Q: Webmail auth from internet fails but from internal LAN ok - bug or feature ?
Hello Friends
I set up my Lion Server (10.7.1) as Mail-server, all works fine (IMAP, sending, receive Mails) except webmail.
The strange thing is that webmail is working fine if I connect from my intranet (internal LAN) to the server via: "http://<ip or DNS-Name>/webmail/"
BUT - If I try to connect from the internet via "http://www.blabla.com/webmail/" - I get the normal authentication page, but after typing in the credentials, and press the login button, I have to wait much longer, the wheel is spinning and the error message "could not connec to IMAP server" appears.
Questions:
- any tip ?
- How can I debug the communication between roundecube and IMAP server ?
- bug or feature ?
I don't think that roundecube distinguish between public and private IP addresses, but beside this, I have no answer to explain this behavior...
Setup:
Internet ---- FW ---- Intranet
- FW is doing NAT
- Mail-Server is on a DMZ
- Mail-Server has a static, private IP address
Many thanks for your inputs
Daniel
