if user press home button while image sending is in progress.apple provides 10 minutes to complete your small tasks. which of them will perform better ?

It's better to send it by web service. As apple's privacy policy says you can't send Email or SMS without user's Interaction. If you send the image using Email there are chances of your app getting rejected.
Regarding the performance web service will work fine.

is there any chance of app rejection if i use webservice or Smtp Email ?
NO application will not rejected.BUt User confirmation needed.

Is possible send emails from a non Gmail SMTP email account in firebase cloud functions?
I couldn't find this info.
You need to enable billing on your Firebase project. As per the documentation, "this is required to send requests to non-Google services". More details here --> https://github.com/firebase/functions-samples/tree/master/quickstarts/email-users#functions-code

We are developing a web app Application and planning to use Push Notification to send "One Time Password". But as per Apple Guidelines, "Apps that send sensitive personal or confidential information using Push Notifications will be rejected". Please suggest.
The answer is in the body of the question, isn't it?
I think sending a password in plain text via push notification is problematic. Any tool could catch it in mid-transfer.
Perhaps you should at the least send it encrypted and de-crypt it on the client-side.

Is it possible to develop an app to handle an incoming phone call for iPhone? I mean, I'm thinking to develop an app to record phone conversation for both outgoing and incoming calls.
If it is an outgoing call, can user make a standard phone call and the voice conversation be recorded?
If it is an incoming call, can app be opened/activated when there is an incoming call and the user talk while the conversation is recorded?
(There is a Core Telephone Framework:
but I don't know if it would help.)
Can anyone advise?
Ignoring legal implications, it is not possible over their provider's network.
(ex: Verizon)

Mailchimp, the online service for sending newsletters, has an statistics about how many people marked email you sent as spam. Does anybody know how this works? I am asking because I was thinking about how to implement this into my CMS which sends newsletters as well. Thanks for replies!
It's called FBL (feedback loop) and means that you register your MTAs (email sending servers) at the ISPs that supports FBLs (Yahoo, Hotmail etc.)
All you have to do is to sign up for every available FBL via their forms and then they will send you an email every time someone mark email sent from those servers as spam (spam complaints).
Then you'll have to parse those emails to get the information from it.
Have you checked Mailchimp Support?

An abnormally high bounce rate is another indicator. Look through your hard bounces, and read the SMTP replies. Spam filters sometimes leave little clues about why they blocked your campaign (See: http://kb.mailchimp.com/article/why-did-my-email-bounce-smtp-replies).

I have an iphone application in that I have to log in to gmail through my program and then from that account I have to send an email to application users automatiocally. I dont want to show the sending mail window to user. Please give some solution..........
It can be done through webservices but it may not be a good idea to implement it.
I think your idea wont be very successful with iPhone environment as Apple wont approve your idea.
I think you will understand this better if you go through Apple's Developer App Guidelines for iOS.
That is because while sending mail or to login into gmail you would require user's permission and you cannot send email to user without his permission.
Hope this helps you
