[Bug 997913] Re: thunderbird fails to connect to mail server

[Wolf Rogner]

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.
