Hi Dan, well, just tell me wich zon you need the
extra info.
About using webmail at 80 port, we had it that way
and same thing, had to pass it to 8383 again this week, so we can redirect all
th MAIL aliases from our customers to other WEB:80 that currently redirects to
our IMAIL:8383 server so we can "force" the users to get catched up with the
geo.net.co:8383 webmail, wich doesnt hangs the CPU.
About the host headers, i think thats an extra from
Imail, you just put at the vhost configuration screen, at the HOST ALIASES,
imail.domain.com and you put a CNAME (OR A-RECORD) pointing to your servers IP
address. At that stage, everytime a user goes to http://imail.domain.com :8383
(or any of your imail webmail setting port), imail will catch the headers (And
add them to the logging proceess), wich simplifies the loggin stage (Try it, its
cool if your system doesnt behave like mine! now i have to make all of them type
their domain).
Basically I use CNAMES because if we have some
migration, we only need to change 1 record, basically thats the
reason.
I dont get this (sorry!)
No SPF text seen. (A simple TXT
record of "v=spf1 +mx -all" will do.

problem with WebMail + DNS + W2k
Several things come to mind.
a)
No Firewall? Sounds risky.
b)
You don't show any examples of the other DNS entries. You stopped just when it
was about to get interesting.
c)
If there's not a webserver on this do-everything box, you can put IMail on
port 80 and simplify everybodies life.
d)
Your zone serial number should be in the form yyyymmddxx, looks like the 4 got
dropped.
e)
CNAMES cost extra references. Unless there is a good administrative reason for
using them (like you don't control both the name and alias), you should just
use A records.
f)
No SPF text seen. (A simple TXT record of "v=spf1 +mx -all" will
do.
h)
How do you get IMail to notice the Host headers? I'd like to do that. I make
my users type the whole thing! I thought you had to use separat IPs but that
would be A records, no CNAMEs.

Hi there:
Well, after a full week reinstalling and
reinstalling and looking up for some help, we found the following
strange thing with our system.
We do a clean installation of webmail on our
server (IBM Xserier 235, 2 Xeon x 3.2 Ghz, 2GB RAM), with Windows 2000
Server, MS DNS Server, Fprot, Declude AV, Declude Hijack.
The server is the Primary DNS Server of our
Network.
The Imail server, responds to hostname
(geo.net.co)
(geo.net.co) is configured as a Primary zone in
our DNS. (Remember that the DNS server runs on the SAME Imail
Server).
geo.net.co has the following created records
(I think this is not ok, so if you see some missleading, thanks!,
)
;
; Database file geo.net.co.dns for
geo.net.co zone.
; Zone version:
2001042332
;
@
IN SOA ns1.geo.net.co. hostmaster.geo.net.co.
(
2001042332 ; serial
number
3600 ;
refresh
3600 ;
retry
86400 ;
expire
86400 ) ; minimum TTL
; Zone NS records
@
NS dns1.geo.net.co.
@
NS ns1.geo.net.co.
@
NS ns2.geo.net.co.
@
NS imail.noc-geonet.com.
@
NS dns2.geo.net.co.
; Zone records
@
A 200.124.168.11
@
MX 10 ns1.geo.net.co.
dns1
A 200.124.168.11
dns2
A 200.124.168.11
ns1
A 200.124.168.11
ns2
A 200.124.168.12
smtp
CNAME dns1.geonetsa.com.
pop3
CNAME dns1.geonetsa.com.
So, at this server, i have like 200 Virtual
domains, i make an CNAME record at each one, pointing at geo.net.co so when
they log in to the webmail, they dont have to use @domain.com appended to
the username.
The strange thing
is:
When i use http://200.124.168.11:8383 for logging
in to my Webmail, using the perfmon i see that iwebmsg only uses like 10% of
the cpu for the complete logon process, but if i use for example http://mail.domain.com:8383, the cpu
goes nuts, like 90-100% of ussage for like 3 seconds that is the time of the
complete logon process.
So, the only way that the cpu, doesnt hang is
if I use: http://200.124.168.11:8383 or
Any ideas???
