Same message in webmail.

If I try Thunderbird, it says:

Sending of the message failed.

The message could not be sent using Outgoing server (SMTP) smtp.mailbox.org for an unknown reason. Please verify that your Outgoing server (SMTP) settings are correct and try again.

Maybe it's because I have a brand new account that was only activated a few hours ago?

Your account was locked by our anti-abuse system. I unlocked it.

Hi,

I'm facing the same problem. I can't send mails via the web-client. The Android client doesn't work either.

I subscribed/paid yesterday - that should not happen.

Error pop-up box reports:

"Wrong or missing login data to access mail transport server smtp.mailbox.org. Please check associated account's settings/credentials."

Hey. I have created an account and just set up my personal email. Having the same problem as I tried to reply to the first message I had sent to myself from another account. Can you please take a look to see what this is?

Thanks!

I guess I found out my problem. I was using a VPN service, and I just learned that most VPN providers block SMTP by default. You have to reach out to them to open up your specific mail server. This was not a mailbox.org problem. :)

Same problem! Account opened yesterday and I have only been able to send one email through Thunderbird, then I suddenly got the same error message. I spent one full day trying to figure out if it was the wrong settings in my client, but every attempt resulted with the same error. Then I tried with the webmail and got the same credential errors. Tor support is advertised, but your onion address is not even reachable. It's clearly your fault.

I think that for me it's time to give up, close my account and go elsewhere because if there are troubles like these after one only test email sent, then I really don't know what to expect during normal usage. An email account is supposed to allow a simple job like sending emails, but this one seems to be designed only to make people frustrated and waste their time in trying to fix something that they just can't since the fault comes from the service itself. Considering that email servers exist from decades and they are know to work reliable, it's simply unacceptable troubles like these. If your custom anti-abuse system considers an abuse the second test email sent in the whole life of the account, then you need to revise completely its design or, even better, replace it with other ones that exist from long time and are known to work.

I am so disappointed to be forced to change the good review in my blog because after all, when the service was working, it was pretty nice.

I hope that one day in the future you can fix these troubles and give your service a second chance.

Thanks

Hi,

We're recently worked very hard on this and had a working group meeting two days ago and will change the anti abuse stuff this week.

Right at the moment we're under heavy fire from spammer/phisher/criminals opening ten-thousands of accounts at mailbox.org. We have different ways how to detect this with our anti-abuse systems.

Right at the moment there are rare unwanted side effects for people coming from exactly the same network blocks like the spammers doing their registration right at the same time and in the same way like the ongoing spammer registrations are done. If that and some other conditions are also fulfilled, they're registration could be set to "possible abuse" so that the system locks outbound mail for those accounts to protect everybody against that.

This only affects fresh registrations under rare condition. This does not affect existing older/existing accounts, so this has nothing to do with "normal usage".

We developed some new ways on how to detect this massive abusive account registrations so that we're very optimistic to solve thies unwanted side effect problem in the near future.

Similar problem here. Connection to IMAP is stable, but SMTP hangs for several minutes before coming back with "msmtp: the server sent an empty reply". I was able to send a message to myself over web interface though. What would you advise?

I managed to get to the bottom of this on my own. All over the website it says SMTP server port is 465, and at least a month ago it used to work.

But last few days all I was getting on that port is:

murchik@moover ~ λ openssl s_client -debug -starttls smtp -crlf -connect smtp.mailbox.org:465
CONNECTED(00000003)

So it accepts my connection and freezes. By randomly poking around I found that port 587 accept connections now, and it works perfectly well.

I tried both msmtp and openssl clients to test this. I also tried doing so from several different locations, including one in Germany (a Hetzner server). Results were consistent.

Is this an expected behavior or is it a misconfiguration? If it's the former is it documented anywhere? If the latter, do you guys have any monitoring to detect this kind of things? Or does anybody pay any attention to user complaints?

I don't think this forum is attended by MB staff much, I think if you "create a ticket", you will get a response within a week or less, you have to find the German ticket option

btw, do you use a VPN ? if so which one ?

Hi,

I am facing the same problem. I didn't even manage to send one email, but I received this error. I was trying to send some test emails to myself and my mail aliases from my test server (located in a different location from me):

"Wrong or missing login data to access mail transport server smtp.mailbox.org. Please check associated account's settings/credentials."

This is not spam, as I am sending emails to my own mail aliases for the purpose of doing email signups from my website. Please unlock my account for me.

Thanks!

Just opened an account and can't send any emails from the web client. This does not speak highly of your service. I'm not using a VPN and tried disabling all antivirus. If the trial doesn't work I'm certainly not going to pay for it. Will try Posteo instead.

Thanks. I just noticed that. I used Microsoft Outlook 2007 to move all of my messages, folder to folder, from my ox.io account to this new mailbox.org account. Thanks for the 18 month voucher you all sent me to the ox.io account. I look forward to trying out the mailbox.org service during this time.

Since yesterday i cannot send any e-mails with attachments, neither from local Thunderbird, nor from online Mailbox.org web site. Very small e-mails seem to work. but as soon as there is even a small attachment (400K) included it fails. Thunderbird tries differing from 35% up to 100% (!) but finally fails with timeout from smtp server. Sending via Mailbox.org website starts ann becoming slower over time, reaches 100% but than hangs and finally retries, but never completes.

Same here, but it seems to be network-specific; it does not work from my home network (USA) but does when connected via a VPN.

We're investigating this case and it seems that this is a problem from the customer's local carrier. Most customers having this issue are customer of Unitymedia and/or some else ISP that uses LibertyGlobal as data carrier.

Please open a ticket at your local ISP.

Additionally (!) you can also open a ticket a https://help.mailbox.org -- please provide your ISP and your local dialin-ip. Thanks.

Hi Peter, I submitted ticket MAILBOX-8120 with a lot of data on this - traceroute and tracepath outputs, packet captures, etc. There is a chance the problem is 50% packet loss along the last few hops of a certain path near to your network.

Thanks, that's very useful and exactly what we're looking for. Yes, we think that some 3rd party carrier has routing issues here. NTT isn't our main carrier. This just some transit traffic here like it happens all over the word and has nothing specially to do with mailbox.org. Our team will try to get in contact with them. I think, they'll know that they have issues there...

Hi, I am also having a similar issue. I just created an account a couple days ago and I wanted to test out how the service works with a test email and it's not working. Its giving me the same error code that other have mentioned in the past.

I would love to get some help. Did my account accidentally get locked?
