.IX Header "DESCRIPTION"
Mail::Milter::Wrapper::DeferToRCPT is a convenience milter wrapper which
defers any error return during the \*(L"connect\*(R", \*(L"helo\*(R", and/or \*(L"envfrom\*(R"
callbacks to the \*(L"envrcpt\*(R" callback.
.PP
Many broken client mailers exist in the real world and will do such things
as instantaneously reconnect when receiving an error at the \s-1MAIL FROM:\s0
stage.  This wrapper ensures that errors are never propagated back to the
\&\s-1MTA\s0 until at least the \s-1RCPT TO:\s0 phase.
.PP
Errors in \*(L"connect\*(R" and \*(L"helo\*(R" will apply to the entire \s-1SMTP\s0 transaction.  
Errors in \*(L"envfrom\*(R" will only apply to that particular message.
.PP
This wrapper can also be used to enhance logging.  Though the contained
milter may wish to reject a mail in progress, it may be useful for logging
purposes to capture the \s-1HELO\s0 string, sender, and recipient addresses of
each attempted mail.
