634044 - KB article: IMAP fetch by chunk preference to fix corrupt attachment problem

Status: RESOLVED INVALID

(support.mozillamessaging.com Graveyard :: Knowledge Base Articles, defect)

Description

[Roland Tanglao needinfo please :rolandtanglao, :mohnkuchen, :adobo, :sinigang, :roland]

document IMAP fetch_by_chunks preference workaround for Thunderbird and Exchange as well as Thunderbird and Gmail and finally Thunderbird and certain IMAP servers (like gmx, we've had a few reports of this)
i.e. synthesize the knowledge here:
* gmail may or may not have fixed the bug but google recommends turning it off as an "IMAP enhancement" http://mail.google.com/support/bin/answer.py?answer=78892
* http://getsatisfaction.com/mozilla_messaging/topics/attachments_become_invalid_when_downloaded_using_thunderbird#reply_1389914
* If you are using IMAP as your mail protocol, change:
mail.imap.fetch_by_chunks
mail.server.default.fetch_by_chunks
* bug 92111 (not sure if this an Exchange bug or a Thunderbird bug, my guess would be both)
to false by following instructions here: http://forums.mozillazine.org/viewtopic.php?f=39&t=858335&start=0&st=0&sk=t&sd=a
* http://kb.mozillazine.org/Entire_message_fetched_when_opening_a_IMAP_message
* http://kb.mozillazine.org/IMAP:_advanced_account_configuration
* bug 390795 attachments corruption for IMAP account (truncated due to estmated/incorrect RFC822.SIZE even though server is not MS Exchange)
