Hi, I got this email from Ionos (1and1) support today, telling me I'm using TLS 1.0 or 1.1 for 2 of my email boxes (but not a third). Is The Bat! v 10.0.10 using TLS 1.2? If it uses TLS 1.2 then it's possible another email program (e.g. on my phone) is triggering this and I'll keep looking. I can't find anything in the documentation that says what version TLS it is.
TLS 1.2 has been supported since The Bat v8.5. Are you sure that you are using TLS or STARTTLS connection types in Account Properties | Transport for sending and receiving mail?
There are some command line parameters that can be used in relation to TLS, but none are usually required.
I volunteer as a moderator to help keep the forum tidy. I do not work for Ritlabs SRL.
Yes, TLS and port 995 and it's working. I wonder if my old computer with TB! v7.x is still accessing. That might be what's triggering this (or it could be some app on my phone, though I'd assume they all support TLS 1.2 if they're current).
Thanks for the quick reply. I'll move on and check other devices accessing these accounts.
