The native app seemed a little buggy with my att.net accounts so I installed K9 after reading through the forums. I was unable to send email through the native app, and it seems I can't send email with K9 either. This is with att.net as well as another server which synced well (folders and all) on the native app.

Any ideas?

I just see here that I received a "530 authentication required" message in K9 for the att account and "421 Maybe later is better. Pardon moi (#4.3.1)" in the other.

{{EDIT}} Problem solved!

 

AT&T Yahoo (U-verse) is my internet, landline, and cable service.

 

Yeah, I had to play around with it in order to get it setup. All the mail comes in okay (aside from self-created folders on att). I really don't want to call tech support. LOL It's sure to be a 2 hour long adventure.

 

They were already set on 25. Which seems to have something to do with the security setting. I changed it to SSL, which is what it should have been for att, according to what I've read on their site, and it doesn't seem to make a difference.

 

Thanks for taking the time to reply, Barbara. I figured out the problem. I had apparently unchecked the "require sign in" box. Once I checked it again, and added my info again, my outbox mail was sent. Unfortunately, I noticed that K9 won't bring my folders over either. =-/

Thanks again!
