Help! Another email server question.
 

I'm new to Linux. I need to set up an email server just to handle POP and SMTP for 10 different domains. I am sure Sendmail or Qmail can handle this but I need some help finding a quick and dirty setup for this.

www.sendmail.org sendmail (smtp server)
www.eudora.com qpopper (pop3 server)
you have a readme in each which is very straight forward

I love Sendmail, really, I do,, but you must be the only person I've ever seen to call it straightforward :)

I was reading the Sendmail FAQ and noticed why you posted the Eudora link, Sendmail only supports SMTP. :)

Thanks.

I also noticed that Qpopper by Eudora doesn't support virtual domains. There is a work around for it but I don't know if my client will want to work with it that way.

Is there any package that supports SMTP, POP, and virtual domains? It can be a commercial package if need be.

Some larger ISP's use seperate username / e-mail addresses. All usernames are a serialized number/letter combo. E-mail addresses are all managed by virutal user tables. So sendmain knows that somebody@thisdomain.com is user A234BC. The username/password (Call it Customer ID instead of Username) is only used to configure the mail client for retrieval

cottonmouth:
why do you need virtaul domains in qpoper
mail works like this
you have a user joe
and your machine is setup to have lets say dns records for
mail.yourlastname.com mail.yourfirm.com mail.yourhobbie.org

if you setup sendmail by those 10 short points in sendmail's README
you will receive mail for
joe@yourlastname.com , joe@yourfirm.com joe@yourhobbie.org

if you have another joe you wants to recevie seperate email for domain yourfirm.com, then you need to make new user say joe1 edit /etc/mail/virtusertable (prior you have to enable support for it when building sendmail.cf) and put line like
joe@yourfirm.com joe1
+restart sendmail

to check your mail through qpop it doesn't matter what domain you are using. You can tell your clients different domain names for each domain to be cooler isp, but no difference.

the only catch is if you set up pop3s (secure pop3 - port 995) there you can use only one host since you can only use one certificate. and for other you will get error message that the certificate doesn't belong to this host.

btw
sendmail is indeed very straightforward ( if you have straightforward setup - if not it can get tricky)
qpopper is little more fun to tackle, but no big deal once you read the Install notes (which are there to be read :))
good luck

if any more troubles? just ask don't be shy ;)

Ok, I understand now. However, Sendmail doesn't support POP, at least from what I have read. I think we are leaning towards Open Mail 7.0 because it supports Outlook users which is what most of their clients will be using.

Anyone have any experience with this product?
