Error - no such user here

[setter]

Hi
Totally new here so massive apologies if I’m posting in the wrong place.
I’ve searched both the forum and faq for a solution but sadly had no joy.

I tried to send out a newsletter a little while ago from one of the websites and everything went swimmingly. But disaster struck when I clicked send.
Half a dozen or so newsletter sent then suddenly an error displayed saying: 'no user here' or 'no known user here' and everything stopped.
Basically I cant seem to send out any newsletters anymore.

The site in question is using zencart 1.2.6 on a windows server.

Has anybody else experienced this or could some one point me in the right direction please.

I'm probably wrong but my suspicions point towards the admin password that I changed a while back.
Could someone confirm if that could be the cause? And if so, could you please point me in the right direction to what other changes need to be made.
We can access every other part of the site without a problem at all.

Guessing wildly, but it sounds like it could be a database problem - incorrect customer/subscriber record, or a problem with the login to the mail server.
I'm not sure that I see a connection between admin passwords and sending newsletters

Can you give a more detailed example of the error message ?
A screenshot would be helpful too.

Does it happen only with certain email addresses ?
Some email servers will instantly reject an email if the email address belongs to a domain on the same server that's sending the email and it can do a validation before accepting the message. If it knows the domain doesn't contain such an address, it'll instantly reject it. Perhaps that's what's happening ? Can't tell without more info.

Many thanks for the quick replies. Really appreciate it.

I'll get another newsletter prepared and send it out as normal and make a carefull note of everything that happens and come back.

Many thanks to you both once again.

I've sent another newsletter and it sent 41 then stopped. Here's the error:

Ran into problems sending Mail. Response:550 No such user here.

I did notice that if you hover over the green ticks the email address displays so I went through the customers file and discovered that the last 6 emails sent were customer that had subscribed to newsletters their id's being 107, 109, 110, 112, 113 then it jumps up to 862.

Funny thing is customer 862, I remember something happened with this customer and I deleted his account at his request so he could sign up again.
Could be just a coincidence but I'm wondering if he was originally 114 which is actually missing.

I saved the newsletter page as a html page and ran it in dreamweaver and the code implies that the error stops when it hits a email address that belongs to customer id 115.

Do you thing I should maybe delete customer id 862?

Bit stumped myself.

Do you have the newsletter subscribers mod installed?
It could be that the customer has been deleted but there is still an entry in the subscribers table in the database.

Thanks so much for the quick reply.

I haven't got the newsletter subscriber mod installed.
But I did take a peek at the database and looked in customers and saw that customers_id was a bit jumbled.
It started off 3, 9, 4... then caught up a bit but this is the cool thing, it went on numerically after around 15 right up to 111, 112, 113, 862, 115, 116 and so on.

That 862 has jumped in where 114 should be. But in the admin there isn't a customer 114. I'm starting to convince myself that 114 was this customers original id.

So what I did was clicked customer_id in the database to sort the numbers in decending order and that shows them as all in the right places numerically.

Do you think that might save the day?

Thanks so much once again

I think that if you are using Zen Cart 1.2.6 it should more accurately be the Subscribe! mod I was talking about. I seem to remember that this had a strange piece of code called subscriber_transfer_data.php or something similar, that moved customers into the subscriber table.
Unfortunately I don't remember whether it had to be run once, or every week/month etc., or even it's exact purpose.
I also remember that there was no easy way to 'unsubscribe' someone.

It does sound like you possibly have an entry in the subscriber table that no longer has a matching entry in the customer table, although the error - specifically the 550, suggests that it is a response from a remote mail server saying 'No such user here', which would imply that you have an out of date email address in the database.
If you are confident that it is customer number 862, change the setting to no newsletters for that customer, and see if that then stops the error.

Ok. I'll do that then. I really appreciate your help.
I'll leave it till the end of the week before I send out another newsletter and hopefully that will work just fine.

I'll let you know what happens.

Many thanks once again.

The change in numbers is likely a result of a sort of email addresses that happens before sending. I'm not surprised at it, and I don't think the numerical sequence is your problem.

As Chuckl suggests, it's likely best to disable that customer's newsletter subscription and see what happens.

You could try sending a regular email to that address and see what happens too.

Is that customer's email address something that exists on the same server as your website ?
