[Dovecot] Fatal: open() failed for /var/run/dovecot/login: Permission denied
by Andy Yen 15 Mar '10

15 Mar '10

I keep getting this message when I try to start dovecot using the -F option. Fatal: open() failed for /var/run/dovecot/login: Permission denied Checking /var/run/dovecot/login folder permissions does not seem to indicate anything wrong as root has all the permissions it needs. If I am not mistaken, dovecot can run as root while in the login directory correct? When I try to start the dovecot service, it fails with the message: dovecot dead but subsys locked. Can anybody help me resolve this issue? I am running RHEL5.4. Thanks in advance.

[Dovecot] Extra Imap processes
by Dominique St-Amand 15 Mar '10

Hello fellow dovecot users! I have a question for you guys. I have a server running dovecot/exim and I allow both pop/pops and imap/imaps. When I look at the running processes, I see a lot of imap processes that look like the following: imap [user(a)domain.tld USER_IP] Sometimes, there are duplicates imap [user(a)domain.tld USER_IP] processes. I was wondering, how come those processes don't quit and stick around in the system? Should they quit after the user issued the disconnect command from its mail client? Also, is there any way to actually make them to quit or should I make a shell script that runs at a certain period of time and actually kill those processes? Thanks

[Dovecot] Status update
by Timo Sirainen 14 Mar '10

14 Mar '10

Looks like I'm pretty badly lagged behind emails in mailing list and in my INBOX. I should read and do something about maybe 150 messages. The good thing at least is that v2.0 is getting closer. Only 3 larger things left besides bug fixing: 1. config handling is too slow 2. I just noticed auth cache is only for passdb. it really should be changed to cache userdb too. 3. fts-solr should optionally use mailbox GUIDs instead of mailbox names And 2 and 3 are actually old problems..

[Dovecot] bug or feature?
by zhong ming wu 14 Mar '10

14 Mar '10

Dear List If ssl_username_from_cert = yes then setting of auth_username_chars is not respected. (It may be that anything goes in that case) Also how can I include space (0x20) in auth_username_chars if I don't use ssl_username_from_cert = yes Thanks mr.wu

[Dovecot] I need IMAP stress testing tool with SEARCH command
by Ernesto Revilla 14 Mar '10

14 Mar '10

Hi. Does anyone know of a good imap stress testing tool? And one which supports SEARCH commands? I have to compare Courier and Dovecot. I already did some tests using a modified postal/rabid package. I would be thankfully for any hints. Best regards. Erny Yaco Sistemas Spain

[Dovecot] Bug in driver-mysql.c + fix
by Alain Williams 13 Mar '10

13 Mar '10

I tried to use MySQL stored procedures from dovecot: password_query = CALL user_pass_check('%n', '%d', '%w') user_query = CALL user_info('%n', '%d') This failed with the message: User query failed: PROCEDURE imap.user_info can't return a result set in the given context The root of this problem is that mysql_real_connect() needs to be called with option CLIENT_MULTI_RESULTS and mysql_next_result() called to retrieve extra results (that will not exist in the way that we use it). I attach a patch that fixes this problem -- the patch is against dovecot-1.2.10. This works for me ... but could probably do with testing by other people. BTW: I got the same problem with exim this morning, wrote a patch that has now been accepted. The dovecot patch is similar. I am looking to use mysql procedures, there are some interesting things that can be done. Two suggestions that I have will help with this: 1) There be variable (say) %o - this be the obscured password, ie what password_query returns. 2) that dovecot look for either ''password_query'' as above, or ''password_check''. password_check would NOT return a password, but would be given %o and determine itself if the password is correct. It would return the other values (user, userdb_home, ...) and auth_result that would encode success/retry/fail (0, 1, 2 - or maybe more structured [**]) and auth_reason some human readable reason. The ''nologin'' value encodes some of this. The motivation for this is that my stored procedure will record the number of successive login failures and lock the account after 3 of them. It would also be possible to do time based restrictions & the such. Also: by passing %o the password is not sent in plain to the database server - which will increase security. I will publish my stored procedures when done. Regards [**] eg taking ideas from the HTTP codes: 200 - OK 300 5 - try again in 5 minutes 301 2 9 - try again on tuesday at 9am 400 - Login forbidden, no reason given 401 - bad username and/or password 402 - account locked administratively 403 - too many failed login attempts 500 - authentication system error The above would allow a native language version of auth_reason to be produced -- Alain Williams Linux/GNU Consultant - Mail systems, Web sites, Networking, Programmer, IT Lecturer. +44 (0) 787 668 0256 http://www.phcomp.co.uk/ Parliament Hill Computers Ltd.

[Dovecot] Plugin like zlib
by Alex Baule 13 Mar '10

13 Mar '10

Hi everyone. I rebuild a plugin, based on zlib plugin. The changes between this plugin and zlib, is the zlib stuffs is replaced by open, read, lseek, close. With "plain-text" files, its works ok. So, my file is encrypt, and the result from decrypt file is different from fread. Like zlib, i read from fread the size variable, but the value added in seek_offset and pos is the result from decrypt, and it can be dfferent from fread. Like zlib, my file size is different from email. In zlib the file is smaller than the email. In my file, the file is bigger than the email. OK, lets go to the problem now. when the email arrives in the new folder, by imap, the stat (read my file by "while (i_stream_emexis_read(stream) > 0)" like zlib) and the seek works fine....the email is readed and the final stat size is the decrypted size of my email (smaller than original file). When I receive the email, clicking in "Send/Receive", The read function is aborted because the size to read (like zlib) is negative. I put some debug in my plugin, and print some stuffs about the functions. Email decryt size = 49556 Email encrypt size = 49568 Attachements: mail-arrived, is when the email arrives, and it's ok the read. mail-receive, is when the email is received, and have the error. maillog is the /var/log/mail The bigger difference from zlib is the i_stream_zlib_read part.... do { ret = read(zstream->fd ,crypttext, size); fprintf(zstream->debug,"DENTRO DA READ RET = %d -- ERRNO = %d -- STR = |%s|\n", ret, errno, strerror(errno)); if(ret > 0){ EVP_DecryptUpdate(&ctx, plaintext, &plain_len, crypttext, ret); memcpy(stream->w_buffer + stream->pos , plaintext, plain_len); bzero (plaintext, DEFAULT_MAX_BUFFER_SIZE); EVP_DecryptFinal(&ctx, plaintext, &plain_len_final); memcpy(stream->w_buffer + stream->pos + plain_len , plaintext, plain_len_final); } } while (ret < 0 && errno == EINTR && stream->istream.blocking); *retc *= plain_len + plain_len_final; if (ret == 0 ) { /* EOF */ stream->istream.eof = TRUE; return -1; } if (ret < 0) { if (errno == EAGAIN) { i_assert(!stream->istream.blocking); ret = 0; // } else { // i_assert(errno != 0); // stream->istream.stream_errno = errno; // return -1; } } fprintf(zstream->debug,"READ RET = %d -- ERRNO = %d -- STR = |%s|\n", ret, errno, strerror(errno)); fprintf(zstream->debug,"stream->pos = %d -- zstream->seek_offset = %d\n", stream->pos, zstream->seek_offset); zstream->seek_offset += *retc*; stream->pos += *retc*; i_assert(ret > 0); fprintf(zstream->debug,"READ RET DECRYPT = %d -- stream->pos = %d -- zstream->seek_offset = %d\n", ret, stream->pos, zstream->seek_offset); fprintf(zstream->debug,"********************** FINISH READ *********************\n"); fflush(zstream->debug); return *retc;* The* retc* is the result from decrypt. In mail-receive file (line 38), there is the error, at some point along the read/send email, the stream->pos (its returned by i_stream_compress, with stream->pos -= stream->skip) is changed out from context and the size to read is negative, but i don't understand why. Someone can help me find out what happens ?
