SMTP and can optionally be installed with SQL support.

-------------------------------------------------------------------
NOTE: Certain packages are still vulnerable. Users should migrate
to another package if one is available or wait for the
existing packages to be marked stable by their
architecture maintainers.
Description
===========
It was discovered that the sendmail.cf file is mishandled in a popen
call.
Impact

A remote attacker, by enticing a user to open an e-mail attachment,
could execute arbitrary shell commands.

Gentoo has discontinued support for SquirrelMail and recommends that
users unmerge the package:
