Incident with atmail authentication (is email down?)

atmail

#1

Does anyone know when the email will be fixed? It is imperative that I get into my email ASAP as I have pending business that needs to be addressed today!!!


#2

Our Technical Operations team have pushed out a fix for the mail authentication issues we were noticing. https://www.dreamhoststatus.com/


#3

The issue on the 15th. was resolved when we enquired as to the cause the reply was “The issues can vary leading to the connection issues. This issue was related to a high load on the mail cluster you are located on. Once the load was lowered by the Server Stability Team the service functions returned to normal. If you still have issues please follow up with us”

OK, everything breaks sometime, but this is happening far too often, it is not working again now. Our email clients do not connect, almost as though our ISP is blocked except we can access email via Webmail, although I have to say that is the slowest mail server I have used during the fifteen years or so I have been using email.


#4

Unfortunately there is another incident open today that affects email systems. Please see https://www.dreamhoststatus.com/ for an update.


#5

Thank you for your reply. Email is OK today 18/8/17, I had looked at https://www.dreamhoststatus.com/ yesterday while our email was not authenticating and it claimed that e-mail was Operational. ‘When I use a word,’ Humpty Dumpty said, in a rather scornful tone,’ it means just what I choose it to mean, neither more nor less.’ ‘The question is,’ said Alice, ‘whether you can make words mean so many different things’.


#6

Same problem today. OK until 12noon UK time. After that no email via landline connection but able to via smart phone. Is there a fault on sub5.mail.dreamhost.com ? Once again status shows “operational”


#7

If the issue is only appearing on one device or network, I highly doubt the issue is on sub5.mail.dreamhost.com. When you see this behavior, it’s probably a networking issue somewhere between your desktop/land line and the remote server. Try to take a traceroute (instructions on https://help.dreamhost.com/hc/en-us/articles/215840708-Traceroute) and either open a ticket providing that information (better) or paste it here.


#8

I wonder whether the dreamhost server is restricting the traffic. Sometimes it seems to take a long time to authorise the email client to start downloading emails. I have done a traceroute several times, even setup a script to save to text file.

Today’s email is working OK

If the numbers are relevant node 19 looks slow

thanks for sharing the traces. The traces look complete, in both cases you seem to be able to reach the server correctly. 100 milliseconds shouldn’t really be an issue… What are you using on the desktop to read your email? What is the exact error message you saw (and where did you see it) on Monday p.m. when you noticed your email was not working?


#10

We have now had a resolution from Dreamhost support relatio=ng to Monday’s problem as follows:-
“I’ve looked into your situation and found out that your IP address 185.127.158.27 is currently blocked from the mail servers at our end…I have unblocked and temporary whitelisted your IP address so hopefully this should resolve the issue…To protect our mail servers from brute force attacks, our system will automatically block the IP address if it detects too many failed log in attempts made to the server within a short period of time. To prevent this in the future, please make sure that there aren’t any email devices or users at your end that may be trying to log in with the wrong credentials”.

As none of the users our end have changed and had been the same for years before we moved to Dreamhost in March, it is difficult to see what has caused “failed login attempts”, unless they are caused by dropped connections related to the quality of the landline which due to our rural location is not good.
