Wiebe works at YTEC, where he is a senior developer of customer-specific tailor-made software (“klantspecifieke maatwerk software“) for clients in a few select markets: wholesale, printing and healthcare.
My HP4050 has a million different drivers to choose from. Some don't have the maximum DPI, some don't have other options, like selecting paper output. The one that works the best seems to be "HP LaserJet 4050 Series Postscript (recommended) (grayscale, 2-sided printing)". However, I have no idea anymore if that came from hplip, foomatic, gutenprint, or whatever.

These are some short stepts and pointers to setup a postfix fallback MX. It does not describe postfix basics, nor how to install Mailscanner (a necessisity, because spammers like sending spam to fallback MX's because they're usually not as well protected).

I always seem to forget this, and the mailq command is not clear, so here it is: when you type mailq on a postfix server, the first address listed is the sender, the second the recipient.

(Hmm, this suggests the python version might be better).

I installed a commercial (free) SSL certificate from Startcom SSL in Zimbra. I basically followed this, except the java keytool thing. I don't know why that is necessary... I did this on Zimbra 6.0.10_GA_2692.UBUNTU8_64 UBUNTU8_64 FOSS edition.
