Very Slow "Send" in TBird email

more options

Recently (past 2 weeks) it takes a very long time for an email message to "send". Once in a while it will be almost normal speed but it might take as long as 20 seconds or more to send. Incoming seems fine and everything else seems to be working. My gmail a/c is very fast as are all other sites when loading. Has something happened recently that would cause this? Thanks so much for your help. mac a.

Hello there macallen We have read your message. We try to help you.


Thunderbird does send slowly by most standards, leaving the sending dialog up until it gets a message from the server that it has the message and is sending it on. Most programs send in the background and Thunderbird can do that as well, but error reporting of transmission errors is wanting. You can enable sending in the background by setting mailnews.sendInBackground to true in the Config Editor and Thunderbird send will be much faster. But you might want to look at the dependent bugs on this bug . before you just "do it" to make sure you can live with the consequences. Most users will not have an issue.
