When the Drain0 filter is first installed and EIMS is first launched, the filter will create a preferences documents (entitled Drain0_Preferences.txt). This preferences document contains default settings for options in the Drain0 filter. The contents of the preferences document has full documentation for each setting. A complete description of every preference for the Drain0 filter is included in the Drain0 PDF manual.
Drain0 preferences allow the EIMS email administrator to control exactly what happens with emails containing stray linefeeds, stray carriage returns, and/or NULL bytes. They can be individually allow through or the offending bytes within the email can be substituted with different byte values. The preferences for Drain0 allow the email administrator to even specify what byte value to substitute into the email (space, ASCII 32, is the recommended value to substitute).
There is a Mac OS 9 version and a Mac OS X version of the Drain0 filter. These are entitled Drain0 and Drain0 X, respectively. Both builds of the Drain0 filter are available in the single download archive available from this Web site.
Please let us know what features and functionality you would like to see included in Drain0. The functionality available serves its purpose very well. Though we do have quite a few ideas for additional functionality to add, it is always helpful and much appreciated to have feedback from customers about what can be added to fulfill your needs.
