dict host param and fqdn
Hi, I would like to use a fqdn instead of an IP address as redis host quota_clone_dict = redis:host=redis.host.name:port=6379 But only ip adresses are supported Error: quota_clone_dict: Failed to initialize 'redis:host=redis.host.name:port=6379': dict redis: Invalid IP: redis.host.name Why is name resolution not implemented here ? Is it for performance considerations ? Stéphane
Re: antispam plugin pipe backend error when moving multiple emails
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.

antispam plugin pipe backend error when moving multiple emails
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.

We do not have dspam crashes caused per email contents, they always are system( disk errors, oom kill,…) , clamav or database issues.

You're right about my mistake using pipes, but there may be some cases where validating input make sense.

LDA input validation
Hi, I'm using qmail + dspam + dovecot-lda. A typical .qmail file : | /usr/bin/dspam --client --deliver=stdout --user "$EXT@$USER" | /usr/bin/preline -f /usr/lib/dovecot/dovecot-lda -d "$EXT@$USER" -a "$EXT@$USER" -m "$EXT2" When dspam segfault or is killed, preline receive an empty content and only pass to dovecot-lda two headers ( Return-Path and Delivered-To ). Then dovecot-lda delivers successfully and the original message contents are lost. Should dovecot-lda returns an error in such conditions ( invalid contents ) ? Qmail will keep it in the queue and retry delivery later. Stéphane

[Dovecot] lda deliver + vpopmail
Hi all,
I'm enjoying using dovecot deliver with qmail+vpopmail+dspam.
It works mostly fine, I like the indexing and sieve features with dovecot
deliver.
I would like to get more details on trouble, the log entry is just :
"
2009-11-18_20:38:55.64778 delivery 50833: deferral:
"
As you see, there no reason for the deferral. How can I make deliver more
verbose ?
I also have a vpopmail alias issue.
Because some domains (sadly) needs a catchall, and to keep using the useful
vpopmail alias features, I'm using the following ugly script :
"
#!/bin/sh
email=`/usr/sbin/valias -- $1 2>/dev/null | cut -d" " -f3`
if [ -z "$email" ];then
email=$1
t=`/usr/sbin/vuserinfo -n -- $1 2>&1>/dev/null`
t=$?
if [ "$t" == "255" ];then
domain=`echo "${1}" | cut -d'@' -f 2`
dir=`/usr/sbin/vdominfo -d $domain 2> /dev/null| head -1`
email=`cat ${dir}/.qmail-default | head -1 | awk -F# '{ print
$2 }'`
if [ "$email" == "bounce-no-mailbox" ];then
email=$1
fi
fi
fi
echo $email
"
my .qmail-default file contains :
"
#bounce-no-mailbox
| /usr/bin/dspam --client --deliver=innocent,spam --user `/usr/sbin/vrealemails
$...@$user` --stdout | /usr/bin/preline -f /usr/lib/dovecot/deliver -d
`/usr/sbin/vrealemails $...@$user`
"
or if using a catchall :
"
#catch...@domain.com
| /usr/bin/dspam --client --deliver=innocent,spam --user `/usr/sbin/vrealemails
$...@$user` --stdout | /usr/bin/preline -f /usr/lib/dovecot/deliver -d
`/usr/sbin/vrealemails $...@$user`
"
I don't like this way for design and security reasons and would prefer a more
consistent approach. The vpopmail alias lookup should be made internally by
deliver, and unlike my script, handle one to many aliasing.
The catchall feature is (sadly) also needed, my implementation is ugly, in
practice it works, but is limited as the catchall address must be on the same
host.
I'm thinking about adding a specific option to the deliver command line, but
I'm not sure that's the better way to do it.
Help needed please
Stéphane

[Dovecot] lda catchall

If I want to bounce, a first line like "# bounce-no-mailbox" in the .qmail file works, without this line, emails to unknown addresses are deferred and stay in the queue, because they are deliverable for qmail, but not for dovecot lda.
