My problem is: when sending EMails with Thunderbird, I often got timeouts from my GMX provider (something like “timeout from SMTP-Server”). When trying to send it once more, it mostly works. But it’s annoying to send most mails two or three times.
After switching the Avast-scan for outgoing mails OFF it works now. With the problem someone mentioned in another thread that some kind of malware can be sent without my knowledge.
What OS/SP ?
What exact version of avast ?
What version of Thunderbird ?
timeout means the application didn’t got a response from the server in time.
In many applications you can set the time the application is allowed to wait before it gives a timeout message.
