To fix the problem it’s sufficiet to modify the following parameter:
default_vsz_limit = 512M
On Centos 7 it’s located in:
/etc/dovecot/conf.d/10-master.conf
Not that hard to solve problem.
To solve this problem:
Can't locate File/Which.pm in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) BEGIN failed--compilation aborted
you just need to install perl-File-Which package:
yum install perl-File-Which
There’s a bug in rpm package: https://bugzilla.redhat.com/show_bug.cgi?id=304121
It causes the following error while building rpm packages:
/usr/lib/rpm/debugedit: canonicalization unexpectedly shrank by one character
As a workaround you can use this command:
rpmbuild -bb rpmbuild/SPECS/package.spec -D 'debug_package %{nil}'
It will disable building of debug package and that’s it.

If you need to install ionCube loader on Centos 6.4 you will need either to enable Atomic repository on your Linux box or to download their SRPM package and rebuild it.
Way 1
wget -q -O - http://www.atomicorp.com/installers/atomic |sh
yum install php-ioncube-loader
Way 2
rpm -ivh rpmbuild/RPMS/x86_64/php-ioncube-loader-4.2.2-2.art.x86_64.rpm
rpmbuild -bb ~/rpmbuild/SPECS/php-ioncube-loader-art.spec

fail2ban is a simple daemon (written in Python, BTW) which monitors your Linux server logs and is able to prevent bruteforce attacks by adding bad IP addresses to iptables. This is a simple self reminder on how to setup it.
yum install fail2ban
vim /etc/fail2ban/jail.conf
If you want fail2ban to only notify you (and not add them to iptables) modify the configuratio files this way:
action = sendmail-whois[name=SSH, [email protected], [email protected]]
It would be wise to add your IP addresses to be ignored:
ignoreip = 127.0.0.1/8
Start:
service fail2ban start
Enable auto start:
chkconfig fail2ban on
Now if somebody tries to brueforce your SSH you’ll get a mail.
