Our email policy allows us to fight spam, prevent abuse and provide fair and reliable web hosting to all DomainsFoundry members.
These limits are above industry standard and are designed to comply with email standards and industry best-practice.
The following limits apply to all email accounts hosted on our shared web hosting servers.
- You can send a message up to 100 people at a time.
- You can send up to 500 emails per hour, per domain on all shared hosting servers. This limit also applies to mailing lists and emails sent from your website. If you exceed this amount, your emails will not be sent and will be bounced-back to you. This limit does not apply if you use your ISP’s SMTP.
- You can send and receive email messages up to 25 megabytes (MB) in size. If you send a large email to your contacted hosted with another email service, it maybe rejected for exceeding their smaller email size limit. If your attachment bounces, you should invite them to DomainsFoundry.
- 30 POP3/IMAP checks per hour, per IP address. If you go over this your account will be locked for 1 hour and you may see a failed login message when you try to reconnect. Your account will be re-enabled after 1 hour. To prevent your email application from locking you out, disable automatic sending and receiving or set it to only check every 10 minutes. The limit is per IP address so if you have a number of computers checking email on the same IP address you will need to adjust the checking frequency accordingly.
- You can have up to 5,000 addresses across all of your mailing lists. For example you can have two individual mailing lists each with 2,500 addresses, or a single mailing list with 5,000 addresses. But not both. Dividing a large list into smaller lists to get around this limit is not allowed. Large mailing lists cause high server loads so if you require more than 5,000 addresses than you’ll need to upgrade to one of our dedicated server solutions.
- Your email account may only be used to store email message. It is designed to manage email and should not be used as an ‘online drive’ or ‘dropbox’. If you need to save files online you can use the file manager tool in your control panel.
There are no limits to the number of emails, senders, mailing lists or addresses on our dedicated server solutions.
Mailing List Rules
- Every email list, regardless of size, must be throttled to at least 1 email every 8 seconds. Keeping you below the 500 outgoing emails per hour limit. If your email app/script does not allow you to throttle the number of emails per second, then you must switch to one that does. PHPlist is a mailing list application that supports throttling out of the box. See [[How to install PHPlist]].It is very important that you limit the rate (throttle) outgoing emails sent from your mailing list application, or script to a maximum of 1 email every 8 seconds. If you do not throttle, your account will send all your emails in 1 second, putting a massive load on the server. You risk crashing your own site and taking the server offline. Of course, we monitor our system around the clock to ensure this never happens. If you attempt to send your mailing list without first throttling the outgoing email to 500 per hour, your account will be suspended for high-CPU usage.
- Mailing lists greater than 900 addresses must be sent during off-peak. This allows us to balance out the server loads and prevent CPU spikes. Off peak times are all day Saturday and Sunday, and between 12AM – 7AM GMT, Monday through Friday.
- Your list must be a Double Opt-In list. WikiPedia – Opt-in email. You are not permitted to mail any mailing list that you have purchased or been given. If you do, we consider this to be sending spam email and may result in the termination of your account.
- We operate a zero-tolerance policy against the sending of spam and unsolicited email. If you attempt to send spam or unsolicited email using a mailing list, we will immediately suspend and terminate your account.
- All mailing lists must comply with The Privacy and Electronic Communications Regulations.
- The use of standalone SMTP mailers such as Blat! are not allowed. Any outgoing email that passes through our systems must be sent by our local mailserver/MTA. Use of such a program will result in your account being closed.
