Hello,
wondering why it's still an issue with current git, while this old
working solution exists (tested with dovecot 2.22 and rspamd 1.4) :

Hello,
I'm bumping this because it still occurs with dovecot 2.2.22.
my dovecot-antispam plugin configuration :
antispam_allow_append_to_spam = no
antispam_backend = pipe
antispam_pipe_program = /usr/bin/rspamc
antispam_pipe_program_args = -h;127.0.0.1:11334;-P;********
antispam_pipe_program_notspam_arg = learn_ham
antispam_pipe_program_spam_arg = learn_spam
antispam_pipe_tmpdir = /var/tmp
antispam_spam = Junk
antispam_trash = trash;Trash;Deleted Items;Deleted Messages
zlib enabled:
zlib_save = gz
zlib_save_level = 9
When moving 2 or more messages from inbox to the Junk folder:
"J47 NO [CANNOT] Failed to copy to temporary file (0.000 + 0.000
secs).”. Command attempted: “J47 UID MOVE 106318:106319 Junk"
or sometimes
"J123 NO [CANNOT] Failed to read mail beginning (0.000 + 0.000
secs).”. Command attempted: “J123 UID MOVE 170789:170790 Junk"
and still have the "Cached message size smaller..." in dovecot logs.
It occurs at least when header lines of an email contains Non-ASCII
Text (rfc1342).
Batches of full ascii emails are not affected.
I can easily reproduce this from/to the Junk folder, but had
unconfirmed reports of similar errors when batch moving mails across
regular folders.

Hi,
I've got some trouble with the dovecot antispam plugin and the pipe
backend.
I'm using dovecot 2.2.18 with maildirs and zlib compression enabled.
When moving 2 or more emails at once from the Junk folder to another
one, I always have the following error : "Failed to copy to temporary
file"
In the server logs :
imap(v...@vvv.vvv): Error:
read(zlib(/data/Maildir/.test/tmp/1446974366.M123890P936.vvv)) failed:
Cached message size smaller than expected (13553 < 13562, box=test,
UID=0)
The same operation with one email at a time, on the same emails, works
as expected.
