I like kmail. It is the default mail client for KDE desktops. I have used Thunderbird for a long time now, but kmail is equivalent. So is evolution, which I use as well. Ultimately they all do the same thing; they are mail clients. Each one has comparable features, although they all look slightly different. I tend to use Thunderbird, but have grown an affinity for kmail. In particular, when Using Gnome I use Thunderbird, and when using KDE I use kmail.
MythTV Frontend – So Many Choices »« Extended VirtualBox Management – VBoxTool
I have a virtual machine, a MythTV server, and an email server running on my computer at home. The compiz desktop environment will lag substantially when I get home from work. I conclude that this is because during the day the desktop interface is not being use therefore it is thrown to the swap. There are several things that can be done to alleviate this lag.
1) The easiest thing to do is turn the swap off completely. This is done with a simple command:
sudo swapoff -a
2) I can logout of the desktop session to the GDM window.
Then after logging in the desktop session will be new in memory and will be responsive accordingly. The problem with this is that I need Thunderbird for its mail filtering capabilities. I can do mail filtering server level with Sieve, but I cannot get it to work right. I don’t know why it wont work, but to get around the problem, and achieve the same functionality, I use Thunderbird which is a graphical application. TO use Thunderbird I need the Gnome desktop fully loaded. EOS (End of Story).
3) To help with the situation you can renice running processes to help you desktop environment get better priority with the processor. Overall I wish I could get Sieve working, then I could just logout of the desktop session when I am done using it. The server would just run in the background using a “nohup” command, but im stuck with needing Thunderbird’s mail filtering. So for now I’ve turned the swap off to maintain system responsiveness. This is working ok because of the 8 gigs the system has. I will try to get Sieve working again.

If you add the VBoxManage startvm command directly in your sessions manager you are limited to launching 1 virtual machine. Alternatively enter the commands in a single script, place the script in your home directly, and add the script to start on boot. A simple script would look like this. #!/bin/bash VBoxManage startvm server VBoxManage startvm server2 VBoxManage startvm server3 thunderbird ect…

I though by implementing some blackhole lists that spam would significantly reduce. Technically it has from several hundred to several dozen, but wow, spam is relentless. Spam still finds it way to my inbox, no matter how well trained Thunderbird is. I currently have no 100% solution, and its driving me crazy. I usually figure things out, but to eliminate 100% of spam is proving to be an unsurmountable task. I mark new spam messages every day, but they still find there way in. Simply wow.

Combing through many free domain blackhole lists the following are relatively extensive, and are readily maintained. combined.njabl.org list.dsbl.org dnsbl.sorbs.net spam.dnsbl.sorbs.net Using these blacklists in your sendmail configuration can reduce the spam received from the most common and prevailing sources. Combining these active spam prevention measures, with passive techniques spam can be greatly reduced. Passive spam prevention includes blackhole lists that are not controlled by you. You can also implement graphical active spam filtering using Mozilla Thunderbird via filters.

If you have dovecot setup to use IMAPS, then you can connect using Thunderbird on port 993. If you use the default dovecot.pem certificate you will notice that you have to accept a warning each time you access your email. This warning is because the ssl certificate that is automatically generated by dovecot does not use the hostname of the dovecot server. To fix this issue you have to create an ssl certificate that has a hostname that is the same as the server. For example, this domain is www.bgevolution.com; to avoid the warning the ssl certificate will have to have the same hostname.
To achieve this feat openssl is used. Openssl is automatically installed on Ubuntu, and Debian therefore its just a matter of plugging in the right options and viola no more warnings. There are many options, and different algorithms that can be used, but the following will work just fine. openssl req -new -x509 -nodes -out /etc/ssl/certs/dovecot.pem -keyout /etc/ssl/private/dovecot.pem -days 365 Given that you have already configured dovecot for ssl access the openssl command above will automatically place the generated certificate in the default directory defined in dovecot.conf. The main thing that Thunderbird looks for is the “common name” or “general name” that is defined in the certificate. Therefore when openssl prompts you for that information make sure its the same as the hostname that you have input into Thunderbird to connect to your server. Viola, no more errors
