On RedHat Linux 7.0 you must install the db3-devel RPM before you can compile
8
the Postfix source code.
10
Warning: do not use multiple Berkeley DB versions. Every Postfix program will
11
dump core when it is built with a different Berkeley DB version than the
12
version that is used by the system library routines. See the DB_README file for

PPrrooccmmaaiill iissssuueess
17
On RedHat Linux 7.1 pprrooccmmaaiill no longer has permission to write the mail spool
18
directory. Workaround: chmod 1777 /var/spool/mail.

LINUX ssyyssllooggdd uses synchronous writes by default. Because of this, ssyyssllooggdd can
23
actually use more system resources than Postfix. To avoid such badness, disable
24
synchronous mail logfile writes by editing /etc/syslog.conf and by prepending a
25
- to the logfile name:
28
mail.* -/var/log/mail.log

Send a "kkiillll --HHUUPP" to the ssyyssllooggdd to make the change effective.
