Majordomo List Owner Guide

Special Features for List Subscribers

Changing Addresses

If someone wants to change her address from jane@example.com to ruth@example.net on all mailing lists, without changing her password or any of her settings, there are two ways to do it.

ruth@example.net can send the following command to majordomo:
```
changeaddr jane@example.com
```

Anyone can send the following two commands to majordomo:

default user ruth@example.net
changeaddr jane@example.com

In either case, both jane and ruth will need to confirm the change, with two exceptions. If the password for jane@example.com is used, only ruth@example.net will need to confirm. If the site administrator does this using the master password, neither address will need to confirm the change.

Digests

Unlike other list servers, majordomo allows list owners to define any number of digests, and each digest can be delivered in one of three formats, text, index, or mime.

As an illustration, consider a list called ecofem that has three weekly digests defined, monday, midweek, and weekend. This would give a subscriber 3 x 3 = 9 choices of digest. If someone wanted to receive the midweek digest in text format, the majordomo command to accomplish this would be

set ecofem digest-midweek-text

The are no digests configured by default, and the names and distribution times of each digest are left to the list owners' imagination. To see the digests that are supported by a particular list, use the lists command, for example:

lists-full ecofem

Subscriber Flags

When a subscriber changes the status of her account with the set command, the acknowledgement she receives from majordomo will show the current settings. These settings also appear whenever someone uses the show command. There are ten settings that indicate the following features. If the feature is enabled, the name will appear in the list of settings. Use the appropriate list name in place of LIST in the examples that follow.

EliminateCC will keep you from receiving duplicate copies of a message that is sent both to the list address and to your personal address directly. Enable/disable this feature with
```
set LIST eliminatecc
set LIST noeliminatecc
```
HideAll will keep your address or all of your information from appearing in the subscriber list when someone uses the who command. To hide all information, use
```
set LIST hideall
```
To hide only your address (this will be indicated by a small "h" flag) use
```
set LIST hideaddress
```
And turn this feature off with
```
set LIST nohide
```
Prefix causes the Subject: lines in your messages to include a prefix, if a prefix has been configured by the list owners. Enable/disable this feature with
```
set LIST prefix
set LIST noprefix
```
ReplyTo makes any Reply-To: headers added by majordomo be included in each message that you receive from the list. In some cases, mailing lists will be configured so that replies go to the list instead of the original sender. Many of us have sent personal mail to a mailing list by mistake, once or twice. Using "noreplyto" makes this less likely. Enable/disable this feature with
```
set LIST replyto
set LIST noreplyto
```
SelfCopy controls whether or not subscribers will receive copies of messages that they send to the list. Enable/disable this feature with
```
set LIST selfcopy
set LIST noselfcopy
```
RewriteFrom determines whether or not the From: line will be rewritten when you send a message to the list. It is possible to register with Majordomo using not just an address, but comments about yourself as well. Majordomo will add these comments to the From: headers of your messages, if you wish. Enable/disable this feature with
```
set LIST rewritefrom
set LIST norewritefrom
```
There are four setting for acknowledgements, ackdeny, ackpost, ackreject, and ackstall. Each setting may be changed individually, or they may all be turned on ("ackall") or off ("noack") with one command.
AckDeny determines whether or not a warning message is sent to you when a posted message is denied by a mailing list's settings. Enable/disable this feature with
```
set LIST ackdeny
set LIST noackdeny
```
AckPost will cause a message to be sent to you each time a posted message has started to be delivered to the subscribers of the mailing list. Enable/disable this feature with
```
set LIST ackpost
set LIST noackpost
```
AckReject will cause a message to be sent to you each time any request (posted message or majordomo command) is rejected by one of the moderators of a mailing list. Enable/disable this feature with
```
set LIST ackreject
set LIST noackreject
```
AckStall will cause a notice to be sent to you when a posted message is held, awaiting approval from one of the list's moderators. The reasons the message is held may be indicated in the notice. Enable/disable this feature with
```
set LIST ackstall
set LIST noackstall
```

Scheduling Vacations

If a subscriber plans to be away from the list for a known amount of time, it is possible to leave the list for a predetermined amount of time, using the nomail option. If I wanted to stop receiving mail from the ecofem list for 10 days, I would use the command

set ecofem nomail-10d

At the end of the 10 days, majordomo will automatically reactivate my subscription, and I will start receiving messages from the list again. If I returned from vacation early, the following command would cause my subscription to be reactivated immediately:

set ecofem mail
