Hotmail Drops Email Sent by Thunderbird
I have been struggling with this problem for a number of months. Here are the symptoms:
- Email sent to Hotmail via my SMTP server and Thunderbird never arrives, but I get no bounce message.
- Strangely, email sent to Hotmail via my SMTP server and the “mail” command arrives perfectly.
- Email sent as a reply to a Hotmail message using Thunderbird arrives perfectly.
I’m stuck scratching my head since it’s obviously not a server problem. I just can’t imagine what header Thunderbird is adding that Hotmail doesn’t like. I started this thread (continued here) on the Provo Linux Users Group hoping to get some answers. No luck yet.
