How do I filter mail?
Using Account Services to filter spam
Please see How do I stop junk e-mail by turing on spam filtering?.
Using shell access for advanced filtering
You can use the "filter" program to deal
automatically with incoming mail in a number of ways: you can save
messages from certain people or about certain subjects to specific
folders, or you can delete mail from certain people without even having to
see it.
To set up filtering, you'll need to create a file called ".forward" in
your home directory, and then set up a filter-rules file.
- type unix and press enter
- type pico .forward
- in the .forward file, type in the following line:
"|/usr/local/bin/filter"
type it at the very start of the file, and include the
double-quotes.
- type ctrl-x, and type y to save changes to the
file.
If you already have a .forward file, just add the line at the
beginning of the file and separate it from the forwarding address with a
comma:
"|/usr/local/bin/filter", user@someother.account.edu
- type cd .elm
- type pico filter-rules
- Type the information below into the file:
# $HOME/.elm/filter-rules
#
# filter rules for the elm filter program.
#
# rule 1
#
if from friends@somehost then save "~/Mail/friends"
#
# rule 2
if from spam@spamhost then delete
#
- Rule 1 will save messages from friends@somehost to a folder called "friends" in
your Mail folder. (You can name the folder anything you'd like.)
Rule 2 will delete any messages from spam@spamhost.
Make sure the username or address looks like it does in the "from"
line of any e-mail you've received from them. Any part of the address
will work, so just the username is fine, as long as it's exact.
If you only want to delete messages, just delete the line under "rule 1".
- type ctrl-x, and type y to save changes to the file.
- type "cd .." without the quotes
- type menu
From now on, any mail from the address "xxxxx" will be
automatically saved to a folder called "friends" -- you won't ever see it
in your inbox. Messages with the address "yyyyy" will be deleted
automatically.
You can check this by putting your own username in first, and sending
yourself mail. When you're sure you are not receiving it, take your name
out.
You can make a separate rule for each address you would like to
save, or delete, or copy.
