You’re hardly gonna get an answer here, because I’m not aware of many users using Incredimail in here (maybe I’m wrong). Why don’t you try to ask on some Incredimail forums (if there are any out there). Probably, they know more about setting that client.
Also, open those properties or settings page in incredimail and go through all those options. It shouldn’t be too difficult. If you find something like SERVER TIMEOUTS, you’re back on track again…
Hope you’ll solve your problem soon !
Cheers !
