Hi
Maybe somebody could help me with the following problem:
I have set up a dovecot imap proxy in the dmz and a dovecot imap server in the intranet. Both in version 1.05.
Now, while this setup works using Thunderbird, iPhone, etc. I have problems connecting using a Samsung Qbowl. It simply aborts with a connection error.
Using the same setup but bypassing the proxy and connecting to the imap server directly does work for the phone.
Logs on both servers don't show any errors. There is simply a "Info: IMAP(test): Connection closed" at the end.
I enabled the rawlogs on the imap server but they don't long anything (They do log access from other imap clients but nothing from the phone).
Could somebody point me into a direction where to look next?
