I don't have any available icloud addressees, I did think of sending a test email to postmaster@icloud.com...
I have just sent three test emails to @gmail.com addressees, so will see what happens, if anything.

You will no doubt be delighted to hear that all three messages to the Gmail recipients have been returned as "likely unsolicited email"! 🤣

The mail system

Will look into this further, but doubt I will be able to do much about it myself.

I mean that when you use webmail, you do not have the need (or even ability) to specify what email settings are used for server, port, encryption or authentication, as webmail does that for you depending on your account and mailbox. Inbound will be a IMAP server, outbound SMTP.  In my case they may be mail.force9.net and relay.force9.net ... but I have no idea where those addresses are routed to.  Note that I do not normally use webmail myself!

I think that the SPF, DKIM and DMARC used probably currently varies with the Provider you sign on with (Plusnet, Force9, etc), possibly by your domain name, and indeed the effects are intermittant as well. I do know that Greenby are struggling to get it implemented globally which is why many of us are suffering badly with email bounces from various places. They said to me that "We are treating this as a high priority and are working directly with BT" and  "we are aiming to have this solved within a week" but I was first told this above on 20/03/2026 22:19:06 ... which is now three weeks ago!

Have sent a message to Google. Have to wait and see...

Perhaps it will be rejected as Unsolicited mail? 🙄

[#4]

I see that @MisterW has posted a comment here https://community.plus.net/t5/Email/Please-Help-me-stop-unwanted-emails/m-p/2042934#M60031 that partly addresses my question about DKIM at the end of message #30 of this thread.

[#5]

@mavison 

I thought we were informed that relay.force9.net goes out through Greenby servers but relay.plus.net still goes through Plusnet's avasout group of servers .... but I don't know what to believe any more!

Re DKIM: March 20th - huh @EBenny can beat that, see https://community.plus.net/t5/Email/When-can-we-reach-iCloud/m-p/2039718#M59003

@abitpedantic 

Do you mean this? So emails sent via Greenby webmail go out via relay.plus.net, not mail.enmail.co?

webmail connects internally to the local SMTP server,. Since webmail is hosted on the Greenby servers I assume it's connecting to the Greenby SMTP.

[#7]

@abitpedantic 

You were originally asking a Webmail user what server settings they use. I was trying to point out that they have no control or knowledge of any server settings, as webmail does it for them.

Re relay.force9.net and relay.plus.net addresses: There was a post that suggested they were indeed currently targetting greenby & plusnet. Eventually they will all be grenby ... though I assume the current names can still be used.

[#8]

My understanding is that the outgoing server for all plus.net users is relay.plus.net.

This is regardless if you have been migrated or not.

The exception is if you leave before migration as this action removes your account/auth on relay.plus.net. Workaround is to use relay.force9.net not mail.enmail.co

mail.enmail.co might have been suggested by greenby support but doesnt appear to have dkim etc setup. Given webmail for migrated plusnet accounts is using relay.plus.net suggests that this is still the correct outgoing server to use.

If you leave before your mail account is migrated, you lose that account, so I doubt any SMTP server would work.

From the Greenby portal, they give the current settings for my migrated Plusnet email address as:

Incoming (receiving) server
imap.plus.net
Port 993 · Encrypted

Outgoing (sending) server
relay.plus.net
Port 465 · Encrypted

Note that the above servers have different IP addresses.

[#11]

Sorry i meant plusnet broadband accounts after migration that subsequently leave whilst relay.plus.net is still plusnet

Yes, greenby are giving these settings now but reading through other threads/posts on here has greenby support previously giving out mail.enmail.co and in some cases suggesting using port 25

Now Greenby are giving out those settings (although are their support agents doing the same?) re enforces that migrated plus.net accounts should not be using mail.email.co for either incoming or outgoing servers.

[#13]

@njay Port 25 is not the correct one - it can work, but is really for MX to MX transmission. The correct port is 587 - 465 if your mail program is an old one that can't handle the default 587.

[#14]

Yes, i know. Thats why i highlighted it as anyone using it should really not be using it

[#15]

So, @njay may I ask my usual question. Can you send successfully to gmail and icloud addresses from a .plus.com address and if so, why do you think it works for you?
