I would definately include polling of a POP box as a way to get mail into the system. Not everyone has a 24x7 internet connection with a fixed ip address and a dns entry, so for them polling a POP box would be a great way to handle things. Plus it is great for those people picky about security that don't let anything inward across the firewall. Ok, so you could set up fetchmail to poll the pop box and redeliver locally, but that is a lot of setup. And isn't there a ZScheduler that will schedule operations in the future? And there is that nice python pop client interface. > So: > - Within Exim, use the "pipe" transport to get email for a particular > host sent to a program on the standard input.

That way people can work with mail no matter how it was dumped into the system. An advantage is that adding a POP client would allow you to create a POP mail reader using zope also.

Product Downloads

Just a small suggestion:- Can you put a list of "Page Numbers" along with the next/prev 20 to make it easier to navigate into the middle of the pack ? Or a 'show all' link perhaps? At least you can binary search when you're looking for something rather than sequential search (and you don't know how many products you've got). Actually even Letter Ranges, Date Ranges and Author Ranges would be good instead of just Pages (there's even an example of doing that in the ZDTML guide so we know you know how to do it d8) -- Totally Holistic Enterprises Internet| P:+61 7 3870 0066 | Andrew Milton The Internet (Aust) Pty Ltd | F:+61 7 3870 4477 | ACN: 082 081 472 | M:+61 416 022 411 | Carpe Daemon PO Box 837 Indooroopilly QLD 4068 |akm(a)theinternet.com.au|

HappySession 0.1.0 released!
by Hung Jung Lu 05 Jun '00

05 Jun '00

Hi, I have been using RAM-based session management for a while, but never wrote a product for it. Since Graham Chiu has mentioned it again about making a real product, I have taken the time to make one, and called it HappySession. :) Well, in short, it uses cookie for session id, you specify a maximum session expiration time, and expired session data are automatically deleted. It's Zope-transaction-aware. I got a lot of help from Pavlos Christoforou (author of FSSession, a file-system-based session management product.) Thanks a lot, Pavlos! Give it a try. Let me know whether there is any problem. It's easy to use, or at least that's what I have intended. :) It's my very first product, so if there are any bad things that I have done, please let me know. Here is the URL: http://www.zope.org/Members/hungjunglu/Products regards, Hung Jung ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com

How to ZCatalog DTML documents and/or HTML files automatically?
by jan＠haul.de 05 Jun '00

05 Jun '00

Hello, this is probably a stupid question, But I'm damned if I can find a solution :-( We have an internal site to store technical documents (in HTML or as DTML documents). We are using ZCatalog to provide an index for it. Now, we want to have some mechanism that updates the index every night (including pages added during the day). On this list, I have read that the obvious solution, ZScheduler, "does not work". I take it "does not work reliably for all conceivable uses". Does this mean it is likely to work for what I have in mind? Are there any other ways to achieve it? I am running this on Unix (Solaris 7, in fact). Confused, Jan

I'm trying to install the PoPy Python module on my Yellowdog Linux system (a redhat clone for PowerPC hardware). I'm sure it's a simple task, but I don't know how to do it. Any suggestions or tips? Thanks in advance. Building highways to reduce traffic is like loosening your belt to reduce obesity

is WebDAV a security hole?
by Jacob Lundqvist 04 Jun '00

04 Jun '00

Been playing around with WebDAV from IE5 connecting to a RedHat 6.1 +Zope 2.1.6 And it seems that quite a bit of the stuff that propably shouldn't be visible can be seen, for example acl_users Without being logged in I can start a download of it, eventually IE5 fails, but I get this uncomfortable feeling that this is more due to IE5 not handling this document type than anything else... If I used some other WebDAV client, could I then download acl_users, and if so, would this expose usernames/passwords? I haven't fiddled with the Security Tab for acl_users, so it should be default permissions. Are they bad and what should they be changed to? --- Mail: Jaclu(a)galdrion.com Phone: +46-708-555 456 Am I there? http://maja.luba.se/jacob/jacob.jpg

permissions for the folder at /
by Paolo Pumilia 04 Jun '00

04 Jun '00

Hi all zopers, I've been playing around with zope 2.1.6 (debian distrib) for a few days. Today accessing zope main page was weird: no password is required any more to access the root folder management page. Permissions are however restricted, so no dtml methods and no new directories can be created in the main folder. Can anybody try to explain what ha s happened? How to change permissions for the folder at root? thank you for your help Pol ______________________________________________________________________ Do You Yahoo!?

Hi Mark, In your last message about ZClass ( http://lists.zope.org/pipermail/zope/2000-June/026685.html ) your wrote : > thanks! the cool thing about our tutorials is that > all our customers get free updates for one year --- > giving us bees a chance to correct any errors as well as > document any (in this case ZClass) new features/changes. So, when will come the next update of ZClass manual ? Will you add a part for non beginner, and if yes what one could expect ? FR
