I've a dozen sites and I want all of their emails come to my one gmail id and I want to reply centrally from Gmail only. I've also added all of those emails in "send email as:" list in Gmail.
I could add email forwarders in my Cpanel but in that case I'll not be able to send email whose inboxes haven't been created( for example firstname.lastname@example.org). If I create email account then I'd receive emails in my inbox as well as forwared by the forwarder( to my gmail id).
Otherwise I can setup Gmail for my domain. But for a dozen emails I'm not sure if that'd be fine. I see in http://www.google.com/enterprise/apps/business/pricing.html that for up to 10 emails it is free. But then to send email from webhosting the php code will need SMTP login details and leaving my important gmail account details in my webhosting account is very risky given my sites have been compromised twice.
What is the best way to centralize all my emails so that I can read/reply/search from single place?
