Outgoing Email Sending Limits

This page explains the Outgoing Email Sending Limits screen in GoAdmio. It controls how much email the server, each domain, and each user can send — and throttles the overall sending rate to protect the server's reputation and mail queue.

Location: Admin Panel → Security → Outgoing Email Sending Limits


Overview

Uncontrolled outbound email is one of the biggest risks in shared hosting. A single compromised mailbox can:

  • Blacklist the server's IP — blocking email for every customer for days or weeks
  • Fill the mail queue — delaying legitimate email for everyone
  • Trigger abuse complaints — from recipients and anti-spam services
  • Damage the provider's reputation — reducing deliverability across all accounts
The Outgoing Email Sending Limits page lets you set layered caps on outbound volume:

| Layer | Controls |
|---|---|
| Server | Total email the server can send per day |
| External IPs | Email sent from specific IPs (for multi-IP servers) |
| Domain | Email sent from each domain per day |
| User | Email sent by each mailbox per hour |
| Inter-Message Delay | Minimum time between messages, server-wide |
| Queue Alerts | Notify when the outbound queue exceeds a threshold |

> Note: This page is the detailed per-domain and per-user limit configuration. The Spammers page covers higher-level spam detection and server-wide throttling. Use both together for defense in depth.


What the Page Shows

Global Settings

| Field | Description | Default |
|---|---|---|
| MyNetworks | Trusted IPs or networks exempt from rate limits (space-separated). Typically the server's own IPs. | — |
| Server Rate Limit | Total emails the server can send per day | 15000 |
| External IPs Rate Limit | Emails per day from external IPs (0 = unlimited) | 15000 |
| Domain Rate Limit | Default per-domain daily limit (0 = unlimited) | 15000 |
| User Rate Limit | Default per-user hourly limit (0 = unlimited) | 15000 |
| Inter-Message Delay | Minimum delay between messages, per second (0 = no delay) | 0 |

Per-Domain Table

| Column | Description |
|---|---|
| Domain | The domain being limited |
| Domain Limit / Emails Day | Daily cap for this domain |
| User Limit / Emails Hour | Hourly cap for each user under this domain |
| Custom Rate Limiting | Whether this domain has a custom limit or inherits the global default |

> Tip: The Custom Rate Limiting column tells you at a glance which domains have overrides. Domains without a custom limit use the Domain Rate Limit and User Rate Limit global defaults.


Global Settings Explained

MyNetworks

A space-separated list of trusted IPs or CIDR ranges that are exempt from rate limits. This is typically:

  • The server's own IP addresses
  • Localhost (127.0.0.1)
  • Internal networks (10.0.0.0/8, 192.168.0.0/16)
  • Known transactional email systems you control
