SMTP Error 535 using plusnet webmail

Hi

in the last few weeks I have been getting SMTP error 535 when using plusnet webmail. It was a little random and a few attempts, log in/out and it would eventually send. Now Im trying 10x or more and cant send email.

 

any idea on any settings that might have changed or what I can try ?

thanks

Mark

Hi @t72bogie

 

Thanks for getting in touch.

 

Could you confirm that this is happening directly from our webmail program (eg, the one that you access via https://webmail.plus.net/) rather than a mail client such as Outlook etc?

 

If you have a client installed does this issue replicate itself across both platforms?

 

Best wishes

 

Dave

Thanks for confirming that, @t72bogie

 

Could you drop your username across via a PM and we'll take a look at this for you?

 

Best wishes

Re: SMTP Error 535 using plusnet webmail

Error 535 is a SMTP authentication error.

If this is being seen when using webmail, it somewhat suggests that webmail is receiving credential rejections from the SMTP server for your account.  Given that this is seen to be intermittent, I doubt that this is a password or email configuration problem.

Re: SMTP Error 535 using plusnet webmail

Thanks for your post, @t72bogie.

 

We're sorry to hear that this issue has gotten worse for you.

 

I've just raised this issue to our NetOps team for further investigation and would now expect an update within the next 3 working days. IIMH, it's usually a lot quicker than this but I have to advise the maximum timescale.

 

As soon as i receive a response I'll update this post.

Re: SMTP Error 535 using plusnet webmail

I'm glad to hear that you're able to send emails again now.

If you've made no changes then I'm unsure what fixed the issue as it looks like our engineers have come back to us advising that there were a very large amount of attempts to send mail using an incorrect password.

It's odd as you're using webmail and presumably logged in fine with your password. I'd recommend keeping an eye on it and it happens again we recommend to try resetting your password from the Madasafish portal Here.

Let us know how it goes.

Re: SMTP Error 535 using plusnet webmail

Thanks for getting back to us Mark,

The forgot password tool on the Madasafish portal seems to have intermittent issues.

Happy to call you back to change your password this side if you're free? Feel free to PM me your contact number

Cheers for your time on the phone Mark, fingers crossed the new password does the trick. Let us know though if this issue crops up again and we'll raise this back to our networks engineers for further investigation. Smiley

@t72bogie 

Pleased to hear that this issue appears to be fixed.  This is a really interesting webmail problem, so I've been discussing this with the support team - was the 535 error "qualified" with supplemental information, for example like...

"535 Too many SMTP auth failures. Please try again later."
