Domino Server / Messaging router: Implement Sender Policy Framework / Sender Rewriting Scheme

Thu, 08 Nov 2007 17:54:46 +0000

Author: Jan Schulz

Idea: Implement SPF or better Sender Rewriting Scheme for forwarded Mail.

In certain circumstances, enabled SPF will reject forwared Mails from your domain: If you have webuser which get their Mail forwarded to a external adress, a certain percentage of Mailserver will not accept this mails anymore, as they don't come from the right server.

This happens for example with popular german freemailer: A GMX.de user sends a mail to a notes forwarding adresse which sends it back to a GMX.de user. If the latter has enabled this spam policy, the mail is rejected.

Comment: Jan,

Are you using Safari? If you are the text editor is still not working for Safari yet but will be soon. I can fix your post if you would like or you can edit it in Firefox or IE.

Comment: No, I'm using opera, but there is no RT Editor visible, just a plain text area :-(

It seems that I produced a save conflict, at least my repaired and edited entry is not visible, only the old broken version.

It would be great if you could fix that...

BTW: there are other problems with the design of the webside, for example the comment textarea is not directly under the last comment and the Introduction and the Top30 are below the comments, not to one side. This page is something like 5 Pages long. Is there a bug page?

Comment: Jan,

Currently we are targeting IE, Firefox and Safari. In my experience with my blog and OpenNTF we see very little Opera traffic if any. Would you be so kind enough to send me a few screenshots of what you are seeing? That would fantastic.

Comment: SPF is not a spam filter. It is an anti-spoofing technology. I think IBM is more likely to implement DomainKeys, however.

Comment: @8, depending on what you consider to be a "Spam Filter" I think a certain Mr. Linfoot { Link } would disagree with you. And I'll take his opinion on the matter any day.

Comment: @8 - SPF isn't a spam filter, like Rich says.

However, some form of anti-spoofing support in the Notes client would be nice. DKIM seems to have more mindshare and is in any case technically superior.

If someone wants to post an idea along the lines of "Implement DKIM", then I'll vote for that.

Domino Administrator / Admin Tools: Add console commands to create/delete/move DB

Sun, 09 Dec 2007 12:52:50 +0000

Author: Jan Schulz
Tags: admin console
Idea: I would like to have a command to create new, delete old Databases on the server (even in batch mode) and move DBs around.

I like the CL Commands (mainly because I don't have to go via the client -> fast over slow inet connections), but sometimes I have to add new Mail-In DBs or Teamroom and I would like to simple do a
XY add mail/something.nsf dwa7.ntf
and have a new DB without all the fuss going via client and in worst case pulling the ntf from the server, creating the DB and pushing the result back to the server.

Additionally, I would like to have a switch, which pulls the names from a textfile (like convert -f, but with two arguments).

I don't mind the work with the ACLs, but the problems with pullin and pushing 20MB of templates for each DB.

Deleting DBs has a different usecase: Doing one DB is simple with the admin client: on click and the DB is gone and I can even choose to delete them via adminp. I'm "cleaning up" right now and have big list of Mail-DBs, which have to go, but doing 30+DBs via adminclient, when I have the Names already in a textfile ist kind of annoying... Here I would like to see a command, which lets you specify a list of files (via textfile or as argument-list) and (optional) an adminp request is generated for Replicas (like the delete in adminclient) -> you can generate a list and just say: delete all DBs and replicas of that DBs).

Moving DBs around is also something I would like to see: currently (7.0.3 -> is there something new in 8.0?) I have to shut down the server and move the DB around on OS level. I would like to have domino command, which lets you move a DB from one place to another (like on unix: rename, move to a different dir). It would nice to have that as a adminp request as an option, which does that for all replicas as well (=same name and same replica). Usecase is retireing old DBs, which should be arround, but not anymore "in the way"...

If thats done, I would like to have the rest of the CL commands 'officially' supported: copy, new replica on differnt servers...

Domino Server / Security: Support Deny Access for IMAP

Tags: IMAP DenyAccess security
Idea: <div>When you put someone into a DenyAcess Group (or directly into a "Not Access Server"), this will prevent Notes and web access, but not IMAP and probably POP3.</div>

<div>We have several Webuser only and they can't be locked from the system without deleting their web-password :-(</div>

Comment: Wow, thanks! The 'enforce server access' was "no"... I should change this idea to better document that and default to "yes"

Comment: I just found this in the IBM Website:
---------------------------------------------
Question
Do any versions of Lotus Domino Support the Sender Policy Framework (SPF)?

Answer

The Sender Policy Framework (SPF) is essentially an extension to the Simple Mail Transfer Protocol (SMTP) and allows for a degree of SPAM protection.

Currently there are no plans in place for any versions (including Version 8) to support SPF.

IBM are actively working on other anti-spam initiatives.

Comment: The problem is more, that others have implmented SPF and when you have mailinglists or users with forwarded mails, mail send from external domains forwarded to external domains (somone@gmx.net -> mailinglist@mydomain.com -> someonelese@gmx.net) will be considered Spam (someoneelse@gmx.net will NOT receive the mail! -> Try it with tow GMX mails...). I don't want SPF implemented, I want to have the ability to rewrite the sender ("Sender Rewriting Scheme", the answer to this problem) so that a site with SPF will not consider it spam.

Maybe I should a new Idea with only this topic...

Domino Server / Messaging router: customise Mail Quota Warning

Sat, 23 Feb 2008 18:34:01 +0000

Author: Jan Schulz
Tags: Mail quota customization
Idea:

we have enforced strict mail quota rules for everybody (with the possibility to archive old mails and a 'archive attachments). Unfortunatelly some users don't get the mail quota warning message, so every few days we have to use our cluebat and tell them what to do after such messages and especially after their mail gets stuck in mail.box...

For that I would like to customise the mailquota warnings (subject and Message) to put there a bigger "do something now" message and more specific instruction what to do. And what happens when you don't do anything...
