Subscription Option Settings
For a more comprehensive reference on all LISTSERV option settings
(including how to set options by mail), please see the section on
How To Set
Your Subscription Options in the
General User's Guide
With a "regular" subscription, you receive individual postings
immediately, as they are processed by LISTSERV.
- Digest (traditional)
- Digest (MIME format)
- Digest (HTML format)
With a "digest" subscription, you receive larger messages (called
"digests") at regular intervals, usually once per day or once per
week. These "digests" are collections of individual list postings.
Some lists are so active that they produce several digests per day.
Digests are a good compromise between reading everything
as it is posted and feeling like the list is clogging your mailbox with
a multitude of individual postings.
There are three digest formats: a "traditional", text-only format; a
MIME format, which (with mail clients that understand MIME digests)
"bursts" the individual messages out of the digest so that you can read
them separately; and an HTML format, which requires an HTML mail clients.
- Index (traditional)
- Index (HTML format)
With an "index" subscription, you receive short "index" messages at
regular intervals, usually once per day or once per week. These "indexes"
show you what is being discussed on the list, without including the text
of the individual postings. For each posting, the date,
the author's name and address, the subject of the message and the number
of lines is listed. You can then download messages of interest from the
server (the index contains instructions on how to do that).
An index subscription is ideal if you have a slow connection and only
read a few hand-picked messages. The indexes are very short and you do
not have to worry about long download times. The drawback of course is
that you need to reconnect to order messages of interest from the server.
You can choose to have the index sent to you in either a traditional
format (plain text) or in HTML format with hyperlinks.
Mail Header Style
- Normal LISTSERV-style header
"Full" mail headers (normally the default), containing
Internet routing information, MIME headers, and so forth.
- LISTSERV-style, with list name in subject
"Full" mail headers (like the default) except that a "subject tag" is
added to the subject line of mail coming from the list. If there is no
subject tag defined in the list's configuration, the name of the list
will be used. This can be very useful for sorting and filtering mail.
- LISTSERV-style, short (advanced option)
These headers are similar to the normal LISTSERV-style header except
that Internet routing information and MIME headers are removed.
- "Dual" (second header in mail body)
Dual headers are regular short headers followed by a second header
inside the message body. This second header shows what list the message
is coming from ('Sender:'), the name and address of the person who
posted it ('Poster:'), the poster's organization, if present, and the
message subject. Dual headers are helpful if your mail client
does not preserve the original return e-mail address.
- sendmail-style (advanced option)
This option selects sendmail-style headers, i.e. an exact copy of
the original, incoming mail header with the addition of a 'Received:'
line and of a 'Sender:' field. Some technical people prefer this type of
- No acknowledgements
LISTSERV will not send any acknowledgement at all when you post to the
list. This is probably not a good setting unless you really
do not want any feedback from LISTSERV as to whether or not your posting
was received and distributed.
- Short message confirming receipt
Typically this is the default setting, although it can be overridden by
the list owner. If you choose this setting, LISTSERV will send you a
short message whenever you post to the list, confirming the distribution
of your message and telling you how many people it was sent to.
- Receive copy of own postings
Some people prefer this setting over the short acknowledgement message.
It tells LISTSERV to send you a copy of your own postings, so that you
can see exactly how it appeared on the list (useful if you are behind
an unreliable gateway or firewall).
- Mail delivery disabled temporarily
This option toggles the receipt of mail from the list. You may want to
disable mail delivery if you will be away from your mail for an extended
period of time.
- Address concealed from REVIEW listing
This option conceals you from the list of subscribers shown by the REVIEW
command. Note that the list owner and the LISTSERV administrator can
always get the complete list of subscribers, regardless of this setting.
Nowadays, most lists are configured so that only the list owner
can use the REVIEW command, but some lists still allow subscribers to
get a listing of all the other participants.
For lists with topics enabled (if the Topics: section of the form is not
visible, topics are not enabled), this section allows you to subscribe
or unsubscribe to all, some, or none of the available topics.
