recent versions will not complain in this case (GET accepts NONE 
too)
i think in the VID case, the code is written that way so that it 
works correclty not only if face/action is a function, but also if 
it is a block (as it was in earlier versions of VID)

http: -> Circular forwarding is there any stable solution yet to 
avoid endless loops ? have tried to set different flaggs within the 
schemes object but can't  stop den endless loop. even read the messages-boards 
and found some hints but these doesn't work either. is there no flagg 
to set to prevend forwarding ? any hint are welcome... thanks

can you check port/locals/list? what do you get there?

hi gabriele, thx for reply. if I open the port, the loop instant 
apears. the only way to stop is to press escape... after this the 
port has no value.

Guest: you can try: port: make port! http://yoururlopen port  
 (after pressing esc you can access port/locals/list)
otherwise, just try with trace/net on. you'll get a lot of output 
but surely the answer will be there somehow.

Does anyone else find the fact that encloak/decloak CHANGES the 'data 
value passed to them confusing?  It sure has caused me quite a bit 
of headache!
Vincent

encloak/decloak : I think it's a good thing for security. You don't 
want having both encrypted and unencrypted data in memory. Modifying 
the data assure that the unencrypted string isn't available anymore 
(if you don't explicitly copy it.)
Ammon

Ah, I see.  That makes sense.

And it works the same way as replace or uppercase -- directly on 
the data.

rebol newby needs pop script to delete 1000 bounces from mailer daemon 
(was spam attacked) need to be able to delete emails based on subject 
or from to pattern. Thanks for any pointers or direction to sample 
script
Graham

the problem with the standard rebol pop protocol is that it doesn't 
allow you to download the headers only.
DideC has a script somewhere that allows you to examine your mail 
box and delete selected email.
I do too, but mine is part of a larger anti-spam package.

thanks Graham. this looks pretty neat . i may be able to use some 
of this code. i just need a simple script that connects to pop, loops 
through emails and checks each one for pattern in subject and deletes 
it if it matches. thanks again.
Graham

your're welcome guest
In most cases, where some spam has been bounced back to you as the 
account does not exist, the first line of the email says something 
like

Return-Path: <>

The <> is a special null email address to stop mail loops.


So, if you check all your email for this first line, then you should 
be able to delete all the automated bounces.

what is the correct way to handle vector arithmeitc? Or rather, is 
there an easy way to show vector arithmetic

eg.
2 * [2, 3, 4] .... results should be [6, 8, 10]

You could use Andrew Martin's map function to achieve this

do http://www.rebol.org/library/scripts-download/arguments.r; 
Needs

do http://www.rebol.org/library/scripts-download/map.r; Instantiate
map func [a][2 * a] [1 2 3 4 5 6] ; supply the function to map
>>[2 4 6 8 10 12]

trying to open a pop mailbox with nonstandard password with the following 
code:
REBOL []
 mailbox: open [
        scheme: 'pop
        user: "myname"
        pass: "%$100k"
        host: "mydomain.com"
    ]

foreach message mailbox [
    print message
    ask "Next? "
]
close mail
I get the following error when I do this: ** Script Error: foreach 
expected data argument of type: series
** Near: foreach message mailbox [
    print message
    ask "Next? "
]
close
this is from a simple example in the script library with the only 
modification being an open block instead of a single line open. Thanks 
for any insight.

that would happen if mailbox = none
try 

print type? mailbox before you use the foreach
MichaelAppelmans

[1218]
thanks Graham, I get " type has no value" does this mean that rebol 
is unable to open this pop account? I know my domain, user and pwd 
are correct
Graham
11-Jun-2005
[1219x2]
don't you need to specify the port id/
try setting 

trace/net on

before you open the port and see what happens
BrianH
11-Jun-2005
[1221]
No, it means that you used type instead of type? (with the question 
mark)
MichaelAppelmans
11-Jun-2005
[1222]
right  you are Brian, I had type ? not type? which returns port. 
so it is opening the mailbox but isn't mailbox a series?
Graham

I think some of the documentation on pop is incorrect as you have 
found.
MichaelAppelmans

aha. I think my understanding of using pop is flawed. i need some 
zzzzz's for now will play with this on the morrow. thanks for the 
help. gnight

complication is i have a password with special chars % and $ so i

that's not the problem
MichaelAppelmans
11-Jun-2005
[1228x2]
i think i figured out what the problem was, I had a pop block, with 
open mailbox: open [scheme: 'pop ...etc
i tried mailbox: read [scheme: 'pop and it's running but I expect 
to run out of heap space as I have 800 emails  ;)
Graham

; open mailbox

len: length? mailbox
bounces: copy []

for i 1 len 1 [
	email: import-email raw: pick mailbox i
	if email/reply-to = "<>" [
		append bounces i
		print [ "Bounce at" i ]
	]
]

; remove bounces

reverse bounces
foreach num bounces [
	mailbox: head mailbox
	mailbox: skip mailbox ( num - 1 )
	remove mailbox
]

close mailbox
untested ... :)
