- I have a multisite Wordpress website that will be sending out lots of registration emails - all identical, except for the name, username and password.
- The site domain ([url removed, login to view]) will be used for the from address (eg. webmaster at example1 dot com)
- The site is hosted on my VPS (CENTOS 6.2 with cPanel), there is no dedicated IP for the site itself (rDNS for the IP resolves to [url removed, login to view] on a Rackspace cloud server)
- Domain is registered with EuroDNS, all records can be changed as needed.
- When I started sending mails with the regular mail() function, most registration mails got blocked by spam-filters.
- A colleague suggested sending mails using Google smtp - this worked fine, until after about 50 mails all registration mails got blocked by Google itself.
- My experience in these matters is very limited :-)
<b>What I'm looking for:</b>
- Someone with more experience in the field of optimizing DNS setttings and stuff for sending out registration emails (rDNS, SPF, DKIM, HELO, ...) who can offer a solid, future-proof solution for the problem.
- Someone who is available to do the job within a couple of days.
- Non-Google solutions are welcome, though it would be nice if my client could easily check all email traffic (sent + received) without having to check the server logs.
Thanks for your response, and a short explanation of the solution you would suggest.
