Check which ports are open to the outside world. Helps make sure that your firewall rules are working as intended.
One of a set of tools we are providing to everyone as a way of saying thank you for being a part of the community.
Beware however that Groupwise uses several techniques to reduce database size: If mail is sent between users in the same postoffice it is only stored once, with pointers to it in one users's sent mail, and another user's inbox. Especially when you are migrating to a different email solution you have to take that into account.
You can also use GWCheck to determine the size of the individual mailboxes:

As stated above, the total of all individual mailboxes will be bigger than the total PO size. The difference will at least be a factor 2, but can be as high as 10 times bigger. (e.g. lots of mails with big attachments sent to Everyone)
