postal-list(1) Postal postal-list(1)
NAME
postal-list - program to show how postal expands user names
SYNOPSIS
postal-list user-list-filename conversion-filename
DESCRIPTION
This program shows the expansion that the postal program uses on email addresses. This can be used to make sure that you're configuration
files do what you expect them to, and can also be used to produce a list of user-names for an account creation script (in case you want to
create a million test accounts in a conveniant fashion).
The user-list-filename is the name of a file which contains a list of user's email addresses. This can be just user-names or fully quali-
fied email addresses.
The conversion-filename parameter will be the name of a file containing the conversions to apply to email addresses. Each line in the file
can either be a comment (starting with "#") or is to contain two parameters. The first parameter is the regular expression. For each
email that is to be sent a randomly selected user-name will be checked against all regular expressions, the first match will determine the
translation that is to be applied. The translation will be the second parameter on the line. It will contain a number of "." characters
specifying characters in the name that are not to be translated. To specify the translations a range of characters can be specified inside
square brackets. For example to have every address starting with "a" have a character from "01234567890abc" as it's second character and a
character from "xyz" as it's third character you would have the following: ^a .[0-9abc][xyz]
