I am using Ubuntu 12.04 LTS and Thunderbird 14 I have configured correctly all accounts using common Local folders I send and receive correctly emails. Suddenly, usually 4-5 hours after I switch the pc on, I can not send email but receive only. Other information is that it is a dual boot pc with Vista and both OS are using same profile folder.

Do you get any sort of error popup when a mail fails to send? – Caesium Aug 3 '12 at 11:30
yes, standard email smtp server failure dialog box. some times sending stops at 88%, other times in less – bob Aug 3 '12 at 14:08
one day before the first day I noticed it, I have installed only cifs-utils. And also I remember I had at the same time problems in Firefox (saving web forms). I do not know if they are related however. strange? – bob Aug 3 '12 at 14:25
it happened again, after 4-5h since last power on (it is reproducible). – bob Aug 3 '12 at 14:55
Sending of message failed. The message could not be sent because the connection to SMTP server mail.xx.yy timed out. Try again or contact your network administrator. – bob Aug 3 '12 at 14:55

The problem I found out is generated every time dmesg.log is updated. Solution is to reset wireless connection. It is generally not only Thunderbird but sending out network connection problem.
