Problems with Mail Transport Server

Same problem with same message: Wrongor missing login data to access mail transport server smtp.mailbox.org. Pleasecheck associated account's settings/credentials

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?

Hi,

I've been trying to send an email since I opened my account but it keeps saying

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

Also, I'm unable to subscribe to calendars.

I just signed up as a paid customer and I'm having the same problem - can't send email via either web interface or via activesync or imap; please help.

Please try again and let me know if there are still problems.

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!

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

I have the same problem. I haven't been able to send a single mail with my trial account, using the web interface or SMTP server.

Another person here with the same problem! Please advise how I can get this problem sorted, thank you! Rob

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?

We blocked your account due to spamming/phishing/malicious activities.

Mine is locked too. Can you please unlock it??

Looks like I was locked too. Can you please unlock my account? Also, let me know what I may have done to get locked up? I really have no idea! Thanks- J

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!

I have the same Issue

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.

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.
