Hi Patrick, 1. it is reproducable over several machines 2. After restarting server and client it works fine for some days, then appears and gets worse (in the beginning, restarting Thunderbird works, later not) 3. Evolution or any other mail client works fine (currently I check my mail with an iPad) 4. I run a Ubuntu server with bind and dhcpd 5. no VPN (which fails as well btw) 6. I do run a WiFi network (see IwConfig.txt above)
I have files a bug with network manager as thunderbird people suggested it be a network problem (which appeared to be the case) After a reboot my /run/nm-dns-dnsmasq.conf looks like this server=10.1.0.4 server=10.1.0.254 server=195.202.128.3 My /etc/resolv.conf like this # Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8) # DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN nameserver 127.0.0.1 search rsb.intern rsb.at After a while however (sometimes more than an hour) it looks like this # Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8) # DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN nameserver 10.1.0.4 nameserver 10.1.0.254 nameserver 195.202.128.3 search rsb.intern rsb.at I cannot reproduce this by calling resolvconf -u manually. If I try to simulate this by manually copying the correct name servers into /etc/resolv.conf, Thunderbird connects without any problems. Thus it seems to me that the new dnsmasq mechanism has not cought on to Thunderbird. I hope this helps you clearing the issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/997913 Title: thunderbird fails to connect to mail server To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thunderbird/+bug/997913/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
