| ANTI-SPAM AND LIST SECURITY |
| |
Spam is a big problem in the world of
email and many of us are bombarded with it on a daily basis.
At JISCMail we take spam very seriously, and together
with list owners, we can provide very effective screening
against it:
|
| |
 |
The first level of protection comes
into effect before email even reaches JISCMail. A separate
server checks senders addresses against black-lists
maintained by reputable anti-spam organisations. |
|
The second level of protection is LISTSERV®,
the mailing list software that powers JISCMail. While
the exact workings of LISTSERV's anti-spam mechanisms
are not published, to avoid being caught out by them,
you
should
not cross-post.
ie: do not post the same message
to more than one list at the same time. If you need to
post to more than one list, contact the Helpline for
details of what options are available to you. |
|
The third level of protection is the
list configuration, which is under the control of the list owner.
Various settings can affect how secure
a list and its subscribers are from spam. See List
Security below for details. |
|

of spam, please contact the Helpline. |

| LIST SECURITY |
| |
| As a list owner, you can change the configuration
of your list at any time and entirely at your discretion.
However, some of these changes can have security implications for
the list
and its
subscribers which you should be aware of. The main points to note are: |
| |
| Send= |
A 'Public' list allows anyone to post, regardless of whether they are a member or not. However, by default, the 'Send' option will be set as 'Send= Public,Confirm,Non-Member' which forces non-members to confirm that their address is valid and avoids spamming attempts from automated systems. |
| Review= |
This is the option that determines who may view subscriber's email address details. JISCMail
recommends that this is set to 'Private' so that only subscribers to the list can access details of other subscribers. Alternatively, it may be set to 'Owner/s' if details should be kept more confidential. |
| Subscriptionr= |
JISCMail recommends a minimum setting
of 'Open,Confirm' for this option. This means that when someone subscribes
to a list, Listserv sends out an 'OK confirmation' email
that they must respond to before their subscription is
accepted. This avoids the problem of automated
spamming mechanisms joining the list. For greater security, you can choose the have all subscription requests sent to an owner for approval by setting this to 'By_Owner,Confirm'. Some lists may also specify 'Closed' if they do not wish to accept new members. |
| Notebook= |
This is the line that controls who may access your list archives. When set to 'Public' , anyone, regardless of whether they are subscribed to the list
or not, can view the message archives and the email addresses
contained there. If it is set to 'Private' , only the list members will be able to access the archives. |
| Confidential= |
When this is set to 'Yes', the list will not appear on the JISCMail A-Z or Category Pages and will therefore not be visible to potential new members. |
