Hello, Since yesterday evening - no config changes or change on server or network. Suddenly I got a few hundred mails with Mailsize: cus**_name in my mailbox. In the message-body there is only the size of the mail. When I set a forward on the another (external) account the mailsstorm stops. Back in the old situation (cust**_name ) I get lots of mail again. What happened and what is the solution. With kind regards, John L
Hi Falko, I think I found out the cause of the problem. In my case it has nothing to do with a forward in /etc/aliasses or new addresses. Nobody added new addresses in ISPConfig or aliasses. The only thing I changed friday evening was a DNS entry(before the mailstorm began). >> I made a wildcard entry for the main domain (* A ipddress). Yesterday morning I removed it and also the (internal - server) mailstorm was stopping slowly. Now 15:00 I don't get any customer_mailsize mails I hope removing the wildcard solved my problem. Wkr, John L
