I could not find any way to see how you could add an IP address as a ‘white list’ for our Postini installation. Mails coming from our mailing list manager kept getting caught in the Postini spam interface (which is probably a whole other issue, which I will need to address later).

To get Postini to white list an IP address, you need to go into the Batch editing mode and issue this command:

addallowedip organization name,domain.com:10.0.0.0

See page 30 for ‘addallowedip’ syntax and more information.

For many people using hosted Exchange services, password saving problems could plague you. That is mainly because Outlook doesn’t like it if the Exchange server’s domain doesn’t match your domain.

Fortunately there is a way around this, because by the default way it is set up, you would have to enter your password every time you open up Outlook.

First step is to change the registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa

Change lmcompatibilitylevel to “2″

Here is the meanings of these numbers (source):

0 – Clients use LM and NTLM authentication, but they never use NTLMv2 session security. Domain controllers accept LM, NTLM, and NTLMv2 authentication.
1 – Clients use LM and NTLM authentication, and they use NTLMv2 session security if the server supports it. Domain controllers accept LM, NTLM, and NTLMv2 authentication.
2 – Clients use only NTLM authentication, and they use NTLMv2 session security if the server supports it. Domain controller accepts LM, NTLM, and NTLMv2 authentication.
3 – Clients use only NTLMv2 authentication, and they use NTLMv2 session security if the server supports it. Domain controllers accept LM, NTLM, and NTLMv2 authentication.
4 – Clients use only NTLMv2 authentication, and they use NTLMv2 session security if the server supports it. Domain controller refuses LM authentication responses, but it accepts NTLM and NTLMv2.
5 – Clients use only NTLMv2 authentication, and they use NTLMv2 session security if the server supports it. Domain controller refuses LM and NTLM authentication responses, but it accepts NTLMv2.

I’ve uploaded a registry file which will automatically make the change here.

You then need to access the advanced user dialog properties (see my previous article on this if you do not see a tab in Control Panel -> Users & Accounts dialog). Click “Manage Passwords” and then add a new entry. This entry should be the Exchange server’s real name – the name that pops up in your password prompt windows. In my example, in is MAILXXX.mail.lan.

Finally, make sure that the Exchange server’s local name, MAILXXX.mail.lan, is in your hosts file. For most Windows XP folks, this is C:\WINDOWS\system32\drivers\etc\hosts.

The format is:

69.x.x.x MAILXXX.mail.lan

where the real accessible IP address is the first part, and the real Exchange server name is the section part. This allows your PC to locate the “Real” Exchange server name over the internet, even though it is not a real exchange server’s hostname on the internet.

Lyris Listmanager is a nice mailing list management system. However, there are a few features that are missing out of the frontend that make it hard to get by your day-to-day office job. Fortunately, most of it is written with TCL routines which are not encoded, which makes for easy updates to this code.

Of course this is not supported by Lyris and if you have problems with it after making your changes, don’t expect them to support it. Make backup of your files – in Linux this is /usr/local/lm

For this example, I’m going to add the Full Name field to survey results. By default, it shows the email address but not the name of the responding user.

Step 1:

Backup!

cp -R /usr/local/lm /usr/local/lm.bak

Step 2:

Open the file which holds the routine for the “Survey Details” page. This is in /htdocs/reports/surveys/.tml

vi /usr/local/lm/htdocs/reports/surveys/.tml

Step 3:

Modify the code to add in FullName:

In the routine surveyreports::page_all_answers

Change
set sql "SELECT lyrSurveyResponse.WebDocID, lyrSurveyResponseAnswers.ResponseID as ResponseID, lyrSurveyQuestions.UserQuestionNumber, lyrSurveyResponse.ResponseTime, lyrSurveyResponse.MemberID, lyrSurveyResponse.RespondingIP, lyrSurveyResponse.MailingID, lyrSurveyQuestions.QuestionText, lyrSurveyAnswers.AnswerText, lyrSurveyResponseAnswers.FreeFormAnswer, [dbinfo::members_name].[dbinfo::members_emailaddr]

set sql "SELECT lyrSurveyResponse.WebDocID, lyrSurveyResponseAnswers.ResponseID as ResponseID, lyrSurveyQuestions.UserQuestionNumber, lyrSurveyResponse.ResponseTime, lyrSurveyResponse.MemberID, lyrSurveyResponse.RespondingIP, lyrSurveyResponse.MailingID, lyrSurveyQuestions.QuestionText, lyrSurveyAnswers.AnswerText, lyrSurveyResponseAnswers.FreeFormAnswer, [dbinfo::members_name].[dbinfo::members_emailaddr] as EmailAddr, members_.fullname_ as FullName


Change

array set heading_labels "AnswerText {Answer} ResponseTime {Date} QuestionText {Question} EmailAddr {Email Address}"

array set heading_labels "AnswerText {Answer} ResponseTime {Date} QuestionText {Question} FullName {Full Name} EmailAddr {Email Address}"

Change

array set column_width "ResponseTime 15 QuestionText 25 AnswerText 25 EmailAddr 25 Action_ 10"

array set column_width "ResponseTime 15 QuestionText 25 AnswerText 10 FullName 15 EmailAddr 25 Action_ 10"

Change

set sortable {QuestionText AnswerText ResponseTime EmailAddr RespondingIP}

set sortable {QuestionText AnswerText ResponseTime FullName EmailAddr RespondingIP}

Save this file and that is it! You will now have full names in your survey responses.

I used to use a Thunderbird addon to remove duplicate messages in Thunderbird. This is handy if your mail client becomes “de synced” from your mail server, whether it be an IMAP or POP3 connection. Also this can occur if you restore a backup or import mails and it creates duplicates.

However, after Thunderbird 2.0 was released, this old plugin was not compatible. Eyalroz re-released the plugin under GPL and with updates for Thunderbird 2.0. If you have a need to remove duplicate emails – this is the plugin you need! Get it:

Here are a few handy items for Postfix email server users:

1. If your system is acting as a spam / antivirus / relay server for secondary internal servers, and your destination mail server is down, postfix will queue your messages to resend at a later time. In order for postfix to instantly re-queue these messages you use:

postqueue -f

2. The mailq equivilant specific to postfix is

postqueue -p

3. If you want to delete specific messages in your queue, use an ncurses based open source software called pfqueue. It will give you a menu that shows mail currently queued, and allows you to delete specific emails.
