[Dovecot] istream_read like zlib, but without zlib
by Alex Baule 31 Aug '10

31 Aug '10

Hy Timo ! I Made some modification in stream_read in zlib. I remove all zlib part, because i don't need this, but i need to read a istream to change it. Well, i create a size_t called supersize, with is a substitute for stream->zs.avail_in. The trouble is, my debug file have a lot of "READ Plugin\n", and i think it's because my read becomes a loop, i think it's because i don't know to identify the EOF from the istream. you can help me to identify the EOF and set it ? Tks .!!! static ssize_t i_stream_emx_read(struct istream_private *stream) { struct emx_istream *emxstream = (struct emx_istream *)stream; const unsigned char *data; uoff_t high_offset; size_t size; int ret; fprintf(emxstream->debug,"READ Plugin\n"); fflush(emxstream->debug); high_offset = stream->istream.v_offset + (stream->pos - stream->skip); if (emxstream->eof_offset == high_offset) { i_assert(emxstream->high_pos == 0); stream->istream.eof = TRUE; return -1; } if (stream->pos < emxstream->high_pos) { /* we're here because we seeked back within the read buffer. */ ret = emxstream->high_pos - stream->pos; stream->pos = emxstream->high_pos; emxstream->high_pos = 0; return ret; } emxstream->high_pos = 0; if (stream->pos + CHUNK_SIZE > stream->buffer_size) { /* try to keep at least CHUNK_SIZE available */ if (!emxstream->marked && stream->skip > 0) { /* don't try to keep anything cached if we don't have a seek mark. */ i_stream_compress(stream); } if (stream->max_buffer_size == 0 || stream->buffer_size < stream->max_buffer_size) i_stream_grow_buffer(stream, CHUNK_SIZE); if (stream->pos == stream->buffer_size) { if (stream->skip > 0) { /* lose our buffer cache */ i_stream_compress(stream); } if (stream->pos == stream->buffer_size) return -2; /* buffer full */ } } if(emxstream->supersize == 0){ /* need to read more data. try to read a full CHUNK_SIZE */ i_stream_skip(stream->parent, emxstream->prev_size); if (i_stream_read_data(stream->parent, &data, &size, CHUNK_SIZE-1) == -1 && size == 0) { if (stream->parent->stream_errno != 0) { stream->istream.stream_errno = stream->parent->stream_errno; } else { i_assert(stream->parent->eof); stream->istream.stream_errno = EPIPE; } return -1; } emxstream->prev_size = size; if (size == 0) { /* no more input */ stream->istream.eof = TRUE; i_assert(!stream->istream.blocking); return 0; } fprintf(emxstream->debug,"READ =|%s|= Plugin\n",data); fflush(emxstream->debug); memcpy(stream->w_buffer + stream->pos, data,size); emxstream->supersize = size; } size = stream->buffer_size - stream->pos; stream->pos += size; if(stream->istream.eof == TRUE){ emxstream->eof_offset = stream->istream.v_offset + stream->pos; i_stream_skip(stream->parent, emxstream->prev_size - emxstream->supersize); emxstream->supersize = 0; emxstream->prev_size = 0; } if (size == 0) { /* read more input */ return i_stream_emx_read(stream); } return size; }

You could replace the imap or pop3 helper program with a wrapper that first sends the fetchmail daemon a wakeup signal, waits a few secs and then calls the original.

[Dovecot] Combining ManageSieve with hand-written scripts
by Jason Bleazard 30 Aug '10

30 Aug '10

Hi, new to Dovecot, forgive me if I'm missing something basic... I'm trying to figure out if there's a way to use a couple of custom rules alongside ManageSieve. Most of the time I like the ManageSieve interface in Roundcube, but there's one rule that I can't get it to do the way I want (it's a notify rule, and I don't like the way Roundcube constructs the notify). I figured out how to write it by hand, but of course I can't put my own rules in Roundcube's file or it gets really confused. I tried adding an include to the generated file, but Roundcube politely removes it for me the next time I use the rule editor. (Squirrelmail doesn't seem to be any better in this regard.) I thought I could do something like sieve_before = ~/sieve/custom.sieve but that doesn't seem to work. I couldn't even see any evidence in the log that it attempted to look at that file. Apparently sieve_before isn't meant to work on a per-user basis. If I do a global sieve_before, can I have it "include :personal"? If so, what's going to happen with the script compilation? From what I understand, it can't be compiled globally, since each user has a different custom rule set. Am I trying to do the impossible here? Thanks for any ideas, Jason Bleazard

[Dovecot] Different IPs should use different ssl-certs/keys
by Peer Heinlein 30 Aug '10

30 Aug '10

I don't understand how to use multiple keys/certs on different IPs without SNI. http://wiki2.dovecot.org/SSL/DovecotConfiguration explains how to use different keys for different protocols like POP3 and IMAP. But how to bind those keys/ on IPs/Ports? Looks like it is not possible to use ssl_cert inside service { inet_listener {} } Is it still necessary to run multiple instances like it was in Dovecot 1.2.x?

Hi! Is it possible to configure Dovecot so that it drops privileges for dict process? Currently this process is running as root. (At least on my system with Dovecot 1.2.) Best regards Mike

Re: [Dovecot] doveadm expunge -A mailbox Trash savedbefore 30d
by Jerrale G 30 Aug '10

Could you explain the iterate_query in any kind of sql. I'm guessing to just use the query, correctly, that's failing as iterate_query= and put it in the service auth file which includes password_query and user_query. then, I'm guessing to add something like: iteratedb { driver = sql args = /path/to/sql.conf } The wiki2 only says: "When the SQL userdb module is used make sure that the iterate_query setting in /etc/dovecot/dovecot-sql.conf.ext matches your database layout." it should give an example query. I don't know if its wanting to list the fields or the contents of a field. Thanks, Jerrale G Jerrale G. SC Senior Admin

[Dovecot] Can't get dovecot to see email folders
by Blaster 30 Aug '10

30 Aug '10

So I'm very frustrated, I've spent the better part of a day trying to get dovecot 2.0.1 working...Most of the documentation on the Wiki seems to think you are running an older version and therefore very little of it applies. I'm running 2.0.1 on OpenSolaris. I seem to have 2 remaining issues: 1) Dovecot is not able to determine the home directory 2) IMAP clients can not get to the mail folder directory. One client is reporting that it can't open it in read only mode. 3) I tried to get raw logging working, but apparently I couldn't because of #1. The architecture of Dovecot makes it difficult to transition from another IMAP server. If I force the MBOX to be /home/%u/mail, all of my clients think the folders are in /home/%u/mail/mail. If I set mbox location to /home/%u, then dovecot tries to create .subscription and .imap files/directories in the users home dir which it doesn't have permission to do. It would be nice if you could configure Dovecot in such a way as to make transition easier, such as the ability to strip off a duplicate trailing path, ie /home/%u/mail/mail becomes /home/%u/mail....Otherwise this necessitates visiting countless IMAP clients for reconfiguration... Here is my config file: /opt/sbin/dovecot -n # 2.0.1: /opt/etc/dovecot/dovecot.conf # OS: SunOS 5.11 i86pc base_dir = /var/run/dovecot/ mail_debug = yes mail_gid = mail mail_location = mbox:/home/%u/mail:INBOX=/var/mail/%u mail_privileged_group = mail mail_uid = dovecot passdb { driver = pam } plugin { home = /home/%u } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { address = * port = 993 } } service pop3-login { inet_listener pop3 { address = * port = 0 } inet_listener pop3s { address = * port = 0 } } ssl_cert = </usr/local/ssl/certs/dovecot.pem ssl_key = </usr/local/ssl/private/dovecot.pem gremlin [/opt/bin] # gremlin [/opt/bin] #
