hi, the virtusers featute is nice, can you give me some pointers about how and where to change code (hints, style, policies if any) to add the possibility to get this information from LDAP? The situation is our imap server does the auth from LDAP and all the required info can be looked up from the directory (and this is the only place where the information is stored). Without this a new user get a foo(a)127.0.0.1 from-address and there are multiple domains so i can't simply hard-wire one. i did a quick mock-up to prototype the ldap query, and it works, now it just need to be integrated into RDC :) best, Peter _______________________________________________ List info: http://lists.roundcube.net/dev/

[Fwd: Re: [RCU] any info on performance on large sites?]
by Dennis Ortsen 10 Apr '08

Hi Jami, Charles replied to me about your answer on the dev list. I must have missed your answer. My only reference point is what we currently have on servers and applications. Which are one backend server (dual CPU, 4 GB memory) with Cyrus and the mailboxes (maildir style) and one frontend server (dual CPU, 1GB memory) with IMP 3.1. This setup performs really good. We are planning a few upgrades. First we will upgrade the backend to a quad core CPU with 8 GB RAM and storage will now not be located on local disks but on a SAN. We expect that the new backend will perform awesome with these specs. After the upgrade, we plan to enlarge the mailboxes. The current quota is 25 MB per mailbox. We're thinking about 1 GB per mailbox (no problem with our SAN). This increase should not affect backend performance. After the backend upgrade, we'd like to upgrade the front end with a new webmail client that needs less change in code to integrate. (IMP needs a lot more tweaking than RC). I've read several posts about bad performance with RC on large mailboxes (over 2000 mails in one folder) and with a large folder list. Bottomline is that RC performs well when you have a small mailbox with not too much emails (about 100). If we increase the size of the mailboxes, that would also increase the time needed for the webmail client to present the mailbox list (with seen/unseen messages) and the contents. What I'm interested in is: - how much mailboxes does RC serve at your Campus? - how much simultaneous IMAP connections do you usually see (peak), with the use of an imap proxy (we use that as well)? - how is the server setup? is that similar to ours? - have you used any form of caching or load balancing with RC (2 front end servers, MySQL message caching feature of RC?)? - which version of RC are you using at the moment? The RC2 or the stable version? I hope you can help me with some info. Thanks in advance, Br. Dennis -------- Original Message -------- Subject: Re: [RCU] any info on performance on large sites?

format=flowed
by Aleksander Machniak 10 Apr '08

10 Apr '08

In rcmail_print_body() we have: if ($part->ctype_parameters['format'] != 'flowed') $body = wordwrap(trim($body), 80); I'm not shure that we should wrap lines for displaying messages, maybe do this only when sending (composing) them? I have a mail without format definition in header and Thunderbird didn't wrap the lines. Roundcube do wrapping and output is broken. I think, when displaying a message we should have something like that if( format == flowed) rewrap lines according to rfc2646 or do nothing elseif (wrap_new_mail_on_display_option == true) wrap lines else do nothing -- Aleksander 'A.L.E.C' Machniak http://alec.pl gg:2275252 LAN Management System Developer http://lms.alec.pl _______________________________________________ List info: http://lists.roundcube.net/dev/

performance
by A.L.E.C 09 Apr '08

Clicking on message generate two requests: "GET /?_task=mail&_action=preview&_uid=414&_mbox=Spam&_framed=1 HTTP/1.1" 304 26 "POST /?_task=mail&_action=mark HTTP/1.1" 200 205 and one login to imap server for each. I think such "related actions" should be done with one imap connection and one request. -- Aleksander 'A.L.E.C' Machniak http://alec.pl gg:2275252 LAN Management System Developer http://lms.org.pl _______________________________________________ List info: http://lists.roundcube.net/dev/

I glanced over his shoulder when he used my home computer to check his e-mail, and lo and behold I saw RoundCube in an iframe. I don't know if RC is rolled out to all of the umaine.edu campuses, or just the one he attends. When I asked him about the web mail system, he said it was a recent switch. I'm not sure if the umaine.edu people frequent these lists. If not, since you are associated with a university, they might be responsive if you contact them directly.

httpd using 100% cpu, imap socket stuck in CLOSE_WAIT
by Roy McMorran 04 Apr '08

04 Apr '08

Hello all, Often throughout the day I see instances where an httpd process will spike up to 100% cpu utilization and stay there for an extended period of time. eg: 19068 apache 1 0 0 71M 49M cpu/1 9:05 48.11% httpd (that's a 2-cpu machine) This is a Roundcube process. If I run a truss on that pid I can see that it is doing absolutely nothing. Also lsof tells me: COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME httpd 19068 apache 39u IPv4 0x30012fd2380 0t0 TCP mail.example.org:63204->mail.example.org:imap (CLOSE_WAIT) This connection will stay in the CLOSE_WAIT state (and the CPU pegged) indefinitely, or at least until... ...eventually it times out and I may see this in the Apache error log: [Thu Apr 03 11:46:44 2008] [error] [client 209.222.195.177] PHP Fatal error: Maximum execution time of 300 seconds exceeded in /group/www/mail.example.org/htdocs/program/lib/imap.inc on line 169, referer: https://mail.example.org/?_task=mail&_action=show&_uid=114766&_mbox=INBOX Any ideas what is causing this? It's bringing the server to it's knees fairly often, and contributing to a perception among my users that Roundcube is "slow". This is Roundcube 0.1 stable running under PHP 5.2.5 / Apache 2.2.8 on Solaris 10. Our IMAP server is UW and lives on the same box. I'd appreciate any troubleshooting advice.

Will 0.1.1 be php4 compatible?
by Doug Mandell 04 Apr '08

04 Apr '08

I've got access to a server that isn't going to be upgraded to php5 (at least in the short term), I know you guys were planning on switching to php5 post-0.1, I was curious if the impending 0.1.1 release is php4 compatible or if you've made the switch already. Thanks, Doug _______________________________________________ List info: http://lists.roundcube.net/dev/

Please CC the lists! Did you update the schema when you went from 0.1-RC2 to 0.1-stable? Till _______________________________________________ List info: http://lists.roundcube.net/dev/
