- wiml 3y agoSome Cisco routers have/had a feature where they'd mitm every smtp connection and snip out the STARTTLS advertisement to prevent negotiation of an encrypted connection. Of course this doesn't affect port 465 use, but port 25/587 can get silently downgraded.
- red_admiral 3y agoDo any major providers these days still allow unencrypted SMTP at all though? Seems like quite the security risk.
