- Testing Sendmail Configuration files
-
- I have written some shell scripts called "showhow" and "showwhere"
- that can be used to test your sendmail configuration file.
-
- You create an input file with a set of addresses to test. You run the
- script and it generates an output file, showing the results of each
- address. When I make a major change to a sendmail file, I run the test
- suite on it, comparing the results with the last time I tested the
- address. I can use this to see in any of the 400 addresses in my test
- suite will behave differently with the new configuration file. My
- addresses won't help you, so you have to be creative and add your own.
- Here are some guidelines.
-
- The format or the input file debug.in is:
- rulesets address
- or
- rulesets address comment
-
- Use the second if ruleset does not start with a '0'. I'll explain this later.
-
- Example:
-
- 0 user@some.do.main
- 0 site!user%site2@site3.com
- 22,4 user@localsite Sender_via_UUCP
-
- where 22 is a mailer rewrite ruleset for a mailer (i.e. UUCP).
-
- Ruleset 0 must be avoided when testing the re-write rules for
- mailers because ruleset 0 outputs a triple (user, host, mailer),
- and only one part (user) passed to the mailers.
-
- The makefile generates a file in tbl(1) format that
- lists the following:
-
- ruleset address mailer hostname user
-
- Showing the resolved triplet for each address
-
- I think the scripts I have will work on IDA, SunOS 4.0, and Ultrix 3.0
- sendmail executables. The problem is that older sendmails output debug
- info using ^V, etc. instead of $#. The script is set up to work with
- Ultrix 3.0. The sendmail with SunOS used a different set of
- characters to indicate the results of a rule (^W instead of ^V).
-
- I have set up a makefile in the debug directory that you can use
-
- make - tests your sendmail file against a known good file
- good.out. Once you have a working set of rules, copy
- debug.out to good.out
-
- make report will print a table of all of the addresses resolved to the address, mailer, and hostname
