Exporting emails to Gmail

[LesleyMac05]

I'm trying to move my Blueyonder emails over to my Gmail account using the MailJerry app on my Windows 11 PC.

It is failing on the Blueyonder login although I'm using the same credentials from the app on my phone.

I asked MailJerry for help and they responded :

"I had a look at your use case: Your source server reports that the entered credentials are not valid:

"Host1 failure: Error login on [imap4.blueyonder.co.uk] with user [[removed]@blueyonder.co.uk] auth [LOGIN]: 2 NO [AUTHENTICATIONFAILED]

Did you try the following advanced settings?

IMAP Port 993

SSL Encryption: TLS (you could also try SSL)

If this doesn’t help, could you please reach out to your old provider and ask them to whitelist our IP 128.204.135.193? It’s quite rare, but some providers don’t allow IMAP access for IP addresses from countries outside."

I have tried the entering the port number but can't change the security setting away from "auto".
I've also tried IMAP.virginmedia.com. The login still fails.

The next thing I'd like to try is getting the IP address 128.204.135.193 added to the Virgin Media whitelist.

Any idea how to do this?

TIA

A friend suggested I try POP3 migration and I found out that a new App Password had to be generated for that too.
So, I created one and got POP3 Gmail Import working successfully for the Inbox only. I then manually deleted the originals from the VMAIL inbox.

Onto IMAP with MailJerry for my folders....
Another App Password had to be generated in VMail and then one in GMail too.
As there is a 250MB limit on the free option, I invested £11 on a monthly plan for the first month that will synchronise for the rest of the month. 
The migration kicked off great and told me it would take over an hour so I left it alone. When I returned, it appeared stuck but when I looked at the "Migrations" page it had completed OK. All look good with slight adjustments to duplicated labels (eg Finance/Financial)

Downside is - now my PC App and phone apps don't sync with VMail as credentials are wrong!
I'm not changing it again so I'm hoping the MailJerry sync covers it OK.

FREEDOM!!!!

Thanks for your help 🙂
