User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:29.0) Gecko/20100101 Firefox/29.0 Iceweasel/29.0 (Beta/Release) Build ID: 20140429174502 Steps to reproduce: compose a new mail or reply to a received mail. Type in the content and click on send icon. Actual results: It just showed "Sending email failed" Expected results: at the least it should tell why it failed, whether it was unable to connect to server, whether it failed to authenticate or some other error. and ideally an email application should be able to send emails. Phone: ZTE Open, Firefox Os 1.2 (ZTE provided version). It used to work with 1.3.0 pre release. I have 3 email accounts and one of them is set as default (when it is not selected as default aslo it fails).

attaching logcat

git commit info 9969e2c8b0f3 build identifier 20131114004004 mail servers mail.dreamhost.com, smtp.autistici.org (default) it is using IMAP+SMTP detailed logcat shows it is unable to connect

adb logcat -v time -s GeckoDump:V Gecko:V GeckoConsole:V OomLogger:V | tee firefox-full.log

having enable gaia debug traces or look at adb logcat to find out server is not responding is not quite right. I was able to send email using another account so sending emails still work, problem is useful error message.

I agree the error messages for failure to send an email message are very bad. Bug 921050 is implementing sending emails in the background and will be landing in the next few weeks. This will address timeout related issues, but it will also greatly improve our error situation. I'm duping to it since I believe this covers the various problems you cited here. Thank you very much for sticking with the Gaia email app and providing a logcat!
