Limits
There is a
500 outgoing email hourly 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 an undeliverable error. If this occurs, it
will then take some time for your account to be able to send again so we
recommend waiting at least 1 hour after this issue occurs to begin sending
email again.
Many of our
servers have a limit of 30 POP3/IMAP checks per hour per IP address. If
you go over this you're likely to get a wrong password error message or an
error stating "login incorrect". If this occurs, please wait an hour and
it will automatically unblock you. To prevent this from happening again,
please make sure to disable auto checking or at least set it to something
higher such as once every 10 minutes.
Any mailing
list larger than 5,000 addresses 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
1. Any time you're sending a message no matter how large your e-mail list
is you must throttle it. We recommend you throttle it to at the very least
sending 1 email every 8 seconds. (Sending 1 every 8 seconds would send 450
emails within 1 hour, keeping you below the 500 outgoing email limit.) If
the mailing list software you're using does not allow you to throttle you
must switch to an application or script that will. We recommend PHPList,
which can be found in your CPanel under Fantastico.
IMPORTANT:
If you do not throttle and you try sending 500 emails, the server will try
sending all 500 in 1 second which is not possible on our shared servers.
This will cause a very high load on the server and the entire server will
be sluggish, potentially affecting your sites and service, until this
sending process is completed. It is our job to keep the server up and
running without being sluggish or experiencing issues. Anyone who causes
the server's load to go high will be suspended and the process will be
terminated. If you choose not to throttle, you will most likely be
suspended for crashing the server.
2. Any
mailing list over 900 email addresses is only allowed to be sent to during
off-peak times to prevent high server loads. Off peak times qualify as all
day Saturday and Sunday, and 1AM - 8AM Eastern Standard Time, Monday
through Friday.
3. The list
must be a Double Opt-In list. This means a user has subscribed for a
newsletter or other email marketing messages by explicitly requesting it
and confirming the email address to be their own. Confirmation is usually
done by responding to a notification/confirmation email sent to the email
address the end user specified. The double opt-in method eliminates the
chance of abuse where somebody submits someone else's email address
without their knowledge and against their will. You will not be permitted
to mail any mailing list that you were given or purchased. In doing so,
this will also be considered spamming and may result in termination of the
offending account.
4. Any
unsolicited e-mail being sent will result in suspension or termination of
the offending account. We take a zero tolerance stance against sending of
unsolicited e-mail and other forms of spam.
5. Any
mailling list MUST comply with all guidelines set forth by the United
States government. These can be found at:

6. No direct SMTP mailers are
allowed. An example of this would be a Darkmailer or The Bat!. Any mail
should be sent through the local mail server/MTA for further delivery by
the server and not done directly by scripts.
