[Dovecot] Limiting number of IMAP connections per user
by Simon L Jackson 22 Sep '06

22 Sep '06

Hi, Is there a way of limiting the number of IMAP connections (i.e. processes) per user? Despite asking users to set their email client settings to limit themselves to 2 connections, some still have this set to 10 or more.

[Dovecot] Incorrect GSSAPI Service Name for POP3
by Tim Steiner 22 Sep '06

22 Sep '06

In pop3-login/client-authenticate.c, when sasl_server_auth_begin() is called, it does so with the service name of "POP3". GSSAPI uses this service name when obtaining its service credentials. The problem is that according to http://www.iana.org/assignments/gssapi-service-names , the service name should instead be simply "pop". This causes GSSAPI authentication to fail when used with a POP3 account. I have created a small patch that corrects this problem for GSSAPI only, as I do not know if other mechanisms are affected by this. --Tim Steiner ----------------------------START PATCH---------------------------- diff -ruN dovecot-1.0.beta8/src/auth/mech-gssapi.c dovecot-1.0.beta8.new/src/auth/mech-gssapi.c --- dovecot-1.0.beta8/src/auth/mech-gssapi.c 2006-09-18 17:35:02.000000000 -0500 +++ dovecot-1.0.beta8.new/src/auth/mech-gssapi.c 2006-09-18 17:37:46.000000000 -0500 @@ -101,7 +101,11 @@ gss_name_t gss_principal; principal_name = t_str_new(128); - str_append(principal_name, t_str_lcase(request->service)); + if(strcmp(request->service, "POP3") == 0) { + str_append(principal_name, "pop"); + } else { + str_append(principal_name, t_str_lcase(request->service)); + } str_append_c(principal_name, '@'); str_append(principal_name, my_hostname); -----------------------------END PATCH-----------------------------

Is it possible to force a subscription to an IMAP folder? So that a user by default is subscribed to folder <foo> and cannot unsubscribe. -- Vegard Svanberg <vegard(a)svanberg.no> [*Takapa@IRC (EFnet)]

Currently 17 servers doing just filtering. These run Postfix, SpamAssassin, Policyd, ClamAV. > -Have you ever used perdition and if so, how does dovecot as a proxy > compare to that? Yes. Perdition requires a process per connection though, so it does not scale well. With Dovecot's proxy (and also the nginx proxy, http://sysoev.ru/en/) individual processes can handle multiple connections, and takes advantage of epoll for network events which is ideal for handling large numbers of idle IMAP connections. With Perdition we'd run at 2000 connections per server, with Dovecot we haven't it a peak yet, but expect to peak at around 15,000 - 25,000 connections per proxy server. Obviously the bigger the box, the more connections it can handle. > -Do you mind me asking these questions? Nope. Ask away. If I can't answer it I'll tell you. Bill

[Dovecot] Running just part of dovecot
by Marshal Newrock 22 Sep '06

22 Sep '06

I'm currently setting up a large mail system, with different services split out onto different machines. What I want is this: machine1: dovecot smtp auth, no pop/imap machine2: dovecot lda, no pop/imap machine3: pop/imap, nothing else machine3 is obviously not the issue. Is there a way to run machine1 and machine2 with just their respective services, but no pop/imap? -- Marshal Newrock Ideal Solution, LLC - http://www.idealso.com

[Dovecot] DSpam plugin
by Michael Blinn 22 Sep '06

22 Sep '06

I'm trying to set up Johannes's DSpam plugin for dovecot. I've compiled rc2 and the plugin, and have things installed OK. I have a X-DSPAM-Signature in my message that is delivered to Inbox. Whenever I try to move this to my spam folder (I changed source to say 'Spam' instead of 'SPAM'), my client (Thunderbird) pops up 'The current command did not succeed. The mail server responded: dspam failed.' I've set '#define DEBUG 1' in the plugin and see this in my 'messages' log. Sep 20 09:39:03 ltsp imap: /usr/local/bin/dspam --source=error --stdout --class=spam --signature=45113fe931161804284693 '/usr/local/bin/dspam' is the location of my dspam binary. Occasionally, though not every time I move a message, I see this in my 'messages' log. Sep 20 09:38:34 ltsp kernel: imap[3656]: segfault at 0000000000102490 rip 00002aaaaaafc589 rsp 00007fffabda5400 error 4 Sep 20 09:38:34 ltsp kernel: imap[3653]: segfault at 0000000000102490 rip 00002aaaaaafc589 rsp 00007fff31e814e0 error 4" I also see this, though the login is successful: Sep 20 09:43:44 ltsp dovecot-auth: pam_ldap: could not open secret file /etc/ldap.secret (No such file or directory) Can anyone point me in a direction?
