Mailman requires an exact match between the way the message sender's email address appears in the list as an unmoderated member or in the approved sender list to allow immediate distribution of a message sent to the list address.

Exact matches can be difficult here at U.Va. where people can have multiple versions of their email address as well as one or more email alias addresses.

Sometimes, depending on the email client that is being used to send the message, the person sending the message will have little or no control over how the sender's email address on the message will appear. Fortunately, Mailman allows the use of "regular expressions" that simplify the addition to the approved senders list of the various email addresses a person here at U.Va. might have. Each alias address for an individual must be added separately to the approved senders list. Email addresses from outside U.Va. can be added as they appear or with a regular expression to allow for all permutations of addresses at that site.

• Adding U.Va. approved senders
• Adding non-U.Va. approved senders
• Adding U.Va. Email Alias Addresses

Adding U.Va. approved senders

To use a regular expression to add to the approved senders list all permutations of a U.Va. email address (example: mst3k), you will:

1. Access the list administration website for your mailing list.
2. Click Privacy options.
3. Click Sender filters.
4. Scroll down to find List of non-member addresses whose postings should be automatically accepted.
5. Click in the box and add a regular expression similar to the following for each U.Va. person that you want to be able to send messages to the list without review even if their email address is an unmoderated list member:
   
   
   ^U.Va._Computing_ID@.*virginia.edu

   Description of the above: Begin the line with a caret (^), followed by the U.Va. Computing ID (example: mst3k), an "at" symbol (@), a period (.), an asterisk (*) and end with "virginia.edu".

   Example: ^mst3k@.*virginia.edu

   This regular expression tells Mailman that for the specified ID, any email address that ends with virginia.edu is a match.

6. Click the Submit Your Changes button at the bottom of the page.
7. If you have completed your list administration work, remember to click the Logout link and close your browser.

Adding non-U.Va. approved senders

As other sites on the Internet sometimes use varying email addresses for people in their domain, if you have a non-U.Va. approved sender/list member, you should add to the approved senders list a regular expression that will allow Mailman to recognize all permutations of their email addresses.

1. Access the list administration website for your mailing list.
2. Click Privacy options.
3. Click Sender filters.
4. Scroll down to find: List of non-member addresses whose postings should be automatically accepted.
5. Click in the box and add a regular expression similar to the following for each non-U.Va. person that you want to be able to send messages to the list without review even if their email address is an unmoderated list member:
   
   
   ^emailid@.*somewhere.net

   Description of the above: Begin the line with a caret (^), followed by the non-U.Va. email ID (example: mstheatre), an "at" symbol (@), a period (.), an asterisk (*) and end with the person's domain information, which is typically the last two parts of their email address.

   Example:
   For the address: mstheatre@comp.name.somplace.net
   Use: ^mstheatre@.*someplace.net
   
   
6. Click the Submit Your Changes button at the bottom of the page.
7. If you have completed your list administration work, remember to click the Logout link and close your browser.

Adding U.Va. email alias addresses

Each alias address for an individual must be entered separately with no special formatting.

1. Access the list administration website for your mailing list.
2. Click Privacy options.
3. Click Sender filters.
4. Scroll down to find: List of non-member addresses whose postings should be automatically accepted.
5. Click in the box and add unchanged the email alias address for each U.Va. email alias address (example: mystery@virginia.edu), that you want to be able to send messages to the list without review, even if the person's email address is an unmoderated list member:
   
   
   email_alias_address@virginia.edu

   Description of the above: Enter the person's U.Va. email alias address followed by an "at" symbol (@) followed by "virginia.edu."

   Example: for the alias: mystery@virginia.edu, enter: mystery@virginia.edu
   
   
6. Click the Submit Your Changes button at the bottom of the page.
7. If you have completed your list administration work, remember to click the Logout link and close your browser.

Allow messages from any email address ending in virginia.edu

To configure your list so that messages from list members and any sender whose email address ends in "virginia.edu" are the only messages distributed immediately to the list members, do the following.

Moderate your list and add the non-U.Va. list members to the approved senders list. Next add a regular expression to accept messages from any email address that ends with "virginia.edu."

1. Access the list administration website for your mailing list.
2. Click Privacy options.
3. Click Sender filters.
4. Scroll down to find: List of non-member addresses whose postings should be automatically accepted.
5. Click in the box and put the following regular expression into it:
   
   ^.*@.*virginia.edu
   

   What you type must match exactly what is shown.

   Description of the above: Begin the line with a caret (^), followed by a period (.), an asterisk (*), an "at" symbol (@), a period (.), an asterisk (*) and end with "virginia.edu".

   This regular expression tells Mailman that any ID in the virginia.edu domain is an approved sender for the list.

6. Click the Submit Your Changes button at the bottom of the page.
