For clarity, can you logon to the account using webmail?
Can you send using webmail?
What platform are you on?
Are you on network or off network?
From what you have reported...
- You cannot send (that implied that you were logged on the the mailbox)
- The IMAP diagnostic with encryption fails due to server name mis match
- The IMAP diagnostic without encryption fails for not clear reason
I fear we might have become confused along the way here; you initially reported an issue with SENDING and I asked you to run the diagnostic tests which verify connections to all three servers IMAP and POP3 (inbound) and SMTP (outbound). You reported the IMAP results where I became focussed on the certificate error which echoes an issue reported elsewhere.
The IMAP text without encryption is thou also failing - which is confusing!
Can you please try using webmail, if you cannot log on there, then consider ...
Reset email password
If you are not able to login to the email address using webmail, then it is likely that your email address has been identified as being compromised and has had its password changed. Where email address passwords have been changed to protect the integrity of the service, the Plusnet account password is left unchanged.
Which ISP are you with, Plusnet or one of the other / legacy vISPs?
Plusnet / Force9 / FreeOnline users can only change the password on the DEFAULT email address by changing the password on the user ACCOUNT through the user portal. You can change the password on a secondary mailbox using the Manage My Mail options in the user portal.
Brightview users (Madasafish / FreeNetName / GlobalNet / IC24 / ICScotland / Dialstart / Totalise) logging into webmail should use their full email address. Use the MAAF user portal to update the password on the default email address (change the account password) and use this MAAF guide to change the password on a secondary mailbox address. If you cannot recall the account password, you will need to contact support ... because the account password change process sends an email to the mailbox you cannot now access.
DO NOT USE THE SAME PASSWORD AGAIN for that would allow the continued exploitation of the account. The new password should be cryptic and not one used before.
Note that changing the account password will change the password used for logging on to the relevant user portal. If your email service is NOT a retained legacy service (one associated with a retired internet service account), then the password required by the router to connect to the internet will be changed too. If the router is a Hub Zero or a Hub One supplied by Plusnet it should update automatically. If not, you will need to log into the router, drop the connection, change the password yourself and reconnect.
On the assumption that the email address password has been compromised, I strongly recommend that wherever you have used that email address / password combination as access credentials to services such as Amazon, Netflix, eBay etc., that you also change the passwords on those service as well.
Superusers are not staff, but they do have a direct line of communication into the business in order to raise issues, concerns and feedback from the community.
