Reseller & Web Hosting Email Mailing Lists - Policy

[tomp]

How much email can I send through my Myriad Network account?

Generally speaking if all you're doing is communicating back and forth between business associates, friends, family etc you will not run into issues.

On the other hand if you're sending high volumes of email through a mailing list please read the following:

1. Each cpanel account can send a maximum of 1000 emails per day.

2. Each cpanel account can send a maximum of 20 emails per minute.

3. All mailing lists must strictly conform to the policies outlined in the Myriad Network Acceptable Use Policy (AUP) available here - http://www.myriadnetwork.com/legal/aup.php

*If you exceed the limits specified above, your email(s) will be returned to you as undeliverable.

We had to put this policy in place as a result of a few customers sending 10 - 30K emails all at one time. This can seriously degrade the performance of our shared hosting platforms and impact our customer's ability to send and receive email during that time.

If you have a high volume mailing list please consider our Virtual Dedicated Servers (VDS) (http://www.myriadnetwork.com/services/vds.php) or email sales at myriadnetwork.com for more information on our available dedicated server solutions.

Thanks!

save yourself the hassle, get tracking and improve deliverability. email hosting only 19.95/mo. No i do not work for listcast, i am just a satisfied user.

Hi Cayley,

I have recommended email hosting to several others in the past as well, specifically those customers with very high volume mail lists (thousands of recipients that need to receive email often). I do agree that it's a nice complement to our webhosting and reseller accounts if you don't have the knowledge or experience to manage a VDS server (http://www.myriadnetwork.com/services/vds_moreinfo.php), or don't need something as high end as a dedicated server (http://www.myriadnetwork.com/forum/showthread.php?t=150).

For those with Linux systems administration experience, I don't really see it as much of a hassle as full control with root access is granted on those servers. As such, users are free to create their own configuration, modify an existing one, or however else they choose. We do currently allow 3 times the amount of email per month than the $19.95 plan that listcast offers (although we do have time based limits to ensure a stable and effective environment for all our users on each server), and I'm pretty sure our deliverability is just as good as theirs. For one, we don't have to fight to stay off of blacklists for several reasons:

1. We have a solid fraud checking system in place on all orders,
2. We are intimately familiar with techniques spammers use and have checks in place to stop them, and
3. We have a few custom things exclusive to Myriad Network that alert us to unwanted activity on our network (details intentionally withheld :) )

Glancing at the Exim stats ( /usr/sbin/eximstats -t_remote_users /var/log/exim_mainlog ) for the past 2 days, I can confidently tell anyone that our servers send and receive many thousands of emails per day without issue and in a timely fashion.

Surely that's an error. That would mean that a cPanel account hosting the mail of a company with 100 mail users would let only 20% of them send mail an any one minute. The other 80% would not only be blocked, but have no way of knowing this until they found their outgoing mail rejected.

Hi chrisjj,

It's always good to see non customers posting.

To clarify, each cPanel email account is restricted to the limits mentioned in the original post.

[chrisjj]

Thanks for the clarification Jeff.

What exactly do the stated limits (1000/day, 20/minute) apply to?

According to Jeff,

each cPanel email account is restricted to the limits mentioned

If, for example, there are 50 e-mail accounts for a given domain, do the stated limits mean that every single one of the 50 e-mail accounts can send up to 20 e-mails per minute, but the total cap for all accounts is 1000/day?

Second question: the original post refers to mailing lists, not individual e-mail accounts, but judging by the follow up, my impression is that the caps apply to the total number of e-mails sent, no matter "who" sends it: mailing list tools like MailMan or phpList, or individual e-mail accounts. IOW: do you monitor SMTP engine usage on a per-user and per-day basis?

So, far I haven't run into any problems with those caps, but I want to ensure that the mailing list tool that I installed for one of my clients (Dadamail) is able to deliver the message to 100% of the list subscribers. So far, the list is fairly small - about 60 subscribers - but as the script is pretty "snappy", I'm sure it sends out more than 20 messages per minute.

Is it possible that your SMTP engine simply accepts the message for all 60+ recipients from the script and then sends out 20/minute until all have been sent?

Some clarification here would be appreciated.

(BTW: no messages have been sent for a while via the script I mentioned -Dadamail -, but I'd like to understand the underlying "mechanics" and how your caps affect the operation of this script and others.)

Hi David,

Please see my comments below, thanks.

Correct. For example, let's say you have the following 3 email accounts:

david1@example.com
david2@example.com
david3@example.com

Each one of those can send up to 20 emails per minute, and each account can send up to 1000 emails per day.

Expanding on that: we currently are not enforcing the 20 emails per minute on the mailserver itself. If you send 21 emails in 1 minute, all 21 emails will successfully be sent, and no one will mind. We really like to allow our customers to be able to run their businesses as freely as possible without having to spend time learning rules and policies. It IS, however, policy to send no more than 20 emails per minute.

However, there is a restriction imposed by the mailserver itself for the 1,000 emails per day limit. What will happen is the emails will not be allowed to be sent through the mailserver.

This is done only to ensure a stable environment for everyone, as everyone needs to be able to get their fair share of the available resources.

Answered in my previous reply just above this one, but to clarify: it is on a per email account basis. It doesn't matter how the email is sent - it could be via a mailing list or an individual rapidly sending out emails through their mail client.



So, far I haven't run into any problems with those caps, but I want to ensure that the mailing list tool that I installed for one of my clients (Dadamail) is able to deliver the message to 100% of the list subscribers.

This is likely possible to do via a configuration on the mailserver itself, but again, we're not so much interested in strictly enforcing a 20 emails per minute limit as we are providing a stable environment for all of our customers. If your script is found to cause stability issues due to how quickly it sends, we have things in place on the servers to notify us of stability issues, and if it were an issue we would contact you. I would like to add that most mailing list software includes a built in, configurable control to rate limit how quickly email is sent. I am not familiar with Dadamail, but you may want to check with the vendor, FAQ, config files, etc to see if this option is available.

Please let me know if this answers all of your questions, thanks.

Hi Jeff,

thanks for the clarification.

I have one follow-up question. I might be dropping Dadamail in favor of phpList which can be conveniently installed via Fantastico. (Great script selection on your servers, BTW! Thanks for that.)

Do you have any configuration tips for phpList to reduce the server load in the case of a larger mailing (say: several hundred messages)?

Thanks again for your always excellent support!

David

Jeff,

I couldn't have wished for a better answer. Spot-on! :)
