Thunderbird emails with attachments not sending

A few days ago emails with attachments (pdf, jpeg), and of various sizes, stopped sending (timed out). The problem appears to only exist when I send from my desktop, not using webmail. All had been working fine prior to a few days ago. Emails without attachments send fine. Incoming emails (with and without attachments are also fine). I have had several discussions with my internet service provider who claim there is no issue at their end. I have checked my account/server settings in Thunderbird and all seems correct there. I'm using the POP mail server, if that is relevant. Any thoughts or suggestions welcome. Not being able to send emails with attachments if a major impediment.

Try without having your antivirus scanning outgoing mail. Or even with it turned off as outgoing email go into the system temp folder while sending and antivirus is more than capable of hanging the send process long enough for it to time out.

Thanks Matt. I went to try your suggestion but, after 3 days of problems, my emails with attachments seem to now be sending correctly (or at least the couple of tests I just did did so), so no point or capacity to test your idea. But I will remember it if the fix turns out not to be sustained. Cheers.
