Is Port 25 available?
Yes. EDIS Global permits SMTP traffic on TCP Port 25, subject to the following controls:
The outbound rate limit is 8 packets per second (pps), with an initial burst of up to 16 packets.
The effective date is based on the creation date of the individual VPS, not
the creation date of your customer account. VPS instances created before February
24, 2025 are not subject to this automatic default rate limit. Our
Acceptable Use Policy and anti-abuse controls apply to every VPS.
Why outbound Port 25 is rate-limited
The rate limit helps EDIS Global:- Protect the reputation of its IP address ranges
- Reduce unsolicited email and compromised-server abuse
- Preserve reliable email delivery for legitimate users
- Respond quickly to abuse while keeping Port 25 available for normal use
Can the outbound rate limit be removed?
The outbound Port 25 rate limit is not a standard paid add-on, and removal is not generally available. EDIS Global may, at its sole discretion, approve an exception for an established and verifiable business operating a legitimate, consent-based email service. Contact EDIS Global Support before beginning such activity. As part of the review, we may request:- The legal business name and responsible contact person
- A public website and verifiable business presence
- The sending domains and a detailed description of the use case
- Expected sending and recipient volumes
- An explanation of how recipients provide consent
- Unsubscribe, suppression, bounce, and complaint-handling procedures
- A working abuse contact
- Correct rDNS, SPF, DKIM, and DMARC configuration
- Confirmation that the VPS is not operating as an open relay
What happens if spam is reported?
EDIS Global may immediately block outbound TCP Port 25 for the entire VPS if a credible complaint or other evidence indicates that unsolicited email was sent from any IP address assigned to that VPS. The block applies to all IPv4 and IPv6 addresses assigned to the VPS, even if the complaint concerns only one IP address. Inbound TCP Port 25 remains unaffected. A single substantiated complaint may be sufficient. You must promptly:- Investigate and stop the reported activity
- Secure any compromised accounts, credentials, applications, or software
- Address the cause of the incident
- Respond to EDIS Global with the remediation taken
