TLS 1.0/1.1 deprecated in 03/2021. Wouldja disable them on SMTP/MTA by 08/2026 and not lose emails?
TLS 1.0 and 1.1 were officially declared deprecated by the IETF in March 2021.
Google's Gmail still supports TLS 1.0, 1.1 and 3DES (outbound only) for compatibility with legacy systems.
If you ask a lot of seasoned admins, TLS 1.0 looks dead for email, TLS 1.1 is mostly used by scanners and spammers, with some real traffic, but rare. How does everyone feel about removing receive/send support for everything lower than TLS 1.2 currently.
I understand we have enough room to do best TLS magic with IMAPS/submissions or webmail, but when it comes to SMTP/MTA, there is always this feeling to continue to allow TLS 1.0/1.1 for now until the big ESPs start dropping support.
Dear Email Hosting providers:
How many emails have you received/sent with TLS 1.0/1.1 on SMTP/MTA over the period of past 12 months? This will help assess the risk of disabling TLS 1.0/1.1 by August 2026.
What are your thoughts?
Thank you!
