No Sender No subject

I get this too. Started within the last month or so. I sometimes get 10 or 15 such messages. Solution is turn iPhone off, then back on (cycle it). Then those vacuous messages disappear.

I never see them on my mac/Mail.
 
Not just Gmail

I would like to add one thing to this discussion. I see a lot of mention of Gmail here, but I don't think this is a Gmail issue. I am having the same thing happen with an a POP account, a non Gmail account.

I hope they come up with a solution soon.
 
Not getting rid of them

I'm having this issue as well and have been for the past two weeks. The problem is it is now costing me money. I have tried completely reformatting my iPhone. I have tried all the suggestions below; I even deleted my gmail account off my iPhone and I still receive 50 copies of this email every 60 seconds. It has caused my data usage on the phone to skyrocket and I've had to upgrade to another plan to handle all the spam. It is costing me $30 more a month to deal with this issue. I would prefer to spend that money elsewhere. Really pissing me off.

There is no place in the options area for me to add information about blocking sender as was suggested below in notes and the mail.

HELP.

I unfortunately can give you no answer. I literally spent hours and hours trying to figure it out myself. What I ended up doing finally was setting it up via IMAP and just checking mail every 10-15 minutes or something.

Then like 1-2 months later I tried this method again and it working fine. Occasionally I still see it though but a simple restart fixes that problem.
 
My solution

Well, I can say that I got this "(No sender) - (No subject)"-problem after renaming (the description of) my email accounts on my iPhone 4 to "username@mydomain.com" (Setting > Email etc.). I just wanted the account names to be formatted in the same way.

Then I actually replicated the issue on my iPad by a mistake.

For me the solution was to rename the accounts back to something without the @-sign. Not necessarily the original name (description) of the email account. This worked on both of my devices.

It has nothing to do with SPAM in my case, just an IOS bug of some kind.

Ok, so I had this problem. If I back out of my inbox, (click the mailboxes button at the top), then i click on sent messages or some other folder, when I go back into my inbox the "No sender" message disappears. Still annoying though.
 
It worked for me...

Before you go resetting, try turning off/on the mail account.

Click "Settings" (the gears)
Scroll down to Mail, Contacts, Calendars
Select the infested account
Turn it off
Click done.
After that, re-enter the account and turn it back on.

I'll bet the infestation is gone and you didn't need more than 15-seconds to do it.;)
 
Turn off threading

Turning off "threading", immediately solved the issue for me.
 
Temp fix

I've been having this same problem for several months. I can't really say when it started or what caused it, but here's a temp workaround that works for me.

I view all of my email accounts in one folder (folder called "All Inboxes"). When I get the 'No sender, No subject" emails, all I do is hit the "Mailboxes" button at the top/left of the inbox screen. That takes me back to the Inbox root for all email account inboxes. Then I choose "All Inboxes" again and when I go back all the emails that had "No sender, No Subject" now appear normally with Sender, subject, message, etc...

It's just a temp fix, though, as usually later on I get more emails with missing info. Not a cure, but a quick temp fix. Hope it helps someone.
