hello guys, yesterday i was searching in google , i saw your group
?guys, i m college student , and i? made postfix mail server with
squirrelmail client
internally in my college ( that was my project )
Great but I think you are missing one piece of the puzzle. You have
not mentioned any POP3/IMAP server above; without the POP3/IMAP server
how did you get Squirrelmail to work?
?but now my college want me to make it live
Hosting an email server is *not* trivial. I am not referring to the
setup but to the ongoing admin support you will have to provide.
Request your college to buy you bottles of antacid and pain relief
medicines. A small oops somewhere on your part will land in the
DNSBL (aka RBL) lists <
http://en.wikipedia.org/wiki/DNSBL>.
Some of us have gone through this exercise at some point in our career
and have concluded that it is best to out source this function.
May I ask what is the objective of this?
?guys , i need your guideline for that
?what should i do for that , do i need to buy domain and live ip or both ??
Domain - yes.
Static IP - yes.
DNS hosting - yes (read up on BIND and how to setup DNS records SOA,
NS, MX, A). Alternately, you can avail of free DNS hosting. Search
this list archive - it has been discussed at least a couple of times
in the past IIRC.
CentOS is a good platform for an email server.
Read up on:
SASL Auth
openSSL for certificates (to allow encrypted connections)
open email relays
How to remove your IP from DNSBL (RBL).
Grey/White listing.
Besides the above, some sites require that both forward and reverse IP
match to the same FQDN otherwise they do not accept messages from your
site. You will have to work with your ISP to create PTR record for
the range of IPs you buy.
Sounds like fun?
Post your experience if you decide to go ahead with it.
Otherwise buy a web hosting plan that allows unlimited (or close to
it) email addresses.
Best,
