I'm posting this here because I have no where else to turn, maybe someone can help me. Or, I can just publicly shame Yahoo and Google.

The Motorola Android (Verizon) does not connect with Yahoo! Mail properly.  There are two big glitches:

1. Deleted messages reappear the next day, and read messages re-highlight as unread.  There's no predictability or periodicity to this.  It can happen in an hour, or in two days.

2. When you reply to an email on the Android, it saves thousands of copies in your Yahoo! sent mail box.  Last night I deleted 46000 messages.

This is what I've done so far.  I've followed the Verizon and internet directions:

1. Make sure Wi-Fi is turned off
2. Press the E-Mail icon (the default Android E-Mail application)
3. Enter your Yahoo E-Mail address and password
4. Press "Manual Setup" in the lower left hand corner
5. For "Incoming Server Settings" set the IMAP server to "imap.mail.yahoo.com" and the Port to 143
6. For "Outgoing Server Settings" set the SMTP Server to "smtp.mobile.mail.yahoo.com" and the Port to 587
7. Check "Require sign-in" and press Next
8. Select how often your Droid will check for Email, and choose default options
9. Give the account a name and set your display name for outgoing messages

With these instructions the phone deals with email properly except for the two glitches noted above.

I have tried variations:

1. Removed the "mobile" in step 6 (so it is just smtp.mail.yahoo.com).  No.
2. I have turned off the "saved sent messages" in the Yahoo! Mail account options.  It still saves.
3. I have entered the username as both" XXX@yahoo".com and just XXX.  No.
4. I have tried this with the free Yahoo! Mail as well as with the paid Yahoo! Mail Plus.  No.
5. I have tried driving over it.  No.
6. I have tried changing the outgoing settings to plus.smtp.mail.yahoo.com as well as plus.smtp.mobile.mail.yahoo.com

I realize I can just switch to GMail, but if anyone knows how to resolve this, please let me know.

Update:

7. I tried changing the incoming mail server to imap.n.mail.yahoo.com.  No.


I determined that the copies are made each time the Android connects to Yahoo to check for emails, e.g. every 15 minutes, every time you send another email, or every time you hit refresh.  It makes 2-3 copies each time (can't figure out why) but over the course of a day...

Update 1/24/10


The problem appears to be hardware or carrier, not software.  The Motorola Droid runs 2.0 and has the problem, while mytouch runs 1.8 and is free of this abomination.

However, the  Nexus One on Tmobile has the problem, too. He said he fixed the problem by removing himself from his Contacts.  This did not work for me (I wasn't in the contacts.)  (Nope-- this turned out not to work.)
