images partially missing in incoming emails as if downloading quit part way through
Recently I'm receiving emails in which the sender has included a photo or movie file and there's only a beginning portion there. I'll get the top half of a photo, or 10% of a movie short 30-second movie. The whole file can be downloaded from the Yahoo site, but it doesn't come through via Thunderbird.

do you have something scanning incoming email? They can at times cause issues with truncated attachments.
Not that I know of. This only started in the last month or so, and I haven't done anything recently that I could have caused this.
dierks66,
I have experienced this problem twice that I know of with picture and video attachments. These attachments are b64 encoded and are incomplete (there is no terminator at the end of the b64 section) in Thunderbird when you View Source. However, if I log into AOL webmail directly, the attachments are complete. I have Thunderbird configured for IMAP. In Thunderbird, if you move these incomplete messages to a local folder, Thunderbird deletes the complete message from the server and leaves you with an incomplete message in your local folder. I have used Outlook and Windows Live Mail in the past and never had such a problem. I view Thunderbird's occasional corruption of messages as a serious bug because it renders Thunderbird unreliable.
sfhowes, I tried changing the preference mail.server.default.fetch_by_chunks to false as you suggested, but it didn't solve my problem. Today I received a large email (2.4 MB) that had 9 attachments. The first two came through fine and only part of the 3rd (a pdf) was received. The other 6 attachments did not appear in TB. However, if I logged into my AOL email account with AOL webmail, or Outlook 2013, or Window Live Mail all 9 attachments were there in their entirety. In TB, after making the preference change, I cleared the cache and did CTRL-U in an attempt to force the re-download of this email, but it had no effect. I also moved the email from my IMAP inbox to IMAP drafts and back again to IMAP inbox with no effect in TB. When viewing the source for this email, it appears that TB or the AOL IMAP server interrupts the message download for some unknown reason. TB has downloaded larger emails in the past without issue, so size is not the sole cause of the problem. The message size on the server is 2.4 MB vice the 408 kB that TB downloads. This is the third time I have verified that TB failed to completely download a message. I can provide a copy of the complete .eml source from the server and copy of the .eml that TB downloads. Any further suggestions?
