MailBee Objects (ActiveX) v9.2 Released

Wednesday, 31 July 2019

Today we're announcing the new release of MailBee Objects, a set of COM/ActiveX components which implement SMTP, POP3, IMAP, SSL/TLS and S/MIME protocols.

In this release:

  • Better IPv6 support.
  • IMAP4 UIDPLUS extension support (IMAP4.UIDPlusResult property).
  • PFX support in SMIME.AddRecipientCert method.
  • Correct parsing of UTF-7-alike email addresses (with plus sign in them).
  • SMIME.CSP property now actually has effect (earlier it wasn't actually in use).
  • SHA-256 signing in now supported in S/MIME.
  • The default encryption method in S/MIME is now 3DES (seems to be supported by most mail clients around) instead of a weaker RC4.
  • S/MIME signatures now include full certificate chain.
  • More accurate error handling in S/MIME.
  • Documentation fixes.

Although the new version will keep working with your existing MBC900 key, you still need to have a valid maintenance contract in order to upgrade. In case if your maintenance contract has already expired, you'll need to renew it first. This can be done at (or just drop us a message if your key is not recognized).
