Hi,
I tried searching the mailing list but didn't find anything specific.
I have a perlfilter setup and according to the courierfilter man page,
"The result code may be a multiline response, just like a regular SMTP reply."
How exactly do I provide a multiline response?
I tried outputting the e
ne?
I mean, if I spit out a 500 error, won't that disallow delivery for ALL
recipients? Is it possible to selectively allow some recipients and
disallow others?
Thanks again,
Ricardo

Thanks Sam.
So let me put it another way... other than internally generated courier
messages, and delivery status notifications, could there be an empty sender?
I'm trying to determine if in my mailfilter it is "safe" to accept
messages with empty sender, or if there are possibilities of malicio
ostmaster/mailer-daemon and any other valid
system-generated messages, including DSN and the like. But if I also
allow any message with an empty sender, then it might defeat the purpose
of the system.
I thought that the $SENDER variable was set to whatever the "MAIL FROM"
was set to du
er, is there a way for me to
tell whether this particular smtp session should or should not have an
empty sender? Again, the objective here is to allow empty sender messages
to pass through, but only if the empty sender seems "legitimate".

However, there is still a huge amount of bounces that are

Yes, the user field i

the message gets delivered to Maildir/new. Nothing else. No
forwarding is done, the delivery instruction which pipes to
sendmail is never executed.
So my problem is that I can't seem to figure out how to get
special delivery from within mysql
_CLAUSE anyway.
I'm not really using a "stock" setup in the sense that I do
need a custom query, because I'm checking against 2

users.

I'm not quite sure what you mean. The maildir field can be
