Re: Review - draft-ietf-imapapnd-appendlimit-extension-05

Thanks Alexey.

We will incorporate the command and update the draft.

SM/All,

Kindly share your comments as well.

This extension provides server admins with the capability to configure the maximum append limit size they will be expecting from the client. IMAP server side processing of huge attachments above the available limit can be avoided to a great extent, if this extension is supported by the IMAP client.

Jay

I think "is supported by" is mor correct, but otherwise this looks good.

Thanks & Regards

Dear SM,

1. Introduction



Several IMAP server have limitation for mail upload size which is not

published to the email client.  When email client APPEND a mail with

huge attachments, it fails due to size restriction set by the IMAP

server.  This results in unnecessary resource usage.  Especially in the

mobile device environment, appending mail with huge attachment consumes

device resources like device battery power and mobile data.



The IMAP APPENDLIMIT extension provides an ability to advertise maximum

upload size allowed by the IMAP server, so that email client knows the

size limitation beforehand.



This extension provides server admins with the capability to configure the maximum append limit size they will be expecting from the client. By implementing this extension, IMAP server side processing of huge attachments above the available limit from the IMAP client can be avoided to a great extent.


This is an improvement. This doesn't help if the client doesn't support the extension, but in the context of this document this is probably obvious, so doesn't need saying. (I was just wondering whether "the IMAP client" in the last sentence is clear or needs clarifying.)




Regards,

Jay

There is the following text in the Introduction Section of

draft-ietf-imapapnd-appendlimit-extension-05:



   "This results in unnecessary resource usage.  Especially in the

    mobile device environment, appending mail with huge attachment

    consumes device resources like device battery power and mobile data."



I read that as: this results in unnecessary usage in the mobile device environment as it increases the consumption of device battery power and mobile data, i.e. it only benefits IMAP clients in a mobile environment.



Could you post some text about how the extension might help the IMAP server to the mailing list?  The Working Group can then discuss about that text and agree on what text to add.

S. Moonesamy
