<p dir="auto">Dear Scott and Benny, thank you for the answers that confirm my worries. I do use Mailmate tags extensively, I currently use about a hundred of them, including 4-5 of the classical custom IMAP keywords. The only other mail client I use is Preside on my iPhone, which is very good but, as you explain for the other clients, cannot “read” the tags. I also checked Thunderbird recently, but it still does not work.<br>
Too bad for me.</p>

<p dir="auto">My understanding, as a non expert in mail clients’ subtleties, is that it is impossible to transfer tags (or smart mailboxes based on tags) from Mailmate to another client (except for a few IMAP keywords). Is it absolutely impossible, or is there a workaround?</p>

<p dir="auto">Scott already gave a thorough answer. I'll just add some random thoughts:</p>
<ul>
<li>Not all servers support IMAP keywords, in particular, Office365/Exchange. In those cases, MailMate will quietly (which is kind of bad) make them local-only.</li>
<li>Some server have a limit on the number of IMAP keywords which results in various silent errors (like tags getting cleared shortly after being set).</li>
<li>Thunderbird has, I think, 5 custom IMAP keywords. Tags can be created in MailMate which map to those keywords and then they should work nicely together.</li>
<li>Colored flags in Apple Mail also uses IMAP keywords. MailMate mirrors this behavior.</li>
</ul>
