remove email from spam blacklist


my email domain has been on two spam blacklisted databases. I have requested removal couple of time but again we get in there. This has been affecting our business frequently.

I called up mxtoolbox and asked them for assistance but they asking for $600 per month which is very high

can anyone help me how to get these email domains removed from blacklists ?

current we are listed on blacklists on below 2 organizations

SORBS-SPAM       LISTED      Spam Received See: Detail

Fix your server so you don't send spam and you won't keep getting relisted.  But fix it BEFORE you ask to be delisted.  Many lists increase the minimum time that your IP remains listed if you are a repeat offender.

The SORBS-DUHL list is a listing of Dynamically assigned IP address blocks, so if you want to get off that list, it would suggest you are using a dynamic IP address, so if you can, get a fixed IP address.

The SORBS-SPAM list presumably means you are sending spam, or the previous temporary user of your IP sent spam.

Or you might want to send your email out using a Smarthost instead of DNS, speak to your ISP about this.

Also check your Server for viruses etc.
