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.
