Background: importing a mbox file containing ~700 messages (20 MB).
Our program splits MULTIAPPENDS into approx. 5MB chunks. We don't use
literal+ in order to immediately catch errors.
I can reproducibly produce the following error (2.2.2) when doing a
MULTIAPPEND where every append is using literal8:
[...340 messages appended in 7 previous APPEND commands...] C: 10 APPEND Test "16-Dec-2011 17:19:46 -0700" ~{3128} [...~30 APPENDed messages...] C: "18-Jan-2012 12:38:21 -0700" ~{2893} S: + OK [...2893 octets of data...] C: "18-Jan-2012 22:09:41 -0700" ~{6492} S: 10 BAD Error in IMAP command APPEND: Expected '{' S: 492} BAD Error in IMAP command : Unknown command.
This error occurs about 340 messages in. If I switch to using regular
literals, this error does not occur. I can verify that neither the
12:38:21 message nor the 22:09:41 message alone is broken (I can put
just these two in a file and import and it is successful).
I can provide the mbox file privately, if needed.
