Never accidentally send an email without an attachment again with the Attachment Alert Zimlet!

Hi Zimbra Customers, Partners & Friends,

How many times have you clicked Send on an email then thought, “Darn! I forgot to add the attachment!”? The Attachment Alert Zimlet warns you if you try to do it again! How? The Zimlet looks at the body of an email when you click Send. If it finds words like “attach”, “attachment” and “attached’, but there is no attachment, it pops up a reminder to upload the attachment. Cool!

For Non-Techies … To install the Attachment Alert Zimlet without developing the code, download a pre-built zip from the Github releases page and install it by running zmzimletctl deploy zimbra-zimlet-attachment-alert.zip

For Techies … The Attachment Alert Zimlet listens for an event using zimletEventEmitter. Read on for the details …
