SMTP Authentication failures

Hi

 

Out of the blue at least two of my mailboxes (I haven't yet tried them all) have failed due to SMTP authentication failures and the connection being refused.

 

With one mailbox I changed the password then after about 30-odd minutes it started working. The other mailbox was working perfectly last night but has failed this morning. I've changed the mailbox password but it still won't authenticate EVEN FROM WEBMAIL where I'm successfully logged into the mailbox with an SMTP error 535.

 

What's going on?

Re: SMTP Authentication failures

Sorry to hear that.

Can you advise further what happens when you try to send an e-mail from webmail.plus.net?

Re: SMTP Authentication failures

Hi
Thanks for the reply.

From webmail.plus.net I could successfully sign into the mailbox but it failed to send an email with SMTP error 535.
I kept trying and after maybe 45 mins it sent successfully. From then on I could authenticate from my other devices and email client.

So, it's sorted out now but I still don't understand why it happened out of the blue.

Any thoughts?

Cheers

Re: SMTP Authentication failures

Hello @samo,

 

We are happy to hear that the issue is now resolved, unfortunately as the issue is still not on going it is hard to say what could have caused it.

 

 

Please keep an eye on it and get back to us if the issue reoccurs.
