Any recommended client on MAC?

Any recommended client on MAC?

Hi guys. Have been using zoho for a while for my small business. I'm all happy with it except that on my iMAC I couldn't find a mail client that would sit well with zoho mail. I've tried like 10 clients. All have issues with zoho in connection.

Simply put, if I use imappro.zoho.com, all the clients would pop up a error every now and then saying couldn't connect to the server. I switched to imap.zoho.com. Mostly it's good, only that sometimes especially when writing a email, it would pop up a error telling me outgoing connection is temporarily blocked, something like that. It would unblock itself later, but still it's very annoying. Not being that software illiterate myself and helped with a bit search, I understand why I'm getting that error. So I just want a solution. BTW, using the webpage zoho mail is not a good enough solution.

Having said that, on my android phone, I use GMAIL and zoho client on my IPhone. They all work without fail even once.

Thanks for your help.
