    • BounceMail component (parser of bounced e-mails).
    • Verification of e-mail addresses in bulk mode.
    • Mail merge over database.
  • UWP edition can now be used in Release builds.
  • Multiple SMTP enhancements:
    • Empty MAIL FROM is now allowed for SMTP.
    • No extra CRLF in the end of DATA transmission in SMTP.
    • MAIL FROM now includes SIZE if the SMTP server limits the size of messages being submitted.
    • Short path of SMTP authentication (required by Microsoft SMTP servers).
  • Protected constructors for exception classes (required to make exception serialization work properly).


  • Miscellaneous bug fixes and improvements (mostly, to Microsoft Outlook .MSG parser and builder).


MailBee.NET SMTP enables .NET applications to compose, mail merge, send mail to SMTP server (including SSL/TLS like Gmail), submit to IIS queue, or directly send via DNS MX lookup.
