Hi Im using Dovecot 1.0.10 and everything seems work ok except one client He is accessing his mailbox using iPhone There are several custom folders created and mail is directed to them using procmail The problem is iPhone mail app only sees changes in INBOX and when new mail arrives to other folders it will not see it unlers user accesses this particular folder Is there some kind of workaround for this? Im quite sure its iPhones fault as all other email clients are workin perfectly fine.

[Dovecot] Mail delivery to subfolders via address extension, and prefered lda method
by Micha Krause 27 Feb '12

27 Feb '12

Hi, I want to deliver mails directly to subfolders, based on address extensions. Example: Emails sent to: micha+test(a)example.com Should be stored into user micha, folder INBOX.test I was able to reproduce this with exim and dovecot-lda: command = /usr/lib/dovecot/dovecot-lda -e -m "INBOX.${substr_1:$local_part_suffix}" But I was wondering if I could do this within dovecot, which would enable me to use LMTP instead of dovecot-lda. Which brings me to my second question: Which method is "better" for dovecot, lda or LMTP? Micha Krause

[Dovecot] Virtual Folders
by jacob＠alltechservices-ia.com 27 Feb '12

27 Feb '12

Hello, I am trying to get virtual folders to work properly, and I can't seem to. I will be as detailed as possible to remove confusion. Thank you in advance. Goal: Essentially, a gmail clone, but one that I can make work on cPanel hosts with roundcube and squirrel mail, etc. By default, cpanel creates user mail dir structure of (maildir++) inbox, drafts, sent, junk, and trash (with no dovecot specific files until first login) I would like to replace all those folders with virtual representations with more capabilities. I would like to achieve the conversation view that gmail has pulled off so well. cPanel, stock, generates the following dovecot -n: (i am still not sure how it negotiates mail_location yet) # 1.2.17: /etc/dovecot.conf # OS: Linux 2.6.18-238.5.1.el5xen x86_64 CentOS release 5.7 (Final) ssl_cert_file: /etc/dovecot/ssl/dovecot.crt ssl_key_file: /etc/dovecot/ssl/dovecot.key ssl_cipher_list: ALL:!ADH:RC4+RSA:+HIGH:+MEDIUM:-LOW:-SSLv2:-EXP login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login login_process_per_connection: no login_processes_count: 10 login_max_processes_count: 100 login_max_connections: 500 mail_max_userip_connections: 200 maildir_copy_preserve_filename: yes mail_plugins: quota imap_quota namespace: type: private prefix: INBOX. inbox: yes list: yes subscriptions: yes lda: postmaster_address: postmaster(a)example.com auth default: mechanisms: plain login cache_size: 2048 username_chars: abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789!#$-=?^_{}~./@+% passdb: driver: checkpassword args: /usr/local/cpanel/bin/dovecot-auth userdb: driver: prefetch socket: type: listen client: path: /var/run/dovecot/auth-client mode: 438 plugin: quota: maildir quota_rule: Trash:ignore I started a test box with Debian running the same version of dovecot (1.2.x) and on that system I run into problems every time I make a virtual folder a root folder. I assume it is trying to look up a normal folder instead of the virtual ones and I am confusing it. So I came here because it would be really really neat if I could pull this off. Again, thank you in advance. -cornfeed

[Dovecot] Dovecot 2.1 with custom OpenSSL fails to build
by Andreas M. Kirchwitz 27 Feb '12

27 Feb '12

Hello Dovecot users! There seems to be a new dependency in some modules (eg, lib-storage, libdovecot-lda, libdovecot-ssl) on OpenSSL. In Dovecot 2.0, those modules didn't require OpenSSL, but 2.1 does. For the linking process the path to the OpenSSL library isn't specified properly (SSL_LIBS). Dovecot fails to build if OpenSSL is in a non-standard path. (Haven't checked if SSL_CFLAGS isn't properly used as well.) Example for lib-storage: env SSL_CFLAGS="-I/usr/local/ssl/include" SSL_LIBS="-L/usr/local/ssl/lib -Wl,-R/usr/local/ssl/lib -lcrypto -lssl" ./configure --prefix=/usr/local/${DOVECOTVER} --with-ssl=openssl --with-ssldir=/usr/local/${DOVECOTVER}/etc/dovecot/certs make gcc -DHAVE_CONFIG_H -I. -I../.. -I../../src/lib -I../../src/lib-master -I../../src/lib-settings -I../../src/lib-mail -I../../src/lib-storage -DPKG_RUNDIR=\""/usr/local/Dovecot-2.1.1/var/run/dovecot"\" -std=gnu99 -g -O2 -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -fno-builtin-strftime -Wstrict-aliasing=2 -I/usr/local/ssl/include -MT master-connection.o -MD -MP -MF .deps/master-connection.Tpo -c -o master-connection.o master-connection.c mv -f .deps/master-connection.Tpo .deps/master-connection.Po /bin/sh ../../libtool --tag=CC --mode=link gcc -std=gnu99 -g -O2 -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -fno-builtin-strftime -Wstrict-aliasing=2 -I/usr/local/ssl/include -no-undefined -Wl,--as-needed -o indexer-worker indexer-worker.o indexer-worker-settings.o master-connection.o ../../src/lib-storage/libdovecot-storage.la ../../src/lib-dovecot/libdovecot.la -export-dynamic -ldl -lrt libtool: link: gcc -std=gnu99 -g -O2 -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -fno-builtin-strftime -Wstrict-aliasing=2 -I/usr/local/ssl/include -Wl,--as-needed -o .libs/indexer-worker indexer-worker.o indexer-worker-settings.o master-connection.o -Wl,--export-dynamic ../../src/lib-storage/.libs/libdovecot-storage.so ../../src/lib-dovecot/.libs/libdovecot.so -ldl -lrt -Wl,-rpath -Wl,/usr/local/Dovecot-2.1.1/lib/dovecot /usr/bin/ld: warning: libcrypto.so.1.0.0, needed by ../../src/lib-storage/.libs/libdovecot-storage.so, not found (try using -rpath or -rpath-link) /usr/bin/ld: warning: libssl.so.1.0.0, needed by ../../src/lib-storage/.libs/libdovecot-storage.so, not found (try using -rpath or -rpath-link) ../../src/lib-storage/.libs/libdovecot-storage.so: undefined reference to `OBJ_txt2nid' ../../src/lib-storage/.libs/libdovecot-storage.so: undefined reference to `SSL_set_ex_data' [...] # ldd src/lib*/.libs/*.so src/lib-dovecot/.libs/libdovecot.so: linux-gate.so.1 => (0x00979000) libdl.so.2 => /lib/libdl.so.2 (0x00c31000) librt.so.1 => /lib/librt.so.1 (0x009ed000) libc.so.6 => /lib/libc.so.6 (0x0054d000) /lib/ld-linux.so.2 (0x00c12000) libpthread.so.0 => /lib/libpthread.so.0 (0x008f4000) src/lib-lda/.libs/libdovecot-lda.so: linux-gate.so.1 => (0x0096d000) libdovecot-storage.so.0 => /usr/local/src/dovecot-2.1.1/src/lib-storage/.libs/libdovecot-storage.so.0 (0x00ae4000) libdovecot.so.0 => /usr/local/src/dovecot-2.1.1/src/lib-dovecot/.libs/libdovecot.so.0 (0x00110000) librt.so.1 => /lib/librt.so.1 (0x00189000) libc.so.6 => /lib/libc.so.6 (0x00192000) libcrypto.so.1.0.0 => not found libssl.so.1.0.0 => not found libdl.so.2 => /lib/libdl.so.2 (0x0031c000) libpthread.so.0 => /lib/libpthread.so.0 (0x00ebc000) /lib/ld-linux.so.2 (0x003f8000) src/lib-sql/.libs/libdovecot-sql.so: linux-gate.so.1 => (0x00a95000) libdovecot.so.0 => /usr/local/src/dovecot-2.1.1/src/lib-dovecot/.libs/libdovecot.so.0 (0x002b6000) libdl.so.2 => /lib/libdl.so.2 (0x00ab8000) librt.so.1 => /lib/librt.so.1 (0x0072a000) libc.so.6 => /lib/libc.so.6 (0x008f7000) /lib/ld-linux.so.2 (0x00ebd000) libpthread.so.0 => /lib/libpthread.so.0 (0x00619000) src/lib-ssl-iostream/.libs/libdovecot-ssl.so: linux-gate.so.1 => (0x00da6000) libcrypto.so.1.0.0 => not found libssl.so.1.0.0 => not found libdl.so.2 => /lib/libdl.so.2 (0x00df0000) librt.so.1 => /lib/librt.so.1 (0x00112000) libc.so.6 => /lib/libc.so.6 (0x00b5e000) /lib/ld-linux.so.2 (0x00e76000) libpthread.so.0 => /lib/libpthread.so.0 (0x005a6000) src/lib-storage/.libs/libdovecot-storage.so: linux-gate.so.1 => (0x006ed000) libcrypto.so.1.0.0 => not found libssl.so.1.0.0 => not found libdovecot.so.0 => /usr/local/src/dovecot-2.1.1/src/lib-dovecot/.libs/libdovecot.so.0 (0x00c66000) libdl.so.2 => /lib/libdl.so.2 (0x00491000) librt.so.1 => /lib/librt.so.1 (0x00be2000) libc.so.6 => /lib/libc.so.6 (0x00110000) /lib/ld-linux.so.2 (0x0036b000) libpthread.so.0 => /lib/libpthread.so.0 (0x0029a000) Without SSL_CFLAGS and SSL_LIBS but just PKG_CONFIG_PATH, it also won't work.

[Dovecot] Dovecot altmove questions
by Maria Arrea 27 Feb '12

27 Feb '12

Hello We are using Dovecot 2.0.17 with mdbox+zlib and we are evaluating alternative storage. These are the relevant settings mdbox_rotate_interval = 1d mdbox_rotate_size=60m [...] zlib_save_level = 9 # 1..9 zlib_save = gz # or bz2 [...] zlib plugin enabled in dovecot-lda These are my questions: 1º General mdbox question. We are happy usings zlib_save, but we would like to try bzip2 compression. Can we change zlib to bzlib without problems? In other words, can we mix & match gzipped and bzipped messages in the same mdbox file ? 2º With doveadm altmove we can move messages matching a pattern to alternate storage. I have read an older post in this mailing list about passing specific mdbox options to doveadm altmove. Should be a good idea to have a "main" mdbox area with zlib 9 and mdbox_rotate=1d and mdox_rotate_size=60m and an "alternate area" with bzip9, mdbox_rotate=1 week and rotate_size > 60 MB? In the alternate area should only be "old" mail (1 year older). 3º We have separate raids for indexes (raid 1+0) and mdboxes (raid 5). We have almost 3 TB of gzipped mdboxes, and our backup (bacula) is taking almost 16 hours to make a full backup. Our main problem is that indexes are backupd hours before mdboxes, and that bring us some inconsistencies. What is the "right" way of backing up for separate indexes and mdboxes? Thank you for your support. Maria

[Dovecot] IMAP-proxy or not with sogo webmail and dovecot backend
by Jan-Frode Myklebust 27 Feb '12

27 Feb '12

We've been collecting some stats to see what kind of benefits UP/SquirrelMail's IMAP Proxy in for our SOGo webmail users. Dovecot is running in High-performance mode http://wiki2.dovecot.org/LoginProcess with authentication caching http://wiki2.dovecot.org/Authentication/Caching During the weekend two servers (webmail3 and webmail4) has been running with local imapproxy and two servers without (webmail1 and webmail2).

We haven't dug deeper yet, but the error is being thrown from the method io_loop_handle_add in ioloop-epoll.c http://hg.dovecot.org/dovecot-2.0/file/aa8dfa085a99/src/lib/ioloop-epoll.c Thanks Doug
