Is relay.plus.net ok?

[#1]

I also know that an email address hosted by escrivo.com isn't receiving my emails sent via relay.plus.net

[#2]

It's an odd one. I've just sent a couple of authenticated emails to my GMail and Yahoo accounts and both turned up immediately.

escrivo.com looks to be hosted by Microsoft, possibly a 365 account. In all three cases, if there were widespread issues sending to any of these providers, I'd expect there to be much more noise about it

Thanks again for looking at it - it is very strange, but easily sorted for me just by switching to smtp.mail.yahoo.com, 

I think that so many people just use webmail these days that it's less likely to be encountered, coupled with the fact that I didn't know that the messages weren't being delivered until I BCC'd to my Yahoo address on a couple of messages and the messages never turned up.

At least if others do encounter it this thread is here, and if you need me to help with any troubleshooting I'm happy to.

Thanks!
