Patches for the sendmail binary

Known problems in sendmail 8.11

sendmail 8.10

Known problems in sendmail 8.10

There is a problem on some Solaris versions with putc() which returns EOF if 0xff is used as argument and the buffer is flushed. A patch based on the changes made for sendmail 8.11 should fix the problem; otherwise e-mails which contain 0xff may "grow" to huge sizes.

Known problems in sendmail 8.10.0

sendmail 8.10.0 has the following known problems (which were discovered after the release by some users): Both problems are fixed in sendmail 8.10.1.

Known problems in sendmail 8.10 caused by other software

sendmail 8.10.{0,1} seems to have a problem on Solaris 7 and 8 when used in conjunction with Berkeley DB 3 if both are compiled with gcc instead of Sun's C compiler. Apply a patch from Sleepycat.
