Keep Snow Leopard waiting

This week I've updated two MacBooks with Snow Leopard. Problems so far:

• Cannot send email anymore using our corporate server. Our server accepts only encrypted connections with user authentication. When I try to send messages, mail client just keeps on asking the password even though server answers that authentication is valid. I'm not the only one, check here.
• Our second machine had fonts messed up after the upgrade. Old documents were suddenly unreadable because the font was kinda packed, many characters were drawn to the same position. I was able to fix this problem by going to Font Book, selecting all fonts and validating all of them. Then I deleted and reinstalled the fonts that failed the validation - this fixed the problem. Again, I'm not the only one having this problem, check here.
• I wasn't able to watch some videos with Safari's vlc-plugin before I put Safari to 32-bit mode. To do this, open the properties for /Applications/Safari and select "Open in 32-bit mode". This is not probably Apple's fault, but annoying problem after the upgrade, anyway.
