   • investigating15 Oct, 16:04

     **2026-10-15T15:03:38.655Z** — The team recently updated how our servers process traffic. Specifically, SMTP (https://www.rfc-editor.org/info/rfc5321/#section-2.3.8) requires 0x0d immediately before 0x0a; a recent patch to Exim against "SMTP smuggling" has altered its behavior when it encounters a missing 0x0d. The team is looking into rolling back this update, but in the meantime, we are suggesting connecting to 45.33.50.34, 43.228.184.6, or 45.33.53.153 instead of the mail.smtp2go.com hostname as a potential workaround.
