When and How to cache?
by Sven Hartge 29 Aug '14

29 Aug '14

Hi! I am currently deploying Roundcube as the main webmailer for my university. So far my beta-tests with a select group of users have been very positive. But before I push Roundcube on all my users who use webmail I wondered about the caching feature. When do I use the index cache? And how do I cache? Inside my MySQL database or via a memcached instance? My webmail service does not run on the same server as the IMAP service but on a different VM and in a different network but RTT between both is below 2ms. The documentation mentions that caching may even reduce performance in some situations but does not specify which situations. So far I have not be able to experience any slowdowns or speedups while using the index cache so I don't know if I gain anything by using or not-using it. Can anyone share any experience with the cache feature to help me decide. Grüße, Sven. -- Sigmentation fault. Core dumped.

Good day. Sorry for my English. I'm with Roundcube version 1.0.2. I would remove the "Response" item listing of the settings. Leaving only "Preferences", "Folders" and "Identities". Since alread, thank you.

ssl breaks roundcube ?
by ml＠ruggedinbox.com 22 Aug '14

Hi all! We recently improved our https configuration on lighttpd: https://www.ssllabs.com/ssltest/analyze.html?d=ruggedinbox.com but something seems to have broken roundcube .. can't properly attach files, can't send emails, sometimes can't logout. We are pointing the finger at ssl because when using roundcube as a Tor hidden service (thus bypassing ssl), everything works ok and smooth. Try yourself: username: demo password: demo11 under ssl: https://ruggedinbox.com/rc as a Tor hidden service: http://s4bysmmsnraf7eut.onion/rc What do you think ? Thanks for supporting!

Error on Moving/Copying messages from INBOX to nested folders within INBOX; works from INBOX to other Top_Level folders
by Admin DC 22 Aug '14

Hello, I first tried posting this with my gmail and didn't see it showing up on the archive. So I wanted to make sure this went through so I used a non-free email domain. If I created a duplicate thread I apologize. Now on to the issue at hand. We just oddly started experiencing this issue. We've spent quite a bit of time troubleshooting with logging increased on both our IMAP servers (Debian Wheezy 7.6 64bit with dovecot vers 2.1.7-7+deb7u1 ) I am absolutely able to reproduce this on numerous accts, even with logging up to 8 we do not see any "ERROR" or any reason why the copy and expunge would fail. Our production copy of webmail was older (0.9-rc), so I suspected possibly it was a bug or something wrong with that version, so we created a "ourwebmail-new.foo.com" domain and do an inplace upgrade on our database (to preserve our address book and other client info), with no issues on upgrade to v 1.0.2 Currently we have been diffing a successful copy/move and an unsuccessful copy/move and just cant figure out what's going on To sum up: INBOX to SOME_RANDOM_FOLDER has copy/move WORKING INBOX to SUB_FOLDER_OF_INBOX simply says "An Error Occurred: Could not move the message(s). Here's our adjustments on the config.inc.php for the new 1.0.2 version: # cat config.inc.php|egrep '^\$config' $config['db_dsnw'] = 'mysql://xxx:xxx@localhost/xxx'; $config['default_host'] = 'localhost'; $config['default_port'] = 1143; $config['smtp_server'] = 'smtp.xxx.com'; $config['support_url'] = 'http://www.xxx.com/xxx/'; $config['des_key'] = 'xxxxxxxxxxxxxxxx'; $config['product_name'] = 'webmail'; $config['plugins'] = array(); $config['language'] = 'en'; $config['spellcheck_engine'] = 'pspell'; $config['draft_autosave'] = 180; $config['enable_installer'] = false; $config['debug_level'] = 8; $config['log_driver'] = 'file'; $config['log_date_format'] = 'd-M-Y H:i:s O'; $config['syslog_id'] = 'roundcube'; $config['syslog_facility'] = LOG_USER; $config['per_user_logging'] = false; $config['smtp_log'] = true; $config['log_logins'] = false; $config['log_session'] = false; $config['sql_debug'] = false; $config['imap_debug'] = true; $config['imap_ns_personal'] = ''; Note: we tested with an imap email client (thunderbird) and could successfully copy/move within IMAP Please let me know if there's any other information I can share.

APC cause trouble with roundcube search
by Simon Vargas 22 Aug '14

22 Aug '14

Hello I have Roundcube 0.9.5 installed on Debian 7.6. Due to it was slow I read a tuning guide which recommended installing Alternative PHP Cache for apache. ii apache2 2.2.22-13+deb7u3 amd64 Apache HTTP Server metapackage rc php-apc 3.1.13-1 amd64 APC (Alternative PHP Cache) module for PHP 5 ii php5 5.4.4-14+deb7u12 all server-side, HTML-embedded scripting language (metapackage) I installed and enabled it with pretty much default config and I think it did improve on the performance of the server but users started experiencing problem with the search function of the mails. I'm not 100% sure it was caused by APC. Errors: - Roundcube search sometimes when find messages is not able to open them - Messages which were moved from the Inbox to other folders manually are not appear there - When opening a specific letter (result of a search) it loads in another one in its body After these errors I decided removing APC and manually deleting roundcube's index files. Did anybody experience similar errors?

Hi. I seem to have found the problem (it was in error in /var/log/apache2/error_log - I was looking in /var/log/apache2/ssl_error_log) [Thu Aug 21 20:17:42 2014] [notice] Apache/2.2.27 (Unix) DAV/2 mod_ssl/2.2.27 OpenSSL/1.0.1i SVN/1.8.9 PHP/5.5.15-pl0-gentoo configured -- resuming normal operations *** Error in `/usr/sbin/apache2': free(): invalid pointer: 0x0000000001197788 *** ======= Backtrace: ========= /lib64/libc.so.6(+0x78ff3)[0x7f0552158ff3] /lib64/libc.so.6(+0x7ebb6)[0x7f055215ebb6] /lib64/libc.so.6(+0x7fd92)[0x7f055215fd92] /usr/lib64/libmagic.so.1(+0x53d3)[0x7f054b0c53d3] /usr/lib64/apache2/modules/libphp5.so(finfo_resource_destructor+0x15)[0x7f054a428db5] /usr/lib64/apache2/modules/libphp5.so(list_entry_destructor+0x4e)[0x7f054a6b308e] /usr/lib64/apache2/modules/libphp5.so(zend_hash_del_key_or_index+0x28d)[0x7f054a6b0e5d] /usr/lib64/apache2/modules/libphp5.so(_zend_list_delete+0x61)[0x7f054a6b31a1] /usr/lib64/apache2/modules/libphp5.so(zif_finfo_close+0x59)[0x7f054a428d69] I've filed a bug with Gentoo.

Roundcube only attaches certain files
by Robert S 21 Aug '14

Thank you. I've added the following line to attachments.inc, below your highlighted line: error_log( 'Error: '.$_FILES['_attachments']['error'][$i] ); My error log gives [Thu Aug 21 20:09:01 2014] [error] [client 192.168.0.10] Error: 0, referer: https://mydomain.com.au/mailnew/?_task=mail&_id=34525533553f5c3d98798e&_act… - ie. the error code is 0 whether a file is successfully attached or not. I assume therefore that this is an apache or a php problem. Are you able to give any pointers?

Roundcube only attaches certain files
by Robert S 18 Aug '14

This is a very odd problem. I am able to attach/upload certain files, but not others. I'm not 100% sure about the exact types, but Word documents and .PDF files seem to be OK and I've been unable to upload JPG and RTF files. When I try to upload a file in Firefox, the spinner beside the name of the file in the upload file list spins forever. When I try to upload a file in IE it gives up and gives a "file upload failed" message. Nothing appears in the logs. Could this be something to do with line length in files (eg. RTF), or perhaps binary vs text files??? Its nothing to do with the size of the files - the .RTF file is only 5kb and I can upload a 46KB Word .DOC file. Some info: roundcube 0.9.5 apache 2.2.27-r4 php 5.5.15 main.inc.php: $rcmail_config['debug_level'] = 8; php.ini (additions to default): display_errors = Off log_errors = On error_reporting = E_ALL allow_url_fopen=1 allow_url_include=1 upload_max_filesize = 20M post_max_size = 20M max_execution_time = 60
