Thread: Thunderbird duplicating sending of messages

  1. #1

    Default Thunderbird duplicating sending of messages

    For some reason when I send a message with attachments Thunderbird sends it twice. This has only started happening since I installed 12.3. I have been unable to find why it is doing this so unable to stop it. As far as I can tell this only happens to messages with attachments.
    Has anyone any ideas why this is happening and how to stop it.
    Any help gratefully received.

    I don't remember seeing anything like that, unless doing something
    intentionally.

    What kind of setup do you have, do you send directly from Thunderbird to
    your ISP (what ISP), or do you use a local mail server of some kind?
    Filtering, proxy?

    Does it happen when you send to any address, or to someone in
    particular? To a mail list, perhaps?

    Do you really mean that 2 emails are actually sent, or that you see 2 copies in the Sent folder? If the latter, and you are using IMAP, it may be that the IMAP server is placing a one copy in the sent folder, and Thunderbird is currently configured to do the same. Check your Account Settings > Copies and Folders to see if this is the case.

    To cover both replies.
    My ISP is BTInternet.com and my emails are sent directly from Thunderbird. As far as I have been able to establish it only happens to emails with attachments and it happens with any address.
    Two copies are actually sent, as I have received information to that effect, and two copies are placed in my sent folder.
    As for account settings they have never been changed, surely if it was an account setting it would happen with all emails not just those with attachments!

    I forgot to say that when I send an email with an attachment a box appears offering to compress the attachment irrespective of its size, this offers three types of compression or no compression at all.
    This is something I never had before the problem arose.

    I'm using Thunderbird (+DavMail) to connect to an Exchange server for my work email. I haven't experienced this behaviour. Is the compression option due to a TB add-on? (Auto Compress File add-on)

    Thunderbird alone does not offer compression, so you must be using some
    add on or something to do that compression. Remove it for the moment.

    Compare both send copies, using "ctrl-u" to display message source, to
    see if the messages are completely identical. If not, what is the
    difference might offer a clue.

    Carlos,

    You are quite right there was a compression tool in the add ons - I don.t know how it got there because I don't think I installed it. I have disabled it for now and will see what happens next time I send an attachment.

    Thank you.

    Problem now solved. Disabling the compression tool has cured the problem.

    Thanks for all help.

    Great. Thought that might be it.
