Email hosting solutions/email servers

If cost is a problem, @Matt probably has the best tip for @domain emails if you need to manage alot of web sites. That is fork out for a cpanel/WHM VPS license and only setup @domain emails for every Centmin Mod hosted domains and offload them to cpanel/WHM. That one cpanel/WHM VPS license instance could handle every Centmin Mod server you own hosted domains. That way you can create as many @domain email accounts for every domain you own via cpanel/WHM. If you have many domains and email user accounts, the cost of cpanel/WHM will pay for itself compared to paying for 3rd party @domain hosting with likes of Google Gsuite which charger per user at US$50/yr. Though with Google Gsuite if you don't really need 10 separate accounts with separate inboxes and can make do with 1 inbox/user with domain aliases it can get cheaper so only need 1 user account with alias usernames going to the same account. Which means US$50/yr cost per domain user x 1.

But if you go self-hosted route, remember that any and all security, uptime/downtime, ip reputation, email delivery, blacklist, spam and virus management is your responsibility to troubleshoot and fix. If they need to move web hosts and servers, you'd also be responsible for migrating all emails and email accounts intact to the new web hosts servers too and need to be moved in a way that maintains email service uptime and operation during the migration. If you have separate clients, then may need a cpanel/WHM VPS for each client unless you want to tell other clients you're moving email servers when one client needs to move.

Though cpanel/WHM has a robust and solid per account migration utility from one cpanel/WHM server to another so that makes it easier.

Also depending on uptime requirements, may need to setup a primary and secondary backup mail server so may need 2x cpanel/WHM VPS servers to operate in primary and secondary mail server capacities.

Ultimately depends on total operate costing for your clients if they choose a paid Google GSuite solution versus self-hosted. If the client can justify 10 users x US$50/yr = US$500/yr, then probably the best approach in my opinion as opposed to your doing it for the client where I hope you are charging at least that much for your time.

 

Learning is good just don't use paying clients as a guinea pig - could backfire big time if you screw up

 

coincidentally while browsing WHT forums came across a relevant thread of potential issues you need to deal with when self hosting your emails for clients = server IP blacklist removal and monitoring How do you do with outgoing emails from your clients | Web Hosting Talk

In which one client's spam causes server IP to be blacklisted, that means every client on the server will not be able to send emails effectively until the server IP is removed from the blacklist databases (maybe more than one blacklist database).

In which case you'd also have to fork out for IP blacklist monitoring services like with Hetrixtools (affiliate link) which has a free plan for 32 monitors but at 24hr frequency with 15 day report history.

 

Pretty sure for that WHT user it's clients sending outbound via smtp configured email clients/apps I suspect

 

Yeah at an additional cost of at least US$18-25/month for 40k emails per month.

 

Yeah if you're self hosting a mail server properly - for cpanel/WHM VPS license, mailchannels smtp relay, virus/malware scanning and blacklist monitoring requirements and additional disk, cpu and memory requirements etc, then the cost will be roughly between US$60-100/month if you include a remote backup option or double that if you need a secondary mail backup instance as well. For some folks it makes Google Gsuite at US$50/yr per user a relatively inexpensive option somewhat

 

Well family can always pay for their own email services LOL

Though in @JJC84's context, it's for paying clients so usually the client is paying for it
