Mail settings - pop3 / smtp - Windows10 vs Windows11 - Outlook (classic)

[#1]

"As they are my email provider, I will. And, as PN also reccomend 587, I will use it on my PN account (via Greenby) until I close it in December."

But, once again - for the eleventeenth time - Greenby recommend port 465 for SMTP.

This is not a debating matter - it is what is says on the Greenby site. Anyone with a Greenby email account can verify this for themselves.

Email Client Settings (From Greenby Portal)

Incoming Server Address imap.plus.net
Protocol IMAP
IMAP Port 993 (Encryption Enabled)

Outgoing Server Address relay.plus.net
SMTP Port 465 (Encryption Enabled)

If you prefer to use the POP protocol rather than IMAP then please use port 995 with Encryption turned on

I know what Greenby suggest, but I am still using 587, with no ill effects.

https://mailtrap.io/blog/starttls-ssl-tls/

"These days, many email clients, Gmail and Yahoo! included, use both port 465 (for Implicit SSL/TLS) and 587 (for Explicit SSL/TLS), while others limit themselves only to 587.

Things are set to change, as further attempts are made to enforce the use of TLS in both clients and servers. In 2018, the Internet Engineering Task Force (IETF) recommended that using Implicit TLS via port 465 is the way to go. Time will tell whether STARTTLS will become redundant one day or if both approaches will be used hand in hand for years to come."

Its certainly tricky as taking greenby as an example they state (not sure see how it can be suggest or recommend if only one set of parameters is given?) 465 presumably in an attempt to get people to update settings?

However, as the outgoing server is plusnet it still works with the older 587/Starttls.

I cant see Greenby stopping legacy access via 587 though (example is those outgoing servers that have already moved from plusnet to greenby) as that would add even more threads to this forum when those users who migrated and have left their client settings as plusnet recommended 587/starttls suddenly find it doesnt work anymore

What I think made the difference this time, was changing postmaster@ username.plus.com to username@ username.plus.com.

... and yes, they might even work now with encrypted settings

Almost certainly the case. I would definitely try using encrypted settings.

... I'd left things as they were - mail.plus.net, pop3, 110 - relay.plus.net, smtp, 25 - no encryption

but today had reason to revisit all this again, because of needing to change leave-on-server settings for some Mythic Beasts (-hosted) mail addresses.

... and I finally discovered how to see (find, look at) what *settings* Outlook had used to save the plus.com accounts.

... not what I had put in there, though I'd not known how to check that before.

I went via start – control panel – small icons – Mail (Microsoft Outlook) – to Email Accounts and selected (highlighted) one of the plus.com accounts.  Then clicked "change" (above).

And this is what it showed me:

Account type: POP3

Incoming mail server: mail.enmail.co

Outgoing mail server: mail.enmail.co

... then clicked "More Settings" (on r/h side).

Incoming server (POP3): 995

(ticked) This server requires an encrypted connection (SSL/TLS).

Outgoing server (SMTP): 465

Use the following type of encrypted connection:  SSL/TLS (selected)

... just extraordinary.

Clicked on OK and returned to the 'Change Account' page.  Where clicking 'Next' served to test account settings.  Test e-mail arrived fine

So *somehow* Outlook has changed the originally-input settings to a - very different - encrypted set that *works* for plus.com accounts that have been migrated to greenby.

Only proviso I would add, if anyone else tries these settings, is that the original unencrypted set only worked with

username @ username.plus.com

(no postmaster, admin or whatever before the @).

... so I'd figure the encrypted set probably does likewise.

*

One last thing that may also be worth mentioning here, is that if anything is changed on the "More Settings" page, even if you click OK it doesn't *save* it until you return to the Change Account page and click Next and finish the sequence.

Has been another long and learning-curve type of day, but I feel like Outlook at least is finally sorted now.  For here, anyway   Hope others manage to get their greenby/webmail/outlook issues sorted some time soon.

From what i gather aliases cant be used for login settings on greenby and any alias email addresses would need to use the login details of the mailbox they point to.

Whilst postmaster@username.plus.com is used for billing email its not an actual mailbox. By default mail sent to it ends up in username@username.plus.com i.e. it appears to be a built in alias.

I believe admin@ is also not present by default as a mailbox and probably points to username@username too.

Any other name@username.plus.com and associated password that is a mailbox should work with those authenticated port details

Edit: changed .net to .com

I don't know, so if I am wrong, ignore me, but does Outlook (any version) store settings in a profile which can be copied to a new machine? Only going off my Thunderbird program.

It’s something that used to be possible but for more recent (> 2019) versions of Outlook trying to export and import server settings isn’t reliable or worth spending time trying to do.
