |
 | ProcessAllHeaders | Parse and reencode all headers, even when not needed or modified. |
 | RtfMode | The mode to process RTF in mails. |
 | SkipCertificateUsageCheck | Skip certificate usage check. |
 | SkipSenderCheck | Skip sender check. |
 | SkipTnefMessageProcessing | Skip TNEF (winmail.dat) attachment processing. If specified, the 'winmail.dat' attachment is not processed at all. |
