ADR creates the separate copy of letter for each address in mailing list, so a large disk space may be required for sending a big letter by a large mailing list. AdrDelay helps to solve this problem.

Plugin reads MaxOutboxMessages parameter (it’s 500 by default) from AdrDelay.INI file. When plugin run for processing the next message sent by mailing list, it check the number of messages in directory with outgoing mail and wait while this number become less than MaxOutboxMessages value. So, the creation messages by list is interrupted temporarily after creation the given number of messages and is resumed only after sending the part of messages. Also it’s recommended to use “Delete message after sending” setting for saving disk space.

AdrDelay.exe (AdrDelay.dll) is distributed with sources in C language. We provide both .EXE and .DLL versions of this plugin. You can use any version, but .DLL version is faster.
