Hello people,

I'm running a VPS in DigitalOcean with Ubuntu Server 12.04.
Everything was working fine for more than 1 month. But in 05/17 the iredmail suddenly stoped working.
In the server I have two websites, the www.nudemail.tk with the iredmail, and the www.nudestay.com.br with a wordpress plataform.

I don't know why it stoped working, the last changes I made is to install a ftp server for wordpress, because it doesn't working fine without a ftp server. So, looking in my history:

192 apt-get install vsftpd 
193 nano /etc/vsftpd.conf 
194 mkdir /home/jackson/files 
195 chown root:root /home/jackson/ 
196 sudo service vsftpd restart 
199 chown -R www-data:jackson /var/www 
200 a2enmod rewrite 
201 nano /etc/apache2/sites-enabled/000-default 
202 nano /etc/apache2/sites-enabled/nudestay.com.br 
203 /etc/init.d/apache2 restart

May the vsftpd would be the responsible for the iredmail stoped working?
May is the a2enmod rewrite?
I don't know, the changes are in nudestay.com.br, a wordpress blog, not in nudemail.tk (the iredmail server).
Both are in the same server, may the rewrite or vsftpd would affect the iredmail functionality?
Any tips? Any help?

I need that to work, I was until 05/17 without sending my job e-mails. D:
Rope in the neck.

Thanks people, I love you!
