Mail rate limit

Hi Guys

I have recently been informed that a couple of customers have been getting a error message whilst attempting to send an email via the usermin interface. The errors says something along the lines of can't send email as you have exceeded your quota (We have the Mail Rate Limiting set on the server) But it appears we are not having the issue with exceeding quotas with customers using mail clients to send mail even on the same domain. So it seems localised just to usermin.

Can you please let me know if you are aware of this type of issue, if not then I will attempt to provide better information to assist.

Please note we are also using authentic theme.

Thanks Michael

Howdy -- we haven't heard any reports regarding Usermin being an issue, but not other clients.

Just to verify, do you have Mail Rate Limiting installed/enabled within Virtualmin?

Also, what is the output of this command:

postconf -n

And if you have any other details, that'd be great too. Thanks!

Hi

Yes I installed rate limiting via virtualmin

Output of postconf -n

Enter a shell command to execute in the text field below. The cd command may be used to change directory for subsequent commands.

I will try and get the exact error message for you soon.

Thanks Michael

I'd be interested to see the exact error message, as that would indicate if the mail rate limit is the cause, or just a lack of disk quota for the user.

Hi Jamie

Error is attached, First thing I looked at was the quotas and they were all ok.

Thanks Michael

What gets logged to /var/log/maillog or /var/log/mail.log when that error happens?

It should provide some more useful details from the mail server..
