Unable to Upload Files to File Storage

When attempting to upload files to file storage, the process does not complete. On mail servers with this problem, SmarterMail is using a public IP for the communication between the Web interface and the SmarterMail service when doing a file upload to file storage. SmarterMail uses ports 17001 and 17002 for this type of communication and these ports generally are not open in a firewall.

This issue may present with the following error: "Error uploading one or more files. Please verify that the file does not exist and is not of a restricted type." NOTE: If using IIS 7.0, ensure that the application pool utilized by SmarterMail is set to integrated mode.

Applies to SmarterMail 8.x - 15.x

Resolution 1:
Change the remote service to use IPC instead of TCP for it's communication protocol.

1. Open the web.config file. By default, it is located in C:\Program Files\SmarterTools\SmarterMail\MRS.
2. Find and change the value in the following line from 127.0.0.1 to IPC:

   <add key="MailServiceAddress" value="127.0.0.1" />

• Save the file.

Resolution 2:
Open ports 17001 and 17002 in your firewall. You probably won't need to open these ports for all IP addresses, just those IP addresses used by the SmarterMail server.
