comment Postfix virtual domain mapping user for a user a linux name containing @
There is no directives should be in main.cf about virtual domains. I'm not sure how your answer will help me to solve my problem. The problem is, that Postifix needs additional settings (if there are any in this concern) to make it work.

comment SELinux remove or leave the old SSH port label?
@MichaelHampton What if you use port scan detection and block such attempts. (blacklisting ips that trying to get to undefined ports)? Why it's not possible to run the following command semanage port -d -t ssh_port_t -p tcp 22 and delete default port? I get error like this: Port tcp/22 is defined in policy, cannot be deleted

comment How to check if internet IP address is currently taken?
@Moak It's hard to tell if ISP owns the IP but if you already owned an IP from the same network class (en.wikipedia.org/wiki/Classful_network), then you can suppose that your ISP could possibly assign that IPs. For example, if your IP ever was 1.2.1.2, then you could think that your ISP is able to assign 1.2.1.1-255.

@Moak It means that you can not use this IP, as it's already assigned.

comment uploading files greater than 1MB = connection resets
hmm.. alright, sorry. You just had setup PHP upload_max_filesize = 1000M and I wouldn't think that 1MB uploads could ever fail! Just wanted to double-check.
