Thank you for taking the time to report this bug and helping to make Ubuntu better. Please answer these questions:

* Is this reproducible?
    - Try another email client (evolution, kmail) to make sure it isn't a server issue.
* If so, what specific steps should we take to recreate this bug? Specifically...
    - What server(s) did you try connecting to?
    - Any particularities with your connection? VPN? WiFi?

This will help us to find and resolve the problem.

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.

Setting status back to new, as reporter is able to reproduce the issue. (I do not personally have the resources to confirm...)

Still gets me in Xubuntu with Thunderbird 17.0.2. Sometimes it connects to YahooMail (via Imap), sometimes it doesnt!
