I don't _have_ a gmail account and don't want one. All the guidance I find for dealing with gmail seem to assume an existing gmail account. My host sends mail directly to the recipient. The very few messages to gmail addresses bounce, all else goes through. I can understand the requirement of a gmail account for bulk mailers, but I'm not one. I've set up an SPF entry in my DNS. The most readable description of TLS with sendmail is https://www.linuxjournal.com/article/4823 but it's quite old, 2001, is specific to Linux and makes no mention of gmail's new requirements for authentication. It looks like all I need is SPF and TLS, if "Requirements for all senders" at https://support.google.com/a/answer/81126?hl=en#zippy=%2Crequirements-for-all-senders is correct and complete. There have been suggestions it is neither, but it's a start. > DMA would be able to deliver email to gmail (or elsewhere). I need to both send and receive personal email. Thanks for writing, bob prohaska
