Please add a way to limit the number of outgoing emails

New Pleskian
Please add new feature to limit the number of outgoing emails Yes this is a very bad that we cannot limit outgoing emails!

One of our hosting customers was a spammer. Because of their spamming our IP was blacklisted.

We removed the blacklist and suspended the spammer, but during that time our other customers were very upset, their emails weren't being received...and new customers of ours couldn't receive download letters sent from us, it was a terrible problem! Then they would complain but support tickets weren't received, either!

Parallels, please add a feature (like cPanel) where we can limit the number of emails any user can send in a day/hour/etc so we wont have this same problem again.

Thanks!
 
+100 for this feature. This should be a standard feature and not an extra paid for module .... period! :)
 
We signed up and configured the "Parallels Outbound Antispam". It's $3.99 US a month. Unfortunately, a few days later a NEW spammer signed up and sent hundreds of spam emails within the last 24 hours. Parallels Outbound Antispam did not work or help.

Again our hosting domain is on blacklists. Again our customers are upset because their emails are not being received. Again we must wait to be unblocked. This is terrible. I feel ripped off by having to pay for an add-on product that I dont want. Parallels Outbound Antispam product didnt even prevent the spammer. This is a ridiculous add-on.

PLEASE add a field where we can choose how many outbound emails we will allow a user. PLEASE ADD THIS FEATURE. We should be given the option to limit the number of emails our hosting customers can send in a day (or per hour, etc). That is good and simple and will solve so many problems for anyone trying to use Plesk for a hosting company. cPanel has this. Plesk should also have it. Please stop trying to milk us for more money with ridiculous add-ons to solve a feature that should already be there. This is terrible bad business. Thank you.
 
It is complicated - to limit a user you would need a way to identify a user who sent an email. Reliable identification is only available in SMTP sessions, while many spammers may send via locally running scripts. Identifying a user isn't easy in such case, but anyway, Plesk tentatively may have this ability in next version.

As we are experimenting with customer votes currently, you could vote for the feature at http://plesk.uservoice.com/forums/184549-general/suggestions/3539690-limit-outgoing-mail-messages. Filing other feature suggestions and voting is welcome as well.
 
cPanel is doing this for more then a year and I personally prefer cPanel because of more rich features. cPanel is limiting the emails per hour per domain, so, a feature like this on Plesk is more then welcome.

On a shared server with 1k+ accounts and un-updated Wordpress, Joomla etc apps, the hackers can hack the pages and send spam. Also, Plesk does not support sending emails from the clients dedicated IPs, all emails are sent from the main IP, so, now you can see the picture why this feature is important. Imagine 2-3-5K/emails per hour from one single IP, this can easily blacklisted.

So, push this feature to #1 and you will make new customers and more sysadmins happy ;)

There is no silver bullet solution to this and I'd really like to have more technical insights on what cPanel does here, I'm not using it. Limiting the number of messages or the amount of data sent via smtp is relatively easy with Postfix if you only permit relaying for authenticated users: use a policy service, that's what we do and gives good results. If you don't do the checks based on authenticated users, you can't reliably enforce limits since the sender address can easily be forged.
But on a shared server you have websites and most of these are configured to submit emails via the local sendmail wrapper. How can you enforce per user limits here? Based on what, the sender name, the domain name? Ideally in a shared environment the admin should forbid locally submitted emails unless they're coming from certain system uids (e.g. root), but this way you'll have many happy customers until they'll figure out they should use SMTP+auth for their mailers.
 
Hello,

On postfix we have options on main.cf like smtpd_limit_message_rate and other smtpd_limit rules to limit outgoing mails, but it does'nt work after postfix reload, view this topic :
http://forum.parallels.com/showthre...-to-reduce-spams-sending-when-main-cf-changed

So can you please Sergey or Igor fix this problem (with a microupdate) until that you finish your outgoing mail feautre for plesk. Our server was also blacklisted and our smtp port 25 blockd too.

thanks
 
This is actually so VITAL that I am really surprised that cpanel and directadmin have a way to limit outgoing emails in order to avoid spam while Plesk doesn't, really surprised!

Each email address should have its own limit of X emails sent per day that we could set when we create that email account and edit later. This way if one user started spamming from his account, once he reached the limit set for the day, one of two things whould happen instantly, depending which one we set for that email account in the settings:

a) the email address should be blocked for outgoing messages AND a notification message should be sent by the system to the system administrator as well as to the email address blocked, indicating that [email protected] email address has reached the limit of emails that could be send that day and has been blocked for outgoing messages.

b) the email address should not be blocked BUT a notification message should be sent by the system to the system administrator as well as to that email address itself, indicating that [email protected] email address has reached the limit of emails that could be send that day and that the matter should be checked.

This would be GOLD for server administrators, as we would be able to detect spam and handle way before it collapses our servers and our IPs go into the blacklists. INVALUABLE GOLD!
