User-Agent: Opera/9.80 (Windows NT 5.1; U; en) Presto/2.8.131 Version/11.10 Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2.17) Gecko/20110414 Thunderbird/3.1.10 I am unable to send mails with Thunderbird to a SMTP server that has a hostname containing a AAAA record and that requires TLS. If I disable TLS and send the mail unencrypted it works fine. If I enter the mail server's domain in the network.dns.ipv4OnlyDomains field it also works fine. Reproducible: Always Steps to Reproduce: 1. Get a host with working IPv6 connectivity. 2. Configure a new SMTP server. Make sure the entered host name has a AAAA record and the server will supports TLS. (For example mail.semidefinite.de, you don't actually need permission to send mails, as the connections is closed before you're asked for a username/password) 3. Connection security: STARTTLS (important), Authentication method: None (doesn't really matter). 4. Try to send a mail. Make sure it actually happens over IPv6 and uses encryption. Actual Results: The mail does not get sent: Send message error Sending of message failed. The message could not be sent using SMTP server mail.semidefinite.de for an unknown reason. Please verify that your SMTP server settings are correct and try again, or contact your network administrator.

Expected Results: Thunderbird starts the TLS handshake. I have confirmed this bug at home with the current Windows XP 32 bit version as well as at work with the Linux 64 bit version. I'm pretty sure it's a general problem not related to the OS.

David shall I move that to Core ? And if I do NSS or NSPR ?

I can confirm: * My earlier comment of this happening on Linux 64 bit was wrong. I tested this about a month ago and got the same generic error message, but couldn't tcpdump the connection at that time, so I assumed it was the same problem. It wasn't, it was completely unrelated. Sorry about that. * Everything works fine with Windows 7 64 bit. * My SO_RCVBUF defaults to >64 KB. So yeah, probably the same problem, just for Thunderbird instead of Firefox. I'm not familiar with the Mozilla build system, will the patch posted in that other bug fix it for Thunderbird too, or was it fixed in a Firefox-only place? Is a beta build of Thunderbird that includes this patch available to test the fix?
OS: All → Windows XP
Hardware: All → x86
The fix is in core code, so Thunderbird should get it. There are no builds with that patch in it, because it hasn't been checked in.
