thinking of deploying zimbra for an office of about 50 people(it was their idea)

obviously i have researched a lot, but was curious on perspective from users here who seem to be maybe a little more savvy and take the time to write nice long posts

interested in end-users thoughts as well as admins who can tell me honestly what breaks easily.

i usually prefer to do my own debian/postfix/dovecot/samba/apache/mysql/<whatever specific portals>, but this is a smallish install in a big rush.

i am testing a zimbra install on a linode 768 and honestly with even just me on there the memory and disk io is kinda scary
