Namespace: MailBee
Assembly: MailBee.NET (in MailBee.NET.dll) Version: 12.4 build 677 for .NET 4.5
public const int BadMessageData

Field Value

Type: Int32
The most common reasons of this error:
  • The message is too large
  • The server thinks the message contains SPAM or virus
  • The message contains invalid headers
  • The message sender and/or recipients specified in the message header differ from the actual sender/recipients, and the server does not allow this (the developer may consider adding Resent-From: header to the message specifying the actual sender e-mail address as the header value)
