In the interests of allowing the Mac Pro to be able to function adequately with a “normal” server, we’ve had to update the server – this was a final (and very effective) fix for the troublesome repeat-email download problem.
Basically, the primary email id forwards to a secondary id. Primary id is configured on all portable devices, as well as the Mac Pro’s OUTGOING settings. The INCOMING settings on the Mac Pro are set to the secondary email id – with “save on server” set to off.
Seems all Mac based email clients have trouble while saving email on the server – even if you’re using Gmail you are _forced_ to set it to “do not save on server” and then alter some of the Gmail account settings – it’s quite bothersome! Of course IT is expected to support the device so it’s natural that we need to fix any issues that happen. The source of the issue is not relevant.
Here’s a pic that explains what we did to fix it.
All else aside – this final solution worked brilliantly for our requirements. Very happy with what we’re able to do now – at the slight disadvantage of having to deal with 2 accounts – but with the major benefit of all email software on the Mac Pro functioning normally. Wooot!!!
