Which Version of Sendmail?
• Too many versions:
– v8.9.3 is stable, no known security holes
– v8.10 was a major feature release
– v8.11.x is the current version
This course covers Sendmail v8.11
In the past, it was usually the case that administrators always wanted to be running
the latest version of Sendmail– mostly because new versions of Sendmail were
created whenever a security problem was discovered. At this time, however,
Sendmail v8.9.3 has been in use for a long time and we still don't know of any
security problems in this version of the code. v8.9.3 is a known stable release that
is still in use on a lot of systems.
Sendmail v8.10 was the largest feature release in Sendmail history– made possible
by the work of the engineering team at Sendmail.COM. While many of these new
features are useful, new features/code implies that new bugs may have been added
as well. Sendmail v8.10 was followed by v8.11 (v8.11 includes crypto support and
support for SMTP AUTH)– the latest version as of this writing is v8.11.3.
If you don't need all of the features that were introduced in Sendmail v8.10 and
v8.11, then perhaps you may be more comfortable staying with v8.9.3. This course
uses Sendmail v8.11.3 for its examples because we want to make use of the new
anti-spam features in the latest version. For more information on new features
introduced in Sendmail v8.10, check out:
