Hi all,
My hosting server does not allow the use of port 25 so I setup AnonAddy to with the use of the POSTFIX_RELAYHOST variables and use another server to send the email.

My setup works perfectly but once in the 2 months I get the below message.

I use AA only for myself so a max of 50 emails per month with 1 user.

Can anyone tell me how can I debug this?

The *USER_ACCOUNT* account has just finished sending 1000 emails.
There could be a spammer, the account could be compromised, or just sending more emails than usual.

After some processing of the /etc/virtual/usage/USER_ACCOUNT.bytes file, it was found that the highest sender was double-bounce@mail.anonaddy-domain.com, at 757 emails.

The top authenticated user was USER_ACCOUNT, at 1276 emails.
This accounts for 127% of the emails.  The higher the value, the more likely this is the source of the emails.
An authenticated username is the user and password value used at smtp time to authenticate with exim for delivery.

The top sending host was *IP*, at 1276 emails (127%).

This warning was generated because the 1000 email threshold was hit.

I'm sorry but I don't think I can help in this situation. I would recommend checking the mail logs on your other mail server on the dates when you get that message.

Unfortunately not. I still have the issue. It is a very annoying one.

Now and then this still occurs. The spam messages are not actually delivered to other people. The system still blocks the spam messages, but the spammer does try to send them and then my server maxes out the amount of allowed emails sent which is 1000 in my case.
