How Many Emails Can Be Reasonably Sent Per Hour

May 16, 2007

I have a P4 2.8GHz Linux box with a Gig of RAM. How many emails per hour could I expect that this server can handle per hour? I would of course want that the server has enough horse power to handle visitors to the web sites.

This is sort of a followup to a previous thread that I started concerning the limit on # of emails per domain per hour. The box came with a [cPanel] default of 500 per hour. Can I expect for my server to be able to handle more than that? 1000? 2000? 10,000? Do I need a more powerful server? I hope not - I just don't have the budget.

[ FYI - The emails are legitimate and not spam. I am sending out email reminders of personal events and holidays to subscribers that enable this option. ]

Limiting PHP Emails Per Hour

Jul 29, 2009

On an cPanel + RHEL 5.3 box at WHM - Tweak Settings, I activated "The maximum each domain can send out per hour (0 is unlimited)" and set that value to "300".

But, it seems that this limit is only if the user is sending using webmail or an email client, right now a joomla website is sending much more than 300 mails per hour, but it's using php to send the mails.

My question, how can I limit emails per hour on each domain while sending from php?

29457 username 20 0 29724 13m 5848 R 10.2 0.2 0:00.10 /usr/bin/php /home/username/public_html/index.php

Setting Maximum Emails Per Hour In WHM

Sep 2, 2008

I know there's a option in the WHM that says "The maximum each domain can send out per hour (0 is unlimited" and it affects all the accounts under the same server, but, Is there any possibility to configure the WHM/cPanel to give different values to each client?

WHM Limit On # Of Emails Per Domain Per Hour

May 16, 2007

My server currently has 500 set for this parameter. However, I have some scripts that send out reminders and the number of emails will certainly exceed this limit. So this leads to some questions...

What will happen if my scripts try to send out more than the limit?

What happens when the limit is exceeded? Do the scripts "crash", or do they just keep running? Do the "over quota" emails just get discarded or do they get queued?

How does this affect performance? Or maybe it doesn't?

Does the email queue get clogged up if it has too many emails?

What could be bad about increasing the limit - say to 2000? Would this create performance problems for my server?

I have a couple sites that I'm hosting and I would prefer to keep the limit of 500.

However, how can I increase the limit for my own scripts (domains)?

Or, perhaps this option has nothing to do with performance and it's strictly in place as a security measure to prevent hosted accounts from spamming.

I searched for information concerning this issue and couldn't find anything. The cPanel/WHM forum doesn't say what the parameter is for, just how to set it.

Sendmail - SMTP Auth & Max Emails Per Hour

Apr 6, 2009

I have Cpanel, with the "Prevent Nobody from sending emails" in the WHM>Tweak Settings enabled.

I want to force sendmail to use SMPT auth.. so that all mails sent are sent via SMPT and an authenticated POP user.
I guess this will help in limiting the "The maximum each domain can send out per hour" setting.

Plesk 11.x / Windows :: Configure Quantity Of Outgoing Emails Permitted In An Hour Or Minutes

Aug 15, 2013

I will wanted to know if hmailserver lets configure the quantity of outgoing emails it is permitted in an hour or minutes. I have found this:

hMailServer is pre-configured to have high security when it comes to relaying and authentication so that no one can use your server to send spam messages.

But I do not know if It refers to what I want or to an antihack or something like that to protect my server.

Best Way To Send A Mass Emails

Dec 20, 2008

Every month or two, we like to send our members a newsletter-type email which just informs them about what's happening over in our website and community. We have over 350,000 accounts registered, so there's quite a few emails to be sent each time.

I'm currently using cPanel with Exim and SwiftMailer to send the members an email through PHP. The way I do it currently is import all the email addresses to a separate table then email 500-1000 at a time. This is controlled by a Cron job.

I'm finding Exim to be extremely slow and the queue has built up to 190,000 as I type this (the email process started last week).

My question is this. What's the best software, whether it be a program or a script of some form, to send an email to such amount of users? Or if anyone knows any way to 'tweak' Exim to handle such mass-emails.

To Send 3.6 Million Emails

Sep 22, 2007

to send 3.6 million emails over a week period of time. it is for a client that wants to send an email about their new account policies. these users are clients from different domains. how can this be done.

They have an exchange server onsite. should they use that server or do you recommend going through a service? if so whom do you recommend that is good?

Do you recommend going with a dedciated server for email? what server specs?
the email will not have an attachment just a few lines and a link to their own site.
with whatever solution you recommend? please give me price ranges?

Dell and such enterprise companies send emails all the time with that many emails and more to external clients... how do they do it.

I just do not want to get black listed and want to make sure all or most of they clients get it.

How To Make Exim Send Out Only Emails From Localdomains

May 16, 2009

I've looked through my exim logs a number of times and I see emails being sent out with "from:" fields with email addresses of other domains. Usually they are spam related and fraudulent.

How can exim be setup to only send out emails that have localdomains in their from fields?

E.g. if I have account on my server then the owner of can only send out emails "" no matter what else he tries to do that's all exim will send out.

How can you get exim to do this? I have been using filtering to block commonly spammed domains like etc - any emails sent out with these in their from fields are filtered and blocked - but rather building up a larger and larger filter of commonly abused domains - why not just block everything except domains on your server.

Plesk 12.x / Linux :: Sites Do Not Send Emails

Apr 30, 2015

Started after last update 12.0.18 Update #44 (on CloudLinux): I can send mail wia created mailboxes, but sites can not send mail, contact forms say "Failed to send your message." maillog file also do not indicate sending any messages from domains. Wordpress restore password claims:

"The e-mail could not be sent.
Possible reason: your host may have disabled the mail() function."
php.ini is default:
safe_mode = Off
disable_functions = is empty

The issue about not sending mail from domains was - old versions of LVE anf CageFS are incompatible with latest plesk update, updating them caused all sites in Cagefs to throw error 500 with log string: "SecureLVE jail error Invalid regexps: no match for path to base home directory". It was fixed by changing cagefs.base.home.dirs regexp to the real sites folder location. Enabling cagefs back removed one of the files it shouldn't:

"Removed file /var/cagefs/81/xxx/etc/php.d/soap.ini"
So be carefull to place necesssary files back.
For now everything works.
