Hey all,
I'm getting a fault in dovecot (see below) using shared folders. I have a mailbox that receives new mail (Account X/INBOX). Another account (Account A) has access to the other account (Account X/INBOX) with ACL below.
The ACL directory (.DEFAULT) contains: user=AccountA lrwst
I removed a test email from Account A/INBOX, which is supposed to remove the email from Account X/INBOX. A fault occurs whenever my client (Thunderbird) attempts to connect and complete the deletion. Other actions complete successfully. It only appears to happen when using Thunderbird. Mac Mail does not cause the fault.
I'm not getting a core dump so all I have is what the log outputs. I can reproduce this regularly so let me know if you need any additional information.
Thanks,
JT
