I have a client with 500+ employees– we have been providing email services for them, but we have permanent white-listing problems on our server. They probably need at least 500 to 1000 email in-boxes with SMTP capability and maybe at least 100 megs of storage. They need a professional business solution (free google apps or plain old gmail are not options).
They have been getting mail through us for years, but its not working well. Our mail flows through an Exim server (WHM), and there’s no whitelisting, and I don’t think we even use SPF or DKIM. We can set all that up, but I’m not sure it will help. They might just need a 3rd party email service provider….
I’m thinking of recommending google apps, but I think it’s far more than they are willing to spend ($2500 per month unless they offer a volume discount). Fusemail and Fastmail seem to have potential, but I don’t know anything about them (it looks like either would cost a few hundred per month or a few thousand per year).
Can anyone recommend a solution here? Setting up a Zimbra or Postfix server are probably not options because we don’t have a sysadmin, and I’m too busy writing software for clients to spend time on something like that… I’m basically looking for a cheap, but reliable email service provider…
