Transfer Notification

Purpose

Alerts and reminds recipients of a received transfer

Details

After uploading a transfer, the server notifies the recipients of the transfer by sending a notification email. The email contains the following information:

sender
recipient
subject
message, including signature
URL where to download the transfer
information about the files included in the transfer
information about the malware status of files, if malware protection is enabled
information about the hashsums of files, if hashsum calculation is enabled
the expiration time, after which the transfer will be deleted

Notification emails are sent in the language the recipient has requested.

The initial notification email is sent as part of the post-processing after the transfer has been uploaded. Afterwards, the server can renotify recipients of unread transfers after a given interval, until either the transfer has been read, has expired or the maximum number of notifications has been reached.

Notification emails use a number of SMTP headers in a particular way, to handle replies and email bounces properly.

From is not set to the email address of the sender, but to a “technical” address, typically www-data@{storagehost}.
Return-path is set to the same technical address.
Reply-to contains the email address of the sender.
X-Skp-Id is set to the type of notification and the recipient ID of the transfer.
X-Skp-Host holds the FQDN of the storagehost.
the Message-Id is a combination of X-Skp-Id, a precision timestamp and X-Skp-Host.

Emails are sent in multipart/mime format, with both a plaintext alternative and a HTML alternative.
