Think of using IMAP for accessing GroupWise?

Question in the NGW List: What difference is there if you enable imap on gwia or directly on the poa?

Answer(s):

Functionally? – no difference.

Performance? – you get a little quicker response from POA. When hitting GWIA, it has to talk to the POA to get the requested data, then supply it to the IMAP client, so hitting POA directly removes that step.

If you have multiple PO’s, it’s may be confusing for your clients, as each PO has it’s own address (duh!) so you have to tell each user the correct PO addr or hostname. There is no redirect for IMAP like there is client/server protocol

Firewall? – You may not want to have traffic inside your firewall even though you could restrict it to the IMAP port(s)

Security – Even though there is no difference here, thought I’d mention it and reccomend that you use SSL or TSL only as for non-secure connections, the passwd is sent in the clear.

Reliability – Not really much difference, if something IMAP related would crash GWIA, it would probably crash POA as well, the share the same IMAP code. Can you afford downtime for your post office if it does?

One more big difference though that you and I probably care about more than the average admin – the POA IMAP has almost no logging of IMAP transmissions, and troubleshooting can be more difficult. The GWIA logging gives much more info.
