Hi. I followed the tutorial: Perfect Server - CentOS 5.3 x86_64 [ISPConfig 3]. At first, thanks for bringing this wonderful tutorial. Everything worked out as expected, with only minor issues. However, I have a problem with postfix. When the service starts, everything seems to be OK, but the mail log shows the following error: Code: fatal: unsupported dictionary type: mysql The SMTP port (25) is open, but after I connect nothing happens. I read in another forum that this means postfix lacks mysql support. Their suggestion is to remove the original postfix package and install the following package from the CentOS Plus repository: Code: postfix-2.3.3-2.1.centos.mysql_pgsql.x86_64.rpm Is it safe to do this? Will this break the ISPConfig's postfix configuration? Thank you.
