How to send and receive e-mails from multiple addresses through GMail?
One of the most annoying to have multiple Gmail accounts until recently was Gmail Notifier (the instrument for regular monitoring of the arrival of new mail) to allow for checking a single account at a time and to check more than one had to connect and disconnect continuously.
Well, now not only can you manage all your accounts together, or receive them all in one account "root" (if they have access POP, like most), but also send mail to appear sent from any of your addresses.
To receive e-mail from other accounts you own the account you want to open as a major, go to "Settings" and click on "Account". Under "Get mail from other accounts" click on "Add another email address of your property." Enter the address in the window that opens, continue to enter the user name and password of the address.
I recommend you highlight the "Apply to incoming messages labeled" so as not to confuse the various accounts when they are together. If you use Gmail, you can just leave everything else (just make sure that POP is enabled in "Forwarding and POP/IMAP and the POP server is pop.gmail.com), but if you have any other provider select" Other "in drop down menu "POP Server" and enter there the POP server of your provider of e-mail.
If you want to send on behalf of other accounts in the same window under "Send mail as" click on "Add another email address of your property, enter the name you want for the sender address from which you want to send, and then "Send Verification". This step serves to verify that you have access to GMail account entered. You must enter into that account and click the confirmation link. Now in your main you can change the composition of the message to the sender by clicking on the "From" field.
Explaining step by step is a bit 'hard-working but you will see that it is very easy to set it all and it is a big advantage for someone like me, has more than one active account on GMail.
There is one last small problem: When you download old messages from other accounts, these messages will be marked as unread. To mark all read at once, you must use a little trick:
1. In the "Settings", "Filters" create a new filter.
2. In "Has the words" please write: unread
3. Click OK if required and mark the boxes "Mark as Read" and "Also apply filter to conversations below.
4. Create the filter and wait if all the emails are marked as read.
5. Once done you can remove the filter to prevent marks messages as read on arrival and that you have not read yet.
