Not a K-9 Mail problem, but I'm stumped where else to ask. If I am at home, I cannot connect to my work e-mail server if connected via WiFi (Verizon FiOS). (A CentOS-based server running Apache httpd, sendmail, dovecot, etc. but, as you'll read below, I don't think it is relevant.) If I turn off WiFi, and use the Verizon 4G service, I have no problem. If I go elsewhere and connect via WiFi, no problem.
This is with K-9 Mail on a Galaxy Note II (stock OS, not rooted or anything), but is not just K-9 Mail. I cannot open the web mail interface on that same server using the web browser on the phone either. But I can connect to any other server in the office, including a secondary web mail server on the same physical network and IP subnet as the main mail server. To add to the strangeness, other devices on my home WiFi network have no problem accessing the mail server that the Galaxy Note II will not connect to. This includes Apple Mail & Safari on an iPad and Thunderbird & multiple web browsers on a MacBook Pro, and both Chrome and K-9 Mail on an Asus Nexus 7 tablet. Since the home network is NAT'ed by the FiOS router, all devices are connecting to the Internet using the same single public IP address. I have verified there are no outbound firewall rules on the FiOS router and no relevant firewall rules on the office side either. Unfortunately, as far as I can tell, Samsung disabled something on the Galaxy Note II so I cannot use any of the traceroute tools I've found in the Play Store unless I root the device. Not sure what other network troubleshooting tools I can use to gather more clues. And so I am stumped. Why can't this one device connect to this one server when everything else on the same network has no problems? Thanks in advance for your insights. -- -- You received this message because you are subscribed to the K-9 Mail Users List.
