"It turned out that the sendmail binary depends on libsasl2 (>=
2.1.19.dfsg1) which is neither available in the stable nor in the
security archive. This version is scheduled for the inclusion in the
next update of the stable release, though.

You'll have to download the referenced file for your architecture from
below and install it with dpkg -i.

As an alternative, temporarily adding the following line to
/etc/apt/sources.list will mitigate the problem as well :

  deb http://ftp.debian.de/debian stable-proposed-updates main

Here is the original security advisory for completeness :

  Frank Sheiness discovered that a MIME conversion routine in
  sendmail, a powerful, efficient, and scalable mail transport agent,
  could be tricked by a specially crafted mail to perform an endless
  recursion."
