When a Mail Express user sends an email with an attachment, the attachment (if managed by Mail Express) is sent to the Mail Express Server, and the recipient receives an email that contains the body of the original sent email, plus one or more hyperlinks from which the recipient can download the attachment. The attachment is not processed by the SMTP server nor sent to the recipient's email client. The link to the attachment is embedded in the email.
The URL for the Pick-Up Portal is https://<server URL>/pickup. The Pick-Up Portal must be enabled for recipients to download attachments. You may want to disable the Pick-Up Portal for things like troubleshooting, security issues, or maintenance.
You enable or disable the Pick-Up portal on the Pick-Up Portal Configuration page.
To enable the Pick-Up Portal
Launch the Mail Express Server administration interface. (e.g., click Start > Programs > Globalscape > Mail Express > Mail Express Admin or double-click the desktop shortcut).
Log in using the Mail Express Server administrator username and password that you specified during installation of the server.
In the navigation pane, click Portal Settings > Pick-up Settings. The Pick-up Portal Configuration page appears. The URL for the Pick-Up Portal appears under General Settings.
Select the Require verified user to allow only verified users access (no anonymous access) to the Pick-Up Portal.
Click Save to save your changes, or click Restore to reset the boxes to their previous setting. If you navigate away from the page without clicking Save, your changes are discarded.
