- Mail Express, v4.2 and later
NOTE: We haven't tested this in older versions, but it should work.
When a client receives an attachment via Mail Express, the email also include an attachment with the package identifier. This file, as shown below, has no useful data and is primarily used as static icon to allow recipients to sort/filter for emails with attachments. However, because of the file name, some clients think this could be a malicious email and are not willing to accept the email. While the icon cannot be removed, we can change the name of the file from the unique package id to something more friendly.
To change the extension or file name
- Stop the Mail Express service and browse to the following folder, depending on the operating system and installed version:
“C:\Program Files\GlobalSCAPE\Mail Express\webapps\ROOT\WEB-INF\classes\META-INF”
“C:\Program Files (x86)\GlobalSCAPE\Mail Express\webapps\ROOT\WEB-INF\classes\META-INF”
- Locate the file named staticConfig and make a backup of this file. (Right-click the file, click Copy, then click Paste.)
- Open staticconfig in a text editor and browse down to the following section:
<bean id="attachmentNamePattern" class="java.lang.String">
<constructor-arg value="Package_%s.html />
<meta key="Description" value="The format for the name of the small HTML file attached to emails …" />
- In <constructor-arg value'"Package_%s.html />, change the text in the quotations marks to what you would like the filename or extension to be. Be sure to maintain the quotation marks.
- Restart Mail Express and send a test message to confirm successful changes.
