We have a document which talks about mail clients and not so much about mail servers: https://www.kernel.org/doc/html/latest/process/email-clients.html but in general, use a linux system to create and send your patches and avoid Exchange for patches because it is notorious for mangling them. Most kernel people I know use emacs or mutt with an imap account through which they shuffle mail with fetchmail etc. HTH. -- Regards/Gruss, Boris. https://people.kernel.org/tglx/notes-about-netiquette
