More Information

Removing LOGIN, NTLM, SCRAM-MD5 or CRAM-MD5 capabilities from the MailSite Services SMTPRA, POP3A and IMAP4A support the following authentication mechanisms: LOGIN NTLM SCRAM-MD5 CRAM-MD5

In some situations it may be necessary to remove these capabilities from the services. Outlook 2007 for example has some reported issues with NTLM when using a POP account.

To remove one or more of these options, simply locate the corresponding file in your MailSite directory and rename the file.

  • LOGIN - LoginAuth.dll
  • NTLM - MsspiAuth.dll
  • SCRAM-MD5 - Scram.dll
  • CRAM-MD5 - Cram.dll

For example to remove NTLM, rename the MsspiAuth.dll to MsspiAuth.old. The services will need to be restarted for this to take effect.

NOTE: This will remove a given capability from all the services.
