We need to assign each subscriber to our site a unique email address that will barely be used. What is the best way to do this? We could host it but may be better to be hosted elsewhere.

This question came from our site for professional and enthusiast programmers.

What is the purpose of it if it will barely be used? Why would you not want to self host it? – Earlz May 27 '10 at 19:13
Google Apps if you don't want to host it yourself (1000s of barely used emails will hardly make a dent in a server) – Xorlev May 27 '10 at 19:14
I'm assuming you've got a list of these subscribers, probably in a database. In which case you'll be best off hosting it yourself and using a mail server which will let you store your users in a database. Postfix/Dovecot with a MySQL or LDAP database on Linux would be good, but you'd need to give more details for a detailed answer. – kaerast Jun 2 '10 at 14:38
It is not clear what you are looking for. If I were a subscriber with an e-mail account on your server that I rarely used, it would quickly become never used. If you want to contact me, ask me to provide an email address, then send to that. There are a number of methods of tracing bounce messages that do not require a new email address for each user. – BillThor Jun 2 '10 at 19:50

The people suggesting Gmail or Google Apps aren't understanding your question/needs.

You need to explain how, specifically, the email addresses will be used even if it's not often. Are they only used by a self-managed internal service or are they somehow accessible to the users whose subscriptions are tied to the internal addresses?

We have a similar setup. We have nearly 30.000 accounts with a 20-30 % utilization rate. We use MDaemon. The main problem with this setup is the regular customer mailbox maintenance and customer-wide mailing operations which do a real hardware burden (mostly disk I/O). I think that we need some good customer analytics to find out who really and how uses their e-mail accounts.

1and1 has really good deals on hosting packages and email if you buy a domain.

If you do not want to host it then Google Apps provides email for your own domain and such.
