Who are we? What do we do?
We are a subsidiary of Host Collective Inc., that specializes in providing white label (unbranded) email services.
Currently we host email services for over 20,000 unique domain names and customers between our new mail infrastructure and our legacy systems.
You can observe the size and volume of our mail traffic at our senderbase page.
How do I report Spam or Abuse complaints for mail from your servers?
You can report acts of Abuse, UBE/UCE (Spam) to our abuse email address listed at the top of the page in the contact addresses box. Please provide a copy of the offending messages so that we can properly trace and track it's source. We accept munged headers and messages, but might need to to request further details to resolve some complaints. Please send complaints un-munged if possible.
How can I contact someone at internetmailserver.net?
For general questions or inquiries to the internetmailserver.net network you should contact the postmaster email address listed at the top of the page in the contact addresses box. You should not submit complaints of abuse or spam to this address, please the abuse address for this.
What is your policy on relaying email for customers?
For specific answers on our policies for handling mailings on the behalf of customers please see the section below "Internet Mail Server Networks Policies".
We allow customers to relay messages for personal communication via email. We are not a mailing service provider, as such we are very stringent on the use of our services for sending mass or bulk mailings. If customers are found to be sending abusive or unsolicited mails in large volumes we follow the policies stated on this website according to internal processes to rapidly resolve such problems.
In addition to the policies the new internetmailserver.net v2.0 services require the use of SMTP-AUTH for customers to relay messages. Customers that relay messages via SMTP-AUTH have their authentication credentials and source IP address noted in the headers of messages they send. This allows us to effectively track potential sources of abuse back to the customers that generate them. On the legacy internetmailserver.net services we are not able to do this as effectively, though we have measures that allow us to track messages back to users if we receive complaints in a timely manner (within 24 hours). We are currently in the process of migrating all customers from the legacy services to the new v2.0 services. Once the migration is complete we will be able to easily track and respond to all complaints.
The internetmailserver.net mail servers are blocking my server, how do I resolve this?
Third-party block lists in use by internetmailserver.net.
- Spamhaus - SBL and XBL
- Distributed Sender Blackhole List - List
- Spam and Open Relay Blocking System - DUL
- Open Relay Database - Relays
SPF record checks
How to be removed from block lists in use by internetmailserver.net.
The internetmailserver.net infrastructure subscribes to a selected list of third party block lists. We do not manage these lists and are not able to remove you from such lists if you are blocked. Our mail systems will bounce messages that blocked via a block list with a 5xx error code and a URL directing you to specific information for the block. We recommend you resolve these issues directly with the block list provider before requesting a specific white listing from our services.
Proper PTR RR (Reverse DNS requirements).
We have just added a new restriction to the internetmailserver.net v2.0 services that denies inbound messages from systems lacking proper PTR RR records (Reverse DNS). Lack of PTR RR records is highly suspect for a legitimate mail host following best practices for sending mails. The majority of reputable dial-up and broadband connections provide PTR RR records for their networks. If you administer a mail server that does not have PTR RR records set for your mail server you will receive a 553 error message and warning that your reverse records could not be found. We will not white list senders of this requirement, senders should setup proper PTR RR records, or contact their upstream provider to do so for them if they do not have authority over their in-addr.arpa zone.
