I currently have a "Windows MultiSite" hosting account with Verio. I have one site up and running for 3 months. Recently I noticed that when my users fill out the forms and submit them, too often I get errors and the forms never get emailed back to my office. I should of noticed this sooner because I've always had problems connecting to my POP email accounts through Outlook. The outlook error has to do with not being able to connect to SMTP; this is the same error I get on the website when users attempt to send the form. Verio claims that the error is due to too many spam emails hitting their servers. Many forms error out, usually they timeout trying to connect, and the email never gets sent.
I have a 30 minute commitment to return a quote to those that submit the forms on my site. I need reliable email.
On a VPS will I have the same problems I'm having with my shared hosting account in regard to email, or is it independent of the other sites? Keep in mind that it's not my email accounts that are being overwhelmed with junk email.
Do the control panels offered create zone files and MX(sp) records? Will I need to learn a lot of networking?
I use very little bandwidth and disk space. Within 4 months I'll have to host about 10 sites. I'm looking for recommendations for a windows based VPS.
