Hi, My system updated to TB 78.5.0 today on my Win 10 PC. Now I can't access my internal IMAP server. In the accouint settings I have set and use a simple "hostname" for my IMAP server which has worked for years. Now with thislatest release TB has decided to prepend "mail." to it and now searches for "mail.hostname" which fails. The IMAP server is running on a Linux box and name resolution on my network is via NetBIOS/NMB as I am not using a local DNS server for a variety of reasons mainly connected to my router's DHCP server. How can I force TB to do a name lookup on the enterd parameter of "hostname" and not "mail.hostname"? Thanks, Julian
