How to setup GMail SMTP on iOS

This tutorial explains how you can setup your iOS device (iPad/iPhone) to use multiple SMTP servers from GMail. This is especially useful if you have trouble sending emails while connected to the VPN. 1. Tap the settings icon You will then get into the iOS settings menu, like you can see on this screenshot ->
2. Get to the email related settings Tap "Mail, Contacts, Calendars", then choose the Account for the e-mail (in this case Gmail)
3. Tap the Account field
4. Tap the SMTP field
5. Tap the smtp.gmail.com button under the Primary Server
6. You should turn off all previous server settings Do so by clicking on the "ON" button. The menu will then look like on the next screenshot.
See? You successfully turned off all previous settings. Good! Let's go on by clicking on the blue "Done" button.
7. Now tap "Add Server" button (please keep in mind that all the others servers should be set to OFF)
8. Fill the "Host Name" field with these SMTP server IPs from GMail: 74.125.136.108, 74.125.133.108, 74.125.142.108, 173.194.66.108, 173.194.67.108, 173.194.70.108, 173.194.66.109, 173.194.70.16, 173.194.66.16, After you finish this tap "Save". Should you see a message regarding "imap.gmail.com is missing", you can disregard this. It's related to incoming email settings which do not matter here.
9. Now go back to the Account window. Make sure your GMail account data is correctly entered here: Name: enter the name you want to be appear as sender Address: enter your Gmail address (e.g. myacc@gmail.com) Password: enter your Gmail password Description: doesn't matter, e.g. "Gmail" Now please choose the "Advanced" button
10. Here you can change option for using SSL and Server Port as recommended Possible settings are: Use SSL: On Server Port: 25 or 465 or 587 That's all. Save+close all windows and try to send emails while connected to the VPN. Should you still experience problems sending emails, please try all 3 ports.
