  • Add EPEL Repository which is provided from Fedora project.
# yum -y install epel-release

set priority=5

# sed -i -e "s/\]$/\]\npriority=5/g" /etc/yum.repos.d/epel.repo

change to enabled=0 and use it only when needed

# sed -i -e "s/enabled=1/enabled=0/g" /etc/yum.repos.d/epel.repo

if enabled=0, input a command to use the repository

# yum --enablerepo=epel install [Package]
  • Add RPMforge Repository which provides many useful packages.
# yum -y install http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.3-1.el7.rf.x86_64.rpm

# sed -i -e "s/\]$/\]\npriority=10/g" /etc/yum.repos.d/rpmforge.repo

change to enabled=0 and use it only when needed

# sed -i -e "s/enabled = 1/enabled = 0/g" /etc/yum.repos.d/rpmforge.repo

if enabled=0, input a command to use the repository

Performance: a high load of DSN success notification requests could slow down the queue manager. Solution: make the trace client asynchronous, just like the bounce and defer clients. Problem reported by Eduardo M. Stelmaszczyk of terra.com.br. Files: global/abounce.[hc], *qmgr/qmgr_active.c (the qmgr_active.c files are identical).

Bugfix (introduced Postfix 2.3 and Postfix 2.7): the Milter client reported some “file too large” errors as temporary errors. Problem reported by Michael Tokarev. Files: milter/milter8.c, cleanup/cleanup_milter.c.

  • 20110426

Bugfix (introduced in Postfix 1.1, duplicated in Postfix 2.3, unrelated mistake in Postfix 2.7): the local(8) delivery agent ignored table lookup errors in mailbox_command_maps, mailbox_transport_maps, fallback_transport_maps and (while bouncing mail to alias) alias owner lookup. Problem reported by William Ono. Files: local/command.c, local/mailbox.c, local/unknown.c, local/bounce_workaround.c.

Bugfix (introduced Postfix 2.6 with master_service_disable) loop control error when parsing a malformed master.cf file. Found by Coverity. File: master/master_ent.c.

  • 20110602

Workaround: some Spamhaus RHSBL rejects lookups with “No IP queries” even if the name has an alphanumerical prefix. We play safe, and skip both RHSBL and RHSWL queries for names ending in a numerical suffix. File: smtpd/smtpd_check.c.
