I am an older administrator who still uses Sendmail. I have about 20 years experience with it and I can solve any Sendmail problem I encounter. It was a nasty learning curve and I really don't want to do that again. Sendmail has had more than its share of problems over the years but now it seems pretty stable. It would be possible to switch to postfix but I don't see any reason to do that. Exchange is not even a possible option as far as I know... it doesn't run on Unix. Postfix is the only alternative I know... are there other MTA's available for Unix?
I have to say we Sendmail users probably should not chide Exchange on its security problems though.... people who live in glass houses shouldn't be throwing stones.

mail::milter::wrapper
Mail::Milter::Wrapper(3pm) User Contributed Perl Documentation Mail::Milter::Wrapper(3pm)
NAME
Mail::Milter::Wrapper - Perl extension for wrappering milter objects
SYNOPSIS
use Mail::Milter::Wrapper;
my $milter = ...;
my $wrapper = new Mail::Milter::Wrapper($milter, &foo);
use Sendmail::Milter;
...
Sendmail::Milter::register('foo', $wrapper, SMFI_CURR_ACTS);
DESCRIPTION
Mail::Milter::Wrapper wraps another milter, allowing for interception of the passed arguments and/or return code of the contained milter.
METHODS
new(MILTER, CODEREF[, CALLBACK ...])
Creates a Mail::Milter::Wrapper object.
MILTER is the milter to wrap, which may be a plain hash reference or an instance of a hashref object such as "Mail::Milter::Object".
CODEREF is the wrapper subroutine. CALLBACKs, if specified, are named callbacks which are needed by the wrapper, even if the contained
milter does not use them.
The wrapper subroutine will be called with the following arguments, in this order:
* reference to the wrapper
* name of callback
* subroutine reference to call into the wrapped milter
* arguments for the callback (>= 0)
This subroutine should ALWAYS pass the "close" callback through to the contained milter. Failure to do so may corrupt the contained
milter's state information and cause memory leaks.
As an example, a simple subroutine which just passes the callback through might be written as:
sub callback_wrapper {
shift; # don't need $this
my $cbname = shift;
my $callback_sub = shift;
&$callback_sub(@_);
}
