It is.

Here's the appropriate section from /usr/src/linux/Documentation/Changes:

File Locking (Sendmail)
=======================

   As of pre2.0.6 (aka 1.99.6), mixed-style file locking is no longer
allowed.  For example, a file cannot be simultaneously locked with
`flock' and `fcntl'.  See Documentation/locks.txt for all the gory
details.  Among the programs this has impacted are older sendmails.  If
you get a message that sendmail cannot lock aliases.dir (or other
files), you'll need to upgrade to at least 8.7.x. The latest sendmail
is at ftp://ftp.cs.berkeley.edu/ucb/src/sendmail/sendmail.8.7.5.tar.gz.
