01.com Zimbra FAQ's :: 01.com Zimbra enterprise managed services requirements

Expertise: none required. We can provide end-to-end assistance, from presales to migration, through maintenance, and even including 24x7 help desk support for end-users, or tier 2 help desk support for your help desk. You choose just what you need.
Licensing: We will license your organization Zimbra's top-of-the-line Network Professional Edition, Standard Edition, or Consumer Edition, based on your needs. (Compare editions)
To get started: use our Enterprise contact form to engage a 01.com Sales Engineer.
Domain name: you must have at least 1 internet domain. You may have an unlimited number of additional domain names on your server(s).
Server(s): We recommend Red Hat 5 server, or OS X server (version 10.4, version 10.5 is in beta). We support CentOS and others, too. We have standardized on HP Blades in 7000-series chassis in our data centers, and we commonly work with Dell, Apple Xserves and IBM hardware, too. And if you have a SAN available, that's typically optimal. We will help you specifiy the solution best for you based on understanding your current and projected usage patterns, operational needs and budget.
Hosting: host at your office(s), your own data centers, or use ours.
Migration: We have automated tools to migrate from popular systems such as Exchange, Notes and Groupwise. Cyrus/Postfix/Sendmail/Apple are all straight-forward operations. We have developed a flexible, custom, multi-threaded IMAPsync (imap sync) framework for any imap-compliant mail server, and also custom migration tools for other mail servers such as Ipswitch iMail.
Mailbox administration: use the secure Zimbra admin to add/delete mailboxes and perform basic tasks yourself. You can decide to have and use full access to the server, or use 01.com to perform more complex tasks and systems administration.
Security: We recommend and typically install 256-bit SSL encryption for IMAP, POP, SMTP, HTTP & LDAP, using public SSL certificate(s). With some system hardending, your Zimbra server(s) can be placed public facing, and we can place them in a DMZ, or behind a firewall using split DNS. We have secure methods for remote administration that meet stringent security protocols.
Organizational size: Typically 250 team members or larger. We do assist many smaller organizations, especially in the financial services industry, with their own systems that have compliance/control requirements, or custom integration needs, that preclude considering a cloud hosting environment.
Authentication: use Zimbra's built-in OpenLDAP, or we can authenticate versus other LDAP varients, such as Active Directory and Open Directory. We can also use secure preauth for single-sign on to other systems, such as CAS.
Integration: If you choose to use an external system for authentication, we have material experience designing automated provisioning and de-provionsing (pruning) scripts and services to synchronize various directory systems with Zimbra's OpenLDAP. Other common integration requests are with various third party solutions for anti-spam and virus, most of which are straight-forward.
Location: Your team can be together or dispersed. U.S. and international.
