Bug Fix Advisory

Topic

Updated sendmail packages that resolve an issue are now available for Red Hat
Enterprise Linux 5.

Description

Sendmail is a widely used Mail Transport Agent (MTA). MTAs deliver mail from one
machine to another. Sendmail is not a client program, but rather a
behind-the-scenes daemon that moves email over networks or the Internet to its
final destination.

These updated sendmail packages fix the following bug:

• Sendmail previously used the MAXHOSTNAMELEN macro to allocate buffers
  containing host names and Fully Qualified Domain Names (FQDNs). The value of the
  MAXHOSTNAMELEN macro is set to 64 on Red Hat Enterprise Linux systems, which
  means that such allocated buffer can hold at most 63 characters, but according
  to the RFC1035, the FQDN maximal length is defined to 255 characters. This
  caused problems with a FQDN resolution in case that FQDN was longer then 63
  characters. With this update, the code has been modified so that the size of
  buffers containing FQDN is now set to 256 bytes. The issues with the FQDN
  resolution now no longer occurs. (BZ#726094)
  

All users of sendmail are advised to upgrade to these updated packages, which
resolve this issue.
