When using Thunderbird (all versions since 2.x), I am unable to get a filter to forward an email.
I want to forward a copy of certain incoming emails to my wife’s account. The filter will work to move the message to another folder, or any other rule. However, the rule to forward the email always gets the error message from Thunderbird, “Sending of message failed.” with no other help. So, it appears to execute the rule, but the actual sending of the forward does not work. In addition, the message just disappears, it is not in the Outbox.
Google search shows tips that the rule must be on a mail account, and not on local folders. I have done that.
This is one supreme aggravation and has been around for a long time on many versions. I can’t believe there is no workaround or fix.
Hopefully, the Lounge will come up with the answer! Thanks!
