So I’ve decided to fix it.

Added UseReverseDNS off to config file — didn’t help.

Added GoogleDNS (8.8.8.8) to resolv.conf — didn’t help.

Added IdentLookups off to proftpd.conf — helped.

Thanks to Ray Dehler.

When IdentLookups is turned on it means that Proftpd is trying to identify the remote username via ident (RFC1413) protocol.
