SYNOPSIS

AdvanceWrite = [true | false]

DESCRIPTION
The AdvanceWrite slow.conf configuration item determines if an illegal pipe is attempted. The check is made just after the SMTP HELO/EHLO command is receive and before acknowledging that command. If pending input is detected, the ${illegalpipe} macro is set to true, otherwise it is set to false. That macro is then passed to the Milter.

If this AdvanceWrite slow.conf configuration item is declared as true (or if it is omitted which defaults to true), the Milter will check to see if ${illegalpipe} is true, and if so, will set the pip event (as described in the standard event set).

If this AdvanceWrite slow.conf configuration item is false, this check is skipped.

For this check to happen two things must be set up first:

1. Your sendmail mc configuration file must have this line added to it:
   define(`confMILTER_MACROS_HELO', confMILTER_MACROS_HELO``, {illegalpipe}'')
2. You must install the correct patch must be installed to sendmail.
