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.

"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
