From where did you run check-if-email-exists?
Self-hosted Docker on Advin VPS using reacherhq/commercial-license-trial:latest
Version of check-if-email-exists (if running it yourself)
reacherhq/commercial-license-trial:latest (v0.11.6)
What happened?
Summary
The built-in Proxy4Smtp SOCKS5 proxy is unreachable on port 1081. All email verifications return is_reachable: "unknown" with a SOCKS5 timeout error.
Error Message
{
"is_reachable": "unknown",
"smtp": {
"error": {
"type": "Socks5",
"message": "i/o error: Operation timed out (os error 110)"
}
}
}Investigation
I tested connectivity to all Proxy4Smtp IPs from multiple environments:
| IP | Ping | Port 1081 |
|---|---|---|
| 51.89.178.174 (default in Docker image) | Success | Timeout |
| 46.166.184.114 (from DNS) | Success | Timeout |
| 185.206.180.90 (from DNS) | Success | Timeout/Refused |
Tests were run from:
- My local machine (Archlinux)
- A VPS (Advin - verified ports 1080/1081 are NOT firewalled by provider)
