Can't send Yahoo Mail

I'm noticing that I'm frequently having problems sending Yahoo Mail on my iPhone 3GS running 4.2.1. Most of the time it times out with a "Cannot Send Mail" error which states "The connection to the outgoing server "apple.smtp.mail.yahoo.com" failed. Additional Outgoing Mail Servers can be configured in Settings > Mai, Contacts, Calendars".

I am successfully able to connect to apple.smtp.mail.yahoo.com, if I type "telnet apple.smtp.mail.yahoo.com 587" or "telnet apple.smtp.mail.yahoo.com 25" on my PC's command prompt window, meaning the servers are up.

I can receive mail without issue and I can also save drafts, only sending is a problem.

I think I figured out why this is broken. I removed my Yahoo account from the phone, rebooted the phone and then added it back in. Sending now works, but I notice it's using port 465 now to send mail and 993 to receive mail. Those ports are the SSL smtp and imaps (SSL) ports respectively. It looks like the iPhone now actually sends and receives Yahoo mail securely under iOS 4.2.1! It's about time.

Well I've seen this problem again two additional times. The first time it seemed to fix itself after I sent an email using MobileMe. The second time I had to turn off Mail in the Yahoo Account on the phone and then kill the mail app and then turn mail back on.

There's definitely a problem that is occurring periodically since upgrading to iOS 4.2.1, though I don't know if the problem is with Yahoo's servers or the iOS itself. I do not that when the phone fails to connect to the servers, my PC has no problem connecting.

It only happened when I put the new app to FIND MY IPHONE onto the iPad and iPhone and haad to create the apple Mobile Me account. So, I am removing the application and deleting the account on my phone and iPad. I will also remove but then re-add the yahoo account. Hope it works, but it is suspect that this happened exactly with the add of Mobile Me and Find the phone.

I am having the same issue. I tried everything listed and the problem is still intermittent. I can send a few emails fine, then all of a sudden I get the error message. When I am in another app, I can hear emails getting sent that I tried to send an hour ago. It's quite vexing and did only start when I upgraded to 4.2.1

I have no problems receiving email in Yahoo, or sending mail from any other account on the phone.
