esniff is a tool designed to extract email addresses from text files of any format (or no format at all).
esniff writes the extracted list to a text file, ready for use with mail-merging tools.
esniff removes duplicates and alphabetacises the outbound address listing.
 
- Requires Windows 95 or higher.
- This program is LICENSED SOFTWARE and may not be copied or distributed without prior written permission of the author.
- Please see the license agreement included with the software for the complete terms and conditions of use of the software.
 
- run the self-extracting archive
 
- Using a text editor such as Notepad, edit ESNIFF.INI (in the same directory as the program file) to suit your configuration. A summary of settings is below:
| setting | meaning | example |
| source | is a file containing email addresses to extract | D:\EMAIL.TXT |
| target | is a file to write the extracted addresses to | D:\INBOUND.TXT |
| logfile | is a file which contains a record of what esniff does | D:\ESNIFF.LOG |
Comments may be included in the INI file by prepending them with a semicolon, as such:
;any line starting with a semicolon is treated as a comment and is ignored
;target=[this setting is disabled]
 
- Type ESNIFF from the command line to execute the program.
esniff will attempt to extract email addresses from the source file, and write them to the target file, without prompting for additional instructions. Once the extraction is complete, the program will exit.
If the target file exists, it will be backed up, then appended to; if a backup already exists, it will be deleted.
Note: A maximum of 2000 addresses are supported in a single source file.
 
- ensiff will not use Long File Names
