I use sendgrid.com which for my level of traffic is free, and has worked. In recent months gmail has started putting my emails in spam, even for people I regularly communicate with, and even if I reply to their emails. Gmail's spam filtering is clearly not very good. I might have to switch gmail destinations to route through sendgrid.net as well.</div><div><br></div><div><span style="white-space: break-spaces;">Regards,</span></div><div><span style="white-space: break-spaces;">Martin</span></div><div><br></div></div><div id="geary-quote" dir="auto"><br>On Fri, Jun 9 2023 at 07:43:19 +1000, Russell Stuart via linux-aus <linux-aus@lists.linux.org.au> wrote:<br><blockquote type="cite"><div class="plaintext" style="white-space: break-spaces;">I'm after an SMTP relay service, ie something that accepts email via SMTP on some port other than 25, and relays it for me.
The reason is my families email server is one I run myself from a server sitting a home on a NBN connection with a static IP, but I'm moving house and will lose access to a static IP for a year or so. The simplest thing seems to me to move my email server into a VPS, but it seems VPS's now near universally block outgoing connections to port 25 for new customers for understandable reasons.
The VPS providers say you should use an SMTP relay service instead, and one even suggests a free one to use. But the suggested free one hasn't respond to my new account request. There are others I can try, but following the other Russell's example I thought I'd ask here first.
