What to include
- Your org id and app id. The dashboard's Support page fills them in.
- The static IP and region involved.
- The destination host and port, and what you expected to happen.
- The time it happened, with the time zone, and whether it still happens.

Report abuse
If traffic from a Fixedmark IP attacked, scraped, or spammed you, mail abuse@fixedmark.com with the source IP, the destination, the time with its time zone, and any log lines you can share. We act on the account behind the address. Scraping, rotating-proxy use, spam, and attacks on third parties are not allowed on Fixedmark.
Outbound mail
Port 25 is blocked on Oracle Cloud (OCI), Vultr, and Linode, the three clouds Fixedmark runs on, so the proxy refuses connections to port 25 with smtp_blocked_by_provider. Linode may also block ports 465 and 587 on new accounts. Use your mail provider's HTTPS API to send mail. If you need port 25, mail support: we ask the provider to open it for your region, and it opens only if they agree.
- Oracle Cloud (OCI): port 25 blocked. Oracle Cloud release note: outbound port 25 is blocked for tenancies created after June 23, 2021
- Vultr: port 25 blocked. Vultr: why is SMTP blocked?
- Linode: ports 25, 465, and 587 may be blocked. Akamai cloud computing: send email (ports 25, 465, and 587 restricted on some new accounts)
