If you have a mail server at home and your Internet service provider (ISP) has no right PTR record for your assigned IP, you will get trouble the most mail servers will reject you.
Some best examples for mail rejection: gmx.de, mail.ru

local_sender_blacklist
This is a onboard exim possibility to blacklist special addresses, its only a optional file which contains a list of envelope senders whose messages will be denied;
1 | 550-sender envelope address noreply@rustock.net is locally blacklisted here |
Example of content:
1 2 3 | cat /etc/exim4/local_sender_blacklist noreply@rustock.net parker.ball@freeemailservice.info |
Restart or reload of exim is not required.
Another tricky error after Debian squeeze upgrade:
ERROR: Wrong ‘suhosin.session.encrypt’ option value. Read REQUIREMENTS section in INSTALL file or use Roundcube Installer, please!
The fix is very trivial:
1 2 3 4 | vim /etc/php5/apache2/php.ini # Add this lines to the bottom of the config: [suhosin] suhosin.session.encrypt = Off |
Solution for php5-fpm:
1 | php_admin_value[suhosin.session.encrypt] = Off |
To upgrade the database style to roundcube version 0.9.0 I used a little workaround to prevent suhosin error reporting:
1 | php -d suhosin.session.encrypt=off -d date.timezone=Europe/Berlin bin/updatedb.sh --package=roundcube --version=0.8.2 --dir=`pwd`/SQL |
I upgraded my Mail-server to Debian 6 – squeeze, it was everything great till I started my Thunderbird and get this Message: Filesystem notification initialization error — contact your mail administrator (check for configuration errors with the FAM/Gamin library)
This error can be seen in your mail client and is often caused by Courier. If you are the administrator of the mail server, simply install libgamin instead of libfam as follows:
1 | aptitude install gamin |
Now restart all courier services:
1 | find /etc/init.d/ | grep courier | while read line; do $line restart; done |
There are many configuration options with inpact on performance in Roundcube and behind it (Database and Webserver). As Roundcube installation administrator you can set them to some defaults and prevent users to change them by using the ‘dont_override‘ option.
I tested some options and created my tiny boost list.
Here’s the list of options with impact on performance
Messages listing is a main task of a mail client. Sorting is expensive. First of all you should use an IMAP server with SORT capability. If message list displaying is still too slow you should set ‘message_sort_col’ to an empty string.
