See example Sendnum on “Mailboxes” tab in “General Settings”. It contains a list and a plugin - user's mail processing program. When you send mail to sendnum@localhost, each message to be sent using the sendnum.lst list will be processed by the sendnum.exe (sendnum.dll) program. This program searches for %SENDNUM% sequence in the message body and replaces it with the first line from file sendnum.dat. After that, the first line of sendnum.dat file is deleted.

For example, this plugin is helpful when you need to send new serial numbers to your users. You have to create sendnum.lst containing addresses of your users and sendnum.dat containing the list of serial numbers. And the work that could take days will be done in a few minutes!

Sendnum.exe (sendnum.dll) is distributed with sources in C language, and you can easily modify it to expand capabilities of this plugin. We provide both .EXE and .DLL versions of this plugin. You can use any version, but .DLL version is faster.
