Greetings,
I am attempting to back up my SMTP gateway to either an FTP or SFTP server. I have used this same FTP server software (freeftpd) on a different server without issue. When I attempt to do a manual backup or the system tries to do a schedule backup, the following messages show up in the logs on the SMTP Gateway;
May 12 2017 08:09:30 [Thread-4080] [ScriptHelper] ERROR - Cannot backup the database.
May 12 2017 08:09:30 [Thread-4080] [ScriptHelper] ERROR - FTP:Can't transmit the file: Opening BINARY mode data connection for //db-backup.10.6.2-7.brightmail.May-12-17-08-07.full.manual.tar.bz2ERROR: Unable to send to the specified URL.
May 12 2017 08:10:11 [Thread-4085] [ScriptHelper] ERROR - Cannot backup the database.
May 12 2017 08:10:11 [Thread-4085] [ScriptHelper] ERROR - Failed to transmit the file: Error: last line returned was: lost connectionERROR: Unable to send to the specified URL.
This server works with several other applications to back up their data via SFTP. I have tried clearing the known hosts on the SMTP gateway with no luck. Does anyone have any ideas on how to get this working again?
Thanks
