Setting up webmail for multiple domains (not as addons or parked)

Hello,

I am currently hosting some websites with individual cPanel accounts and I'm using Roundcube with specific plug-ins as my mail client.

I would like to install Roundcube just once on one domain and have all clients visit this domain for their emails, rather than installing Roundcube for each account. It also solves the problem of having to automate the Roundcube installation which is proving extremely difficult.

So, I've been searching the internet for days and playing around with WHM/cPanel and cannot seem to get what I want.

Just to clarify - www.first-domain.com, www.second-domain.com and www.third-domain.com will all visit www.email-service.com to pick up their emails. None of the domains are hosted as add-on domains or are parked so I cannot create an account in www.email-service.com which would be an email address from their domain.

I've tried playing with MX settings setting them all pointing to www.email-service.com but this has proved useless.

I am gradually automating every single stage of the account set-up process so would like a solution to conform to this.

Any ideas?

 

Yes, I am. But looking to have all separate accounts i set up in WHM to channel emails through this as mail server. I don't have full root access with my provider but I'm starting to realise I may have to switch to somewhere that does so i can do this - am i right?

Thanks

 

I don't necessarily need to have the snappy domain name, but i do need to be able to host the email service on a separate account. Each account only uses about 15mb but I have to allocate a lot more due to email. If could get all email amounts from one cpanel account i could just allocate 20mb to each account and then adjust the email account limit to cope, saving me a lot of wasted space. Is this possible without needing a mail server (and as such requiring full root access)?

Thanks for your help

 

Just to clarify, when I say restrict space I mean to restrict web space. As each website is only c15mb I am currently providing 250mb for each account to allow enough email storage and some users are nearing this limit while others are at about 20mb for website and email combined. I figured that putting email on a separate account would mean I can increase this as necessary while keeping the cpanel account limits for websites at 20mb. doing this will allow me to have better planning for the number of accounts that can be put on my whm. I am currently upgrading my plan frequently just to get more space when technically I dont need it. Out of interest, what security concerns are introduced when using a mail server instead of using the default mail on the account?

Thanks again.

 

Thank you,

The web space i need to allocate is not going to need much space - its a custom CMS system that creates a basic listing almost. Which is why i have an interest in getting all mail from all accounts on to one secluded account i can adjust as necessary. As I'm paying per gb usage at the moment i am upgrading per 4 accounts as i allocate 250mb - if 10 people only use 20mb then that's 2.8gb I'm paying for but not using. If i could get all mail out of their individual accounts onto a separate space i can upgrade only when i actually need to. Clients could also get all the email space they need in this set up.

Do you understand my logic for this? I may be totally missing something here - but if there is a solution without much work then great. I'm just trying to explore options here - I'm not necessarily focussed on one solution.

I get the security comments. I appreciate I would have to find such a solution.

My initial idea was to combat this issue by having a mail server and using roundcube as the client for simplicity and provide some revenue in the form of advertising within this. But I appreciate this may not be the solution I am looking for.

Thanks

 

I think youre right. I just wanted to avoid a migration of accounts, but I guess sooner is better than later.

Thanks for your help on this topic, if nothing else it has helped me learn a few things!
