I have several email accounts at one address on the morrispaint.com domain. One of them is consistently having issues with IMAP through Thuderbird. orders@morrispaint.com gives me an "imap.zoho.com has disconnected" error. It seems like I can only access it on one computer at a time. If I open an email client on any other computer I get this error message. It's only affecting the one account. Cached connections have been set to 1 in all instances of Thunderbird that access the account, which is 4 total. I've had the error move from one computer to another while opening and closing Thunderbird to try and figure out the issue. Two phones are also regularly connecting to the account.
