Drain0 v1.0.1 Released by Deep Sky Technologies, Inc.

EIMS Filter for Cleansing Email of Invalid Byte Values

Vero Beach, FL - Tuesday, September 20th, 2005: Deep Sky Technologies, Inc., today announced the release of Drain0 v1.0.1 for Mac OS 9 and Mac OS X. Drain0 is a filter for Eudora Internet Mail Server (EIMS and EIMS X) to cleanse email of invalid byte values, correcting many problems that exist with different mail user applications (MUAs) that fail with, for instance, NULL bytes.

Drain0 allows for substituion of byte values to be inserted into emails for NULL bytes, stray linefeeds, and stray carriage returns. By default, these byte values are replaced by spaces, though within the preferences of Drain0 individual functionality for these different byte values can be enabled and disabled, and the substitution byte values can be specified distinctly for each.

No longer will users retrieving email from an EIMS server have "stuck" email when Drain0 is in use.

This small update to Drain0 adds support for the replacement of stray carriage returns in emails within EIMS. Also included with this update are EIMS Error Log entries whenever Drain0 does perform any substitutions.

Features in Drain0

The Drain0 filter has the following features and options that can be easily customized for individual needs:

  • Discrete management of stray linefeeds, stray carriage returns and NULL bytes;
  • Settable substitution values for each content scanned problem byte;
  • Exceptions for BINARYMIME formatted SMTP transactions;
  • Fasting possible direct memory operations for rewriting email content;
  • EIMS Error Log entries made whenever substitutions are made;
  • Support for standard and custom DNS (IP) Exclusions document;
  • Does not interrupt operation of EIMS;
  • Compatibility with Mac OS 9 and Mac OS X;
  • Compatibility with EIMS and EIMS X;
  • Email notification of error conditions.

All of the functionality available within the Drain0 filter is customizable to match the exact needs of the EIMS administrator.
