[Dovecot] Dovecot Proxy
by Michel Bulgado 14 Aug '09

14 Aug '09

Hello I have installed Dovecot as a POP3 server, IMAP on my internal network, the authentication against Windows Active Directory. I would like to know how to setup a second server dovecot as my proxy server for external users outside the network, in another segment of different IP addresses, or at least define which mailboxes will be stored on another server to be accessible to both servers. I have reviewed the document on the wiki site, but I said that is only possible with mysql authentication, but as I said the road where the messages are stored, it is possible for NFS? Thanks Michel

[Dovecot] Migrating Emails from 1.0.15 to 1.2.2
by Mario Antonio 14 Aug '09

14 Aug '09

I need to copy some email storage from a Dovecot Server running 1.0.15 into another Dovecot Server running 1.2.2. I know that I can use imapsync (perhaps this is the proper way) But I was just wondering, if I can just run Rsync to do that transfer: Will I run against some incompatibility formats between these two versions? M.A.

[Dovecot] map->hdr.record_size <= tview->record_size
by Edgar Fuß 14 Aug '09

This is 1.2.3, but there are also two older dovecots (with different machine architecture) sharing the mail store: dovecot: IMAP(xxx): Panic: file mail-index-transaction-view.c: line 106 (tview_apply_flag_updates): assertion failed: (map->hdr.record_size <= tview->record_size)

[Dovecot] QUOTA not appearing in CAPA
by Tim Traver 14 Aug '09

14 Aug '09

Hi, ok, I've compiled it a few times, and made sure all of my settings are correct, but the QUOTA is not appearing in the opening CAPA that comes with the greeting. I have it configured in the dovecot.conf like so: protocol imap { mail_plugins = quota imap_quota } and I can see when turning debugging on that the following is spit out when starting : Starting DovecotILoading modules from directory: /usr/local/lib/dovecot/imap IModule loaded: /usr/local/lib/dovecot/imap/lib10_quota_plugin.so IModule loaded: /usr/local/lib/dovecot/imap/lib11_imap_quota_plugin.so IEffective uid=65534, gid=65534, home=/tmp IQuota root: name= backend=maildir args= IEffective uid=65534, gid=65534, home=/tmp and then I see the following in the dovecot logs : Aug 10 17:35:10 IMAP(xxxxx(a)simplenet.com): Info: Module loaded: /usr/local/lib/dovecot/imap/lib10_quota_plugin.so Aug 10 17:35:10 IMAP(xxxxx(a)simplenet.com): Info: Module loaded: /usr/local/lib/dovecot/imap/lib11_imap_quota_plugin.so when I log into the IMAP port, I get the following greeting : * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE STARTTLS AUTH=PLAIN AUTH=LOGIN] Dovecot ready. So it seems there is no QUOTA support for the IMAP server to query for the quota file... can someone help me as to a direction to go here??? The reason I need it is because I believe the web client relies on the QUOTA being in the CAPA in order to show it... Thanks, Tim.

[Dovecot] Proxying external IMAP servers
by Daniel L. Miller 14 Aug '09

14 Aug '09

For those admins who, for whatever ill-advised reason, need to allow users access to external IMAP servers - like AOL - is there a benefit to using Dovecot as a proxy instead of simply having the clients access the external servers directly? -- Daniel

[Dovecot] More effective mailbox fetching over high RTT link
by Andrzej Adam Filip 13 Aug '09

13 Aug '09

Could you offer some suggestion how to fetch mailbox content over high RTT link (with negligible packet loss)? Currently I use IMAP+IDLE *but* it fails to use full available bandwidth due to high RTT and "send command wait for response" nature of POP3 and IMAP4 protocols. -- [pl>en: Andrew] Andrzej Adam Filip : anfi(a)onet.eu Learning without thought is labor lost; thought without learning is perilous. -- Confucius

[Dovecot] sieve: variable extension?
by Lev Serebryakov 13 Aug '09

13 Aug '09

Hello, Dovecot. Does dovecot sieve supports variable extension (rfc5229)? It is very useful for users with large amount of mailing lists, as it allows to write only one rule for all lists (filtering by List-Id). If it is not supported, is here any plans to support it? I can try to implement it, but I don't want to duplicate work, if somebody has this extension in pipeline. -- // Black Lion AKA Lev Serebryakov <lev(a)serebryakov.spb.ru>

[Dovecot] Tilde expansion in ManageSieve for dovecot-1.1.
by Stephen O'Dor 13 Aug '09

13 Aug '09

Greetings all, I'll skip the details of the setup, except to say that it has a non-standard (and non-templateable) home directory path for virtual users. Ran into the following problem when a debian (possibly from backports) packaged dovecot-1.1.2 was upgraded to a dovecot-1.1.13-2~bpo50+1 (definately from backports): sieve-storage: root directory specified by mail data does not exist: ~/Maildir After some analysis, it would appear that ManageSieve (looks like 0.10.4 is included in the debian backports) doesn't do the tilde expansion before doing a stat test to see if the ~/Maildir exists. Here's a quick diff of the change I made to make it work: sodor@madawg:~/tmp/deb-dove/dovecot-1.1-managesieve-0.10.4/src/lib-sievestorage$ diff sieve-storage.c ../../../sieve-storage.c 73c73 < const char *root_dir, *dir, *p, *d; --- > const char *root_dir, *dir, *p, *d, *home; 127a128,133 > /* expand tilde in root so that the stat below works */ > home = getenv("HOME"); > if (home != NULL && *home != '\0') { > root_dir = home_expand_tilde( root_dir, home ); > } > I'm not sure if this was the best way to fix this (or if this is even a bug, I might just have a crazy setup). Thanks, -Steve
