Maximum users for mail server

HI I just wanted to see how many users people had on their systems.. i am looking a the 2-quad core xserve, with 16gb ram 3 15,000 rpm disks in raid 5. I currently have 700 users but and i want this server to last until i at least double the users can anyone out there verify they have 1-2K users without a problem? Apple sales claims that it shouldn't be a problem. thanks! chrissy

Hi
You don't say what other services you will be hosting so its difficult to give any clear advice?
If you are looking at an Open Directory Master Role for your server with networked home folders then look to balance the load with another server every 60-180 users. This is a loose figure as a lot will depend on the quality and speed of the network as well as client usage. 300 Primary School children won't have as much impact probably as a Design Studio of 10-20 Designers using Photoshop and the rest as well as 3D rendering and some Video production.
I can't really comment on Mail Services at that figure. Seems to work fine with the amount of users of my experience which varies site to site, anything from 5 to 80 Users.
Hopefully there will be others who can offer more insight regarding other services such as Web etc.
If you were wondering about iCal, Wiki and Blog these are new features and I doubt if there is anyone yet with experience of that amount of users? Perhaps you'll be the first? Let us know how you get on.
Hope this helps, Tony

VersaMail - "Unable to resolve name" error for mail server

I've had an intermittent but frequent problem with VersaMail when I try to connect to get my email. I frequently get the following message:
"Unable to resolve name pop.mindspring.com. Check your DNS settings or enter the IP address for your mail server."
I also get it occasionally for my Yahoo.com mail addresses as well, so it's not unique to Mindspring.com. Sometimes it happens a lot, but sometimes I get right in with no problems, so the settings I have appear to work - when they want to. Needless to say, it's frustrating and annoying, so if anyone has a way to resolve this, I'd appreciate knowing it.
Thanks.

This question was solved.
View Solution.

Problem solved! I had Googled for answers and had found an explanation of DNS servers on another forum where someone was having a similar problem. It seems that DNS servers simply take the domain name we use and search for the IP address for that domain name, then hook us up to that IP address. The error message I was getting was that I needed to check my DNS settings or enter the IP address, so it seemed only logical to me that if I could bypass those goofy DNS servers with their "now I'll do it, now I won't" bad attitude, perhaps I could connect directly with the mail servers. Your tip on how to find the IP address of the mail servers by pinging them was the missing piece I needed. I deleted the POP and SMTP server names for each account I'd set up in VersaMail, replacing them with the appropriate IP addresses, and I can now connect reliably with any of the servers, first time, every time - and lightning fast.
Thanks for your help!

Dns setting require for mail server 2013

Hello Support,
I have install exchange server 2013 and working fine but right now i have some change in DNS server record and my mail services stop. what record add to start my mail services ( sent and received). till now exchange server mail box give the error mail not
connected with server. Please revered ASAP.

couple of things to notice. if you saying your exchange services stopped... this wont happen because of DNS or are you saying you exchange is not working/mail flow.
now i would suggest to quickly check the mail services. run a test for inbound and outbound at exrca.com there you will have the proper answer that what you have missed.
and at last.. for DNS.. you need MX and A record for your email server for basic functioning .. and for autodiscover couple of more. lets verify the MX and A record first and then verify the send and receive connector. to verify MX do a Nslookup as below
>cmd
>nsloookup   {This should resolve to your local DNS if you running this from exchange server, which is recommended and should not time out}
>set type=mx
> your-domain.com {This should result "A" record / FQDN of your mail server}
> set type=A {To verify the above FQDN should point to right IP}
> mail.your-domain.com [assuming that in MX output you got mail-your-domain.com]
> 1.1.1.1 [IP of your email server]
if you are able to verify above then your chances are you dont have issue with DNS.
Make sure from oursite you are able to telnet t tour exchange server on port 25 and from inside you are able to resolve names from your exchange server and also have internet access.if you able to verify till this point then its the turn now to verify send
and receive connector. one easy way is exrca.com and then share the results.
to verify if your exchange is configured properly please follow this link.

How should I partition 10 gig HD for Mail Server???

I plan on making a mail server but I am not sure what partitions to use. I have a 10 gig HD, and I dont want to partition it wrong then have no idea how to go back and redo the partitions without reinstalling. I was thinking something like:
/ = 2gig
swap = 512mb
/opt = 3gig
/export/home = 4 gig
Any idea what steps I should take first to creating a mail server? I still can't find the pop and imap server packages.

For POP3, I suggest qpopper from Eudora. www.eudora.com/qpopper.
It virtually installed itself and seems to work fine right from the start. Now if I could only figure out how to get Sendmail to work with SMTP. All my Internet mail gets refused by Sendmail, incoming and outgoing.

Host name for mail server

Hi,
i am developing an application in which i can read the inbox of my outlook.
my problem is that i am not able to connect mail server and getting 'messaging Exception' as
A remote host did not respond within the time out period .
I think i am not able to give the HOST name correctly .
How can i get the host name and from where?
Thanks,
Dinesh

You can get the hostname by clicking on the account properties in outlook, but the port you connect to must be opened by your system admin.

Can't find correct hostname for mail server

I'm having trouble finding what I'm supposed to put in the "hostname" field for in- and outgoing e-mail. The e-mail I'm trying to set up is of the format "[email protected]". I have tried with "mail.ardal.skulenett.no" and "mx5.agnitio.no", which was the result I got from running a nslookup on the address (see exact output below). I'm pretty much stumped now, and was hoping someone here could give me some pointers on what to try next.

You'll need to ask your email provider for their exact configuration. Server address, ports if different from default etc.
Each Email provider has their own configuration and only they now how it is set up.
Usually there is some kind of documentation outlining this.

im sure the commands/coding/scripting can be cleaned up, but this worked for me.
thanks Vibhor Amrodia for your time and help!
(note for others as reference)
the ports in red i changed accordingly ... eg 80,110,25, etc
the neon green 1 changed for every rule i added... eg: 1,2,3,4,5, etc
for others that need help with similar situation here is a great reference website that helped me alot with setting port forwarding , internet sharing , and NAT / PAT on the ASA 5512-x , im sure it works with the updated asa 5505 as well running 8.3+

Here's a simple fix for Mail constantly asking for account password

This one was driving me nuts, but now I have a fix...I think. Open up Keychain Access in Utiliites. Double click the entry in the login keychain, then check "Show Password." Give your login password and hit the "Allow" button. After the pword is shown, just close the box. That's it. No more need to redo all the pwords in Mail and Keychain. Works for me. Mail seems to need some hand holding from time to time.

My e-mail provider is Verizon. If I'm being asked for the password for the main account, I double-click on this in the login keychain shown below. But since I'm using Snow Leopard, this might appear differently for you, although I doubt it.

Send E-Mail over two different Mail Server ?

I successfully configured E-Mail in HTML DB according to the How-To "Send E-Mail from HTML DB Applications".
There's one point in our environment that is a little bit special. The HTML DB application should work for two companies. So it works for company A because every message is sent to the corresponding Mail Server. Of course messages to company B are rejected because the Mail Server of company A is not configured to accept these messages ( relaying denied... ). Is this a Mail Server administration issue or is there a possibility to implement an if then else functionality for Mail Server in HTML DB ?
Thanks Tobias

htmldb_mail supports a single mail server per htmldb instance. if you want to call different mail servers, consider sending the emails via your own calls to utl_smtp. there's a pretty simple example of that code at...

Mail Server Woes

Hey All,
I could use some help debugging Mail on my Mac Mini Server (10.8.2 - All updates installed). Two issues going on: mail is not arriving in the inbox and outgoing mail sent from the server does not arrive at the destination - it doesn't matter if its addressed to an internal email or an outside (gmail) account. I can authenticate with the server fine. All the appropriate mail ports are open (25, 110, 143, 587, 993, 995) on the Airport Extreme. I've tried turning off the Junk Mail settings and it made no difference. I'm open to ideas on where to start trouble shooting? If its helpful, I can include the postfix.conf file.
Mail Server: mail.eclimb.org
Any ideas?

You need to look at your logs, if things are failing that is the first place to start to see what the system is reporting.
Look at IMAP Log, Mail Server Log, SMTP Log in logs section of Server app.
Also BTW your external DNS name for your mail server is 'mail.eclimb.org' but your server hostname looks to be 'sawtooth.eclimb.org'. Your server may not like that fact and also RFCs state & DNS best practices advise not to use CNAME alias for mail server machine. CNAMEs are OK for things like web & FTP but not SMTP (the MX record).
See restrictions section in http://en.wikipedia.org/wiki/CNAME_record
Anyway look at your logs first while you are doing test emails:
in from Internet,
out from LAN and
between two email addresses in your domain using two hosts inside your LAN (i.e. message never goes out to Internet).

ColdFusion Splendor mail server verify error

Thanks in advance, Carl.

Hi Carl,
This works for me. Here is my mailsent.log

It verifies the connection for me, successfully as well. Can you try an alternative machine?

Mail Server Configuration in Planning

Hi,
We have installed all the Hyperion Products and developed a planning application.
Now we want to configure the mail server.
Do we need to run the Configuration Utility for mail server configuration or any other way to configure the mail server?
while running the configuration utility, if we use the existing RDBMS tables instead of dropping or creating new table....our application will retain or will it cause any problem to our exsting application?
Thanks,
Naveen Suram

Hi,
If you just talking about the email functionality within planning then you can set it up in planning itself.
Log into the application as an admin owner, administration > application settings > enter SMTP server in the Email Server section. save.
File > Preferences > Enter Email-address and Enable E-mail notification.
Cheers

Simple question; Mac Server Setup for Mail, iCal and Address Book Services.

Hi Guys;
I'm new to the Mac Server world and need a few questions answered.
I have purchased a new Mac mini Server for hosting File, Web, Mail, iCal and Address Book Services.
I’m comfortable setting up File and Web Services however I’m a bit uneasy setting up Mail, iCal and Address Book services to be access locally and remotely(via the internet).
My current setup is;
Internet connection (Dynamic IP) -> Router -> Mac mini Server.
I have purchased a domain name (Thornton-net.com) from DynDns.com + a custom DNS service as I can setup my router to update my domain’s IP address automatically.
I can access File and Web Services remotely (thortnon-net.com) perfectly without any issues via the Port Forwarding feature of the Router.
If I setup Mail, iCal and Address Book Services -> will Mail, iCal and Address Book clients be able to access these services hosted by the server via Thornton-net.com?
Message was edited by: Allan.Thornton

Welcome to the forums.
For mail services (and specifically for your outbound mail to be accepted by other mail servers) your mail server needs to have a static IP address and matching forward and reverse and MX records, or a tunnel to a static IP (with matching DNS), or you need another mail server where you have an authorized relay. Without that, your mail will be considered a spam engine, and dropped.
Additionally, your particular tier of service with your ISP (with a static IP) will generally allow server-oriented access and server-oriented network traffic, where a residential or other tier of service (with a dynamic IP addresses) can be firewalled.
The ISP controls the "high ground" of the network connections here, so you pretty much get to play by their rules and requirements. If they don't offer static IP, then (presuming their T&Cs permit it) you get to tunnel (via IPv6, for instance) to a tunnel broker, and receive your network traffic via that (and with matching DNS) point of presence. That could well be a tunnel for your mail at whichever your DNS provider is here, because you'll have issues with your dynamic address. (You get to sort out if they offer that.)
Far and away the easiest approach (if you want to host this stuff yourself) is to work with the ISP. They're inherently involved in your network, and they and they alone have full control over your reverse DNS configuration.
