Free qpopper 4.0.18 software for linux

Shadow password file utilities package includes the programs necessary to convert traditional V7 UNIX password files to the SVR4 shadow password format, and additional tools to maintain password and group files (that work with both shadow and non-shadow passwords).
Enhancements:
- A problem where su set the enviroment too early when using PAM was fixed.
- A UID/GID overflow in groupadd, groupmod, useradd, and anusermod was fixed along with overflows in inactive, mindays, warndays, and maxdays in passwd, useradd, and usermod. groupmems was rewritten to use PAM and getopt_long().
- usermod was reverted back to previous -a option semantics.
- chsh and groupmod were rewritten to use getopt_long().
- Translations and man pages were updated.

EXACT is a UNIX daemon that provides mail relay control. It is written for those who operate a mailserver and wish to allow mail relaying, conditionally on users authenticating to an IMAP or POP server.
It supports UW-imap, Qpopper, Cyrus, Perdition, TeaPOP, cucipop, EXIM, Postfix and Sendmail out of the box.
It will work as is with these POP/IMAP servers:
- UW-IMAPD
- Cyrus
- Courier (IMAPD and POPD)
- Perdition
- Qpopper
- TeaPOP
- Cubic Circles cucipop
and these MTAs:
- Exim
- Sendmail
- Postfix
Installation:
The `configure shell script attempts to guess correct values for various system-dependent variables used during compilation.
It uses those values to create a `Makefile in each directory of the package. It may also create one or more `.h files containing system-dependent definitions.
Finally, it creates a shell script `config.status that you can run in the future to recreate the current configuration, a file `config.cache that saves the results of its tests to speed up
reconfiguring, and a file `config.log containing compiler output (useful mainly for debugging `configure).
If you need to do unusual things to compile the package, please try to figure out how `configure could check whether to do them, and mail diffs or instructions to the address given in the `README so they can be considered for the next release.
If at some point `config.cache contains results you dont want to keep, you may remove or edit it.
The file `configure.in is used to create `configure by a program called `autoconf. You only need `configure.in if you want to change it or regenerate `configure using a newer version of `autoconf.
The simplest way to compile this package is:
1. `cd to the directory containing the packages source code and type `./configure to configure the package for your system.
If youre using `csh on an old version of System V, you might need to type `sh ./configure instead to prevent `csh from trying to execute
`configure itself.
Running `configure takes awhile. While running, it prints some messages telling which features it is checking for.
2. Type `make to compile the package.
3. Optionally, type `make check to run any self-tests that come with the package.
4. Type `make install to install the programs and any data files and documentation.
5. You can remove the program binaries and object files from the source code directory by typing `make clean. To also remove the files that `configure created (so you can compile the package for a different kind of computer), type `make distclean.
There is also a `make maintainer-clean target, but that is intended mainly for the packages developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution.
Enhancements:
- Bugfix release. Building without db didnt work.
- Also changed back to dbmnz format for the db, because the other format seemed to cause exim problems.
