For the past 18 months, I've been routing all outbound email from the shared hosting servers via Sendgrid, and their SMTP relay service. This has enabled the old IP's to remain clean, and prevent them from being black listed by the RBL lists.
I've just signed up for a new service, provided by Mailchannels. This is specifically aimed at ensuring the best delivery rate, along with the ability for me to identify abusers / spammers / compromised accounts etc, and maintain the integrity of the hosting platform.
I've initially switched CP1 over to this new service, and I've been monitoring and setting it up over the last 24 hours. So far, VERY impressed!
I've configured all the accounts with the correct SPF value where I have access to the DNS servers, so all the correct routing and authentication for the domains is in place.
This is an additional cost to myself, and it's not a cost I'm passing over to you, the customers. Hopefully, you will see a benefit from this, as email deliver-ability will be pretty consistent now.
The only issue I've found has been where in XF, you have a bounced email address configured, or the sending address ISN'T on the same domain (such as a hotmail or gmail account). The way the address is formatted causes the mail to be blocked by the receiving party (and would have been previously), but I wasn't aware of this until I had access to the additional reporting by this new service. I've fixed the XF installs that were set up like this.
I'm going to run with the single server on this for a month, and all being well, will migrate everything else over in the new year.
Any questions or issues, please let me know.
