I've had a few issues recently. Firstly Thursday last week got a notice today using Thunderbird email client that there is a security issue - this had not appeared ever before. I was getting the screen messages as attached (These need to be looked at in 1,3,2 order) The web hosting service provider advised that any mail clients should connect without a secure connection (SSL). I've checked my Thunderbird setup and changed to SSL as it was set to STARTTTLS. Note I've been using Thunderbird successfully for more than 6 months with the same email address and web host and have not changed any setup myself from the first time I used it - so can only assume if STARTTTLS is wrong then something in Thunderbird has changed it itself??? Now tonight I see all emails in inbox earlier than 14/03/15 are gone? Sorry for posting 2 issues in one message, but think thy could be related?? I am certainly not tech literate so hopefully get this sorted withe some help here.
