Requirements for connecting to content on the hosted FTP server

The hosted FTP server that can provide external content to email messages is part of HCL Unica. Content from the hosted server is provided over an encrypted FTP connection. The connection to the server, and the content that you upload, must meet certain requirements.

To connect an email to content on the FTP server, your hosted messaging account must have valid login credentials to the FTP server. The FTP connection requires specific access credentials. Do not attempt to connect to the FTP server with the credentials that you use to upload recipient information in an Output List Table (OLT).

Your local HCL Unica environment and the hosted FTP server communicate over passive FTP. The system supports two passive FTP methods, explicit FTP and implicit FTP.

The local HCL Unica installation and HCL Unica Hosted Services establish FTP communication over the ports listed in the table.

Port Type Explicit FTP Implicit FTP
FTP command port Port 21 Port 990
FTP data upload ports

(US data center)

ports 15393 to 15424 ports 15600 to 15701
FTP data upload ports

(UK data center)

ports 15393 to 15443 ports 15600 to 15650

HCL Unica never initiates a connection with your local network. It only responds to connection requests initiated from behind your firewall.

You can upload only HTML or text files with the following file extensions to the hosted FTP server.

  • .html
  • .htm
  • .txt

The combined size of all files that you upload to the hosted FTP server cannot exceed 250 MB. After you upload files to the FTP server, the files are immediately available for selection when you configure a content connection.

The names of the files on the hosted FTP server must exactly match the file name that is specified in the content connection. If you rename a source file on the FTP server, you must update the file name in the corresponding content connection.
