Testing #SMTP (EHLO/HELO) on a #Linux localhost (MTA/MUA) validates email flow. Use telnet localhost 25 or openssl s_client -connect localhost:587 -starttls smtp to initiate a session. Proper testing requires a FQDN (e.g., mail.example.com) rather than localhost to avoid spam rejections, as EHLO identifies the sending server.Essential SMTP Testing Commands

Reports of Telnetโ€™s Death Have Been Greatly Exaggerated

"We see no evidence that specific core network autonomous systems have
blocked Telnet, contrary to previous reports. We specifically see continued
non-spoofable Telnet traffic from networks on which GreyNoise saw 100%

2026-01-14: The Day the telnet Died

"On January 14, 2026, global telnet traffic observed by GreyNoise sensors fell off a cliff. A 59% sustained reduction, eighteen ASNs going completely silent, five countries vanishing from our data entirely. Six days later, CVE-2026-24061 dropped. Coincidence is one explanation."
