Forwarding an Email(with attachments) without downloading the actual attachments

I want to forward an Email which has some attachments.

  • I don't want to download the attachments and then upload again the same attachments
  • I want to achieve this functionality on IMAP servers like (Gmail, Yahoo, etc)
  • For outlook account, I have achieved this using smart forward concept but that does not apply on IMAP
  • I am developing an Android application

I tried URLAUTH IMAP extension with Gmail server but that does not work - In response to GENURLAUTH request, server responded the unknown request

I checked with Gmail app and Microsoft Outlook Android app and they already provide this feature

Expected result - Emails are forwarded on Gmail/Yahoo servers without actually downloading the attachments on your mobile devices.

Please suggest how this functionality can be achieved on Gmail server

Sorry. It can't be done with baseline IMAP. There are extensions for that (URLAUTH and other Lemonade friends) but they are rarely deployed.

The Gmail app does not use IMAP for Gmail accounts. Use the Gmail HTTP API for Gmail, which is somewhat richer than IMAP.

The Outlook APP also does not use IMAP for outlook accounts. It uses either EAS or the various Microsoft HTTP Email APIs.
