The starting options are;

-b bcc-list

This allows a list of people to receive blind-carbon copies, or BCCs, of the message. This list should be full email addresses.

-c cc-list

This allows a list of people to receive carbon copies, or CCs, of the message. This list should be full email addresses.

-C comments

This allows a Comments: line to be added to the RFC822 header with any text you desire.

-d

Debug. This is helpful for strange, unfriendly errors from the program (etc).

-f from

This overrides the users name in the From: line, so that if the user was x@y, and their name was MrX then the default From: line would be "From: x@y (MrX)". Using "-f Joe" when invoking this, though, would change it to "From: x@y (Joe)"

-i msg-id

This allows a message-id to which this message refers.

-r replyto

Occasionally, you might send mail but want the replies to go to a different address (very common with mailing lists). There is a header for this purpose called "Reply-To:" which can be utilized by using this starting option. For example, we could send mail with a reply-to to list-request by using "-r list-request". The header generated would then be of the form "Reply-To: list-request".

-R references

This allows descriptive/reference text for this message.

-s subject

The subject of the message is specified by using this starting option.

Either the name of the file containing the message, or a - to indicate usage of standard-in is required.

   #
   # Batch Mail - batch mailing of a file to a LOT of users
   #
   # Usage: batch-mail "from" "subject" filename

   sender_copy = $LOGIN
   replyto = "The-Mr-Big-list"

   fastmail -b $sender_copy -r $replyto -f "$1" -s "$2" $3 person1
   sleep 10
   fastmail -r $replyto -f "$1" -s "$2" $3 person2
   sleep 10
   fastmail -r $replyto -f "$1" -s "$2" $3 person3
   sleep 10
   fastmail -r $replyto -f "$1" -s "$2" $3 person4

   < etc >

with the invocation:

   batch-mail "Mr. Big" "Warning to all" warning.text

    From: big-vax!big (Mr. Big)
    Subject: Warning to all
    Reply-To: The-Mr-Big-list
