Limits

There is a 200 hourly email limit per domain this limit is also applied towards mailman. If you send over this amount in any hour most of the e-mails will bounce back with a undeliverable error.

Many of our servers have a 60 pop checks per hour limit per domain. If you go over this you're likely to get a wrong password error message saying login incorrect. Just wait an hour and it will automatically unlock you. to prevent this from happening again make sure to disable auto checking or at least set it to something higher such as 5 minutes.

Any mailing list larger than 2,500 will require a dedicated hosting solution from us. Note: dividing one large list into smaller lists to get below this limit is not allowed.

Mailing Lists Rules

Anytime you're sending a message no matter how large your e-mail list is you must throttle it. We recommend you throttle it to no faster than sending 1 email every 6 seconds.

If the mailing list software you're using does not allow you to throttle you must switch to something else.

You are not allowed to mail to a mailing list you were given or purchased.

Any unsolicited e-mail being sent will result in termination of the offending account. We take a zero tolerance stance against sending of unsolicited e-mail.

Any mailling list MUST comply with all guidelines set forth by the United States. http://business.ftc.gov/documents/bus61-can-spam-act-compliance-guide-business

No Direct SMTP mailers are allowed. An example of this is DarkMailer.

Any mail should be relayed through the local MTA (localhost:25) for further delivery by the server and not done directly by scripts.

Default cPanel Accounts / Catch-Alls

The default mail account created with cPanel may be emptied daily. The default account is a receive-only account and is not capable of sending mail. Often this default mailbox is ignored resulting in hundreds of thousands of emails from scripts filling this box and never being manually emptied. Should you require a catch-all, please create a regular email account in your cPanel under "Email Accounts" and then set that email address as the default (catch-all) under the option "Default Address."
