Hi friends, there are some spam mails being generated from one of the server I look after. All passwords etc. have been changed but still mails are there.
This is one of the bounce mail from mail queue: http://pastebin.com/Ti052s22
ubbdi.net is the name of the domain , honore209@ubbdi.net is the user which is trying to send this but there is no such user on server.
This one is another one in mail queue: http://pastebin.com/ETaki4vx
Here domain is uddsolutions.com
Since accounts have hourly mail limit, there is no visible issue, only issue is that client is not able to send mail.
Can anyone help me to understand both above mails like source, how they are generated and what kind of issue could be there..
