Hi I have a Virgin.net email account. I use MailWasher to check my emails & delete unwanted/spam messages. I then open Thunderbird. Some messages that I want to keep are visible in MailWasher but not Thunderbird. I can also access emails by my phone or Virgin webmail - the emails are missing there too. MailWasher checks for new emails frequently and, I assume, deletes those messages which are not visible in Thunderbird on the next check. I have checked all folders in Thunderbird and webmail including Deleted, Spam/Junk and the missing emails are not there. This is a new issue, only happening over the last few days. Is it possible for Thunderbird to delete messages without my knowledge and without sending them to Deleted/Junk?
