In this post, I will list some of the best Linux email clients for desktop. Some of these clients. 5 of the Best Email Clients for Mac By Mahesh Makvana – Posted on Mar 27, 2014 Mar 27, 2014 in Mac Although all the email services available let you access your emails via a web based interface, it is a good idea to have an app that can manage all this for you. As for my understanding, it shouldn't give a pop up saying 'connect to Office 365' since you are not adding the Office 365 account into Outlook 2016 for Mac but an IMAP account. If your client does give such a pop up, there should be a pop up whose up right corner saying 'not Office 365'. Paying for.mac (or some other IMAP) would give the same results as using AOL's free IMAP. The way around it, if I understand correctly, is to just take gmail out of the equation and use the IMAP email as my primary (only) email.
I'm used to Thunderbird, but I'm not attached to either one. Any reason to pick one over the other?
Changed topic to:
So, I set up Mail and it seems pretty nice, but there's one major problem..
It doesn't really sync with IMAP. I've googled, and this is a reasonably common problem (I don't think it's universal, otherwise there'd be major outcry, but I'm not alone here).
What happens is if the iPhone gets the mail 'first', no matter how many times I 'synchronize' or take offline/back online, or 'get mail', the messages don't show up until I restart the mail program (on the mac)
The same thing happens if I delete a message on my iPhone. It just stays there on my Mac. When I restart the mail app on the mac..poof, it disappears.
Is this an issue with my email server? A configuration thing? Like I said, I'm not alone in this, and it never happened in Thunderbird. It's kind of a big issue. Any ideas?
Outlook is one of the most widely used email clients in the business world. But with more smaller-sized companies starting to migrate to other, cheaper, solutions a lot of users are finding email clients that handle the tasks, without the headaches (and cost) that often accompany Outlook.
Email clients offer a variety of features; some features map perfectly to Outlook, some may not. Some email clients offer calendars, some stick with just the basics. In the end, what's important is that you find a client not only offers you what you need, but does so reliably and within your budget. I've found five solid email clients to help you migrate away from Outlook. Give these a look and see which one(s) might work.
On this page I see; Configure IPv4: Using DHCP with manual address IPv4Address: 10.0.1.5 Subnet Mask: 255.255.255.0 Router: 10.0.1.1 Configure IPv6: Automatically Router: IPv6 Address: Prefix Length: No where do I see a reference to a 'DHCP Client ID area'. 
I am on a MacBook Pro running 10.6.6. In system preferences, I open Network, click on 'Airport' then select the 'Advanced.' Button then the TCP/IP tab across the top. Am I missing it?

1 Opera Mail
Opera Mail is one of those clients that surprise a lot of people. Most have heard of the Opera browser, few know about the mail client. That is a shame as Opera Mail is quite solid, supports POP, IMAP (no Exchange support), newsgroups, RSS, and Atom feeds. Opera Mail has a nice list of features: Threaded views, spam protection, allows you to browse websites within tabs, and has a very simple (and lightning fast) user interface. Opera Mail is free and available for Windows, Mac, and Linux.
2. Dreammail
Dreammail is another lesser-known client that plays well with POP3 (no support for IMAP or Exchange) and allows you to set up and use multiple accounts and multiple-users. Dreammail does offer some handy features like templates and signature management, anti-spam, message filtering, address book, search, a built-in webmail tool, RSS support, and ESMTP/Google/Yahoo support. Dreammail is free and available for Windows XP/Vista/7 (no support for Windows 8 yet).
3. i.Scribe
i.Scribe doesn't have the most modern-looking interface. What it does have (more than most other email clients) is speed. If you're looking for the one email client that will work faster, and more efficiently, than nearly all others (except maybe Claws Mail), i.Scribe is the one you want. This mail client features: Support for most major protocols as well as international standards, can be used from portable drive, has a built-in baysian spam filter, enjoys frequent updates, and runs on both Windows and Linux. The i.Scribe email client is free.
4. Postbox
Imap Client For Yahoo Mail
Postbox is one of the best email clients for Gmail integration you will find. This application (available for both Window and Mac) is the only one on the list that isn't free (cost is only $9.95 per license), but does offer enough features to make the cost valid. Postbox includes: Social networking integration, native Gmail label support (even has a dedicated view for 'Important' labels and support for Gmail keyboard shortcuts), fast access to your favorite accounts, integration with services like Dropbox, and much more.

5. Evolution
Evolution is the Linux equivalent of Outlook. Evolution is also the only email client on the list with Exchange support. This client offers email, calendar, tasks, contacts, memos, LDAP compatibility, multiple account support, plugins, intelligent junk mail, powerful folder search, built-in encryption support, collaboration server support, and much more. Evolution is only available for Linux and is free (and open source). Evolution includes the Eplugin system. By default you can enjoy a number of plugins such as: Attachment reminder, Backup and Restore, Default Sources, Calendar publishing, Mailing list actions, and more.
Bottom line
Email is the single most important means of communication in the office. If your email client doesn't work well with your requirements, that communication is going to suffer. Though not every one of these clients offers a feature-for-feature replacement for Outlook, they will work splendidly with Gmail and POP (and IMAP, in some cases). Give these clients a try and see if they don't serve your email needs well.
