The StackCP mail platform has several limits in place in order to protect the
reputation of the mail platform and prevent large quantities of spam
emails being sent.
New Mailbox Limit
When a new mailbox has been set up, the sending is limited to 50 per day for 7 days. This is a common practise to prevent new mailboxes being set up and used immediately to send out high volumes of spam emails. To preserve the platforms reputation and protect mail being sent from being spoofed as spam by third parties this rule was put place to protect that status.
Sending mail using Mailboxes:
After the mailbox is older than 7 days, it will be able to send a maximum of 8,000 messages per e-mail address per 24 hours.
Autoresponders
An autoresponder only sends once every 8 hours per sender.
Sending mail using Web servers
A limit of 500 messages per day is imposed on all e-mail sent by our web servers. This applies to all messages sent via the PHP mail() function. The total email size should not exceed 5MB in size.
