Hello! I am using the latest version of Thunderbird for an Android phone. I use Bluemail for my website. Here is the issue: * Installation of the Thunderbird client is good. * Establishing a connection to my Bluemail email account is good. * IMAP works great. * The issue is email can be sent, BUT the email does not reach the recipient. There are no errors in the Thunderbird app at all. Mail does not get delivered. I have tried several external recipient email accounts. Now, the desktop app works great! So, the settings are the same. Any thoughts? Thank you.
