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.

what happens to the emails sent in excess of "The maximum each domain can send out per hour" limit that you can set in root WHM?
Are they discarded or get queued up in Exim?

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. ]

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

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?

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.

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.

cPanel server with EXIM.
Seems the standard feature there - number of emails per hour limit is not working in this case of script emailing.
Any way to limit the number of emails sent via .php scripts or/and throttle this emailing speed cause in the case of spamer the server load hit the roof.

I have a plesk 12 panel with outgoing email limit configured to 10 messages by hour.
I have a redirect account (An account named for example A, without mailbox, doing forward to another two internal accounts B and C). I doesn't know if these account are in use for outgoing email, but i think no.
The problem, are, these account are triggering the outgoing limit everyday on some hours. What's going on? Maybe the forwarding action are counting outgoing emails?
I need some method to check account when they trigger the limit to view who messages are trying to send (At least, headers, because i doesn't understand who messages are triggering limit). Also, if the problem are the forwarding, i need a method to not count these messages as outgoing ones, because i understand, if forwarding are triggered by an automated action / internal redirect / received message, these message doesn't are a outgoing one.

The 'Additional Administrator Accounts' feature enables a Plesk login to be created for each administrator, so they don't have to share a login, which is good practice.
However, Plesk sends notification emails (e.g. Notification of problem domains) to all the administrators. How can we control who is sent notification emails? In our case, we only want them to go the main admin account.
In the 'Additional Administrator Accounts' form, the 'email' field requires a value. We could set this to a dummy value, but this would probably generate non-delivery emails.

Only one domain suddenly out of the blue is not receiving emails via web or pop3.
- deleted / recreated email
- eximup forced
- domain exists in trueuserdomains, localdomains but not in remotedomains (shouldn't)
- restarted pop server
Mail works fine on the various other domains on this box
cpanel/centos
What could be the cause? Site works fine, made no server edits.
EXIM logs show this for example
2008-01-03 20:20:03 [1643] 1JAcAE-0000QS-Ly ** admin@domain.com F=<root@server.hostdomain.com> P=<root@server.hostdomain.com> R=lookuphost T=remote_smtp: SMTP error from remote mail server after RCPT TO:<admin@domain.com>: host sentry.domainbank.com [64.85.73.28]: 553 sorry, that domain isn't in my list of allowed rcpthosts (#5.7.1) .......

when I ask a hosting company to take over the domain and hosting of another supplier, what happens with the emails during the transfer ? If the client has his mails set up at his current hosting, how does the new hosting accept the mails once it is transfered? Will there be a period when no emails arrive? And do we lose them?

I can get emails to admin@mydomain.com, but i really wanted to alias it so emails to admin@www.mydomain.com go to the same account. MX records for www.mydomain.com and mydomain.com both go to mail.domain.com. .
This is on a dedicated server, centos, with exim doing the email handling.
I was thinking maybe it would be like an alias of some sort, or somewhere to put a list of combinations i can accept email for.

We are only a small construction business in NEW Zealand, and send very few emails. But from the 4th April, Yahooo has started blocking all emails from our domain name?
We hve not done bulk newsletters, we have not had bulk reject messages. Our website/ email host is Clevernet.
YAhoo NZ have sent us a bulk email form, which Clevernet submitted. We then had to get another approved server form filled out by Cleverney which they did last Friday, but our email domain is still blocked.
Xtra/ Yahoo NZ< seem to think there is nothing they can do, but wait and see if Yahoo unblock it. There does not seem to be anyone who we can contact at the Yahoo server. NZ say they cant contact anyone at Yahoo. We seem to be stuck between a rock and a hard place.

A customer asked me if it could be possible to disallow certain email accounts to send emails out of the accounts domain. Is there a way to do so with the Exim installation in Cpanel?
