I have been searching and searching this forum for the answer. I am horrible with Linux, so please bare with me.

Internal employees at my company can log on and check their email as long as they are on the domain. However, they can not configure outlook at home to get their email. The person I replaced in this position was a security freak, which I fully agree with; however, he didn't want anybody the ability to get their email from home.

I have a Linux mail server running postfix/sendmail. My DHCP and DNS servers are Windows 2003 Server. I have a Cisco Router. If you have any questions on my setup, I will be happy to answer them. My email is pennstatemtnman@yahoo.com I am getting really desperate and I need the help to get this up and running for the people working out of their house.

If he wasn't allowing anyone to retrieve mail from outside the network then most likely port 110 (POP3) is blocked at the firewall..

You would need to forward port 110 from the firewall to the mail server.

You would probably also want to setup some sort of authentication to prevent people from outside sending mail through your server without authenticating first.. like pop before smtp or requiring TLS auth for sending and receiving. etc.. Because if you are going to let them retrieve mail from outside they are going to want to send from outside and there go your network based restrictions that are probably configured on yur mail server now..


I do not allow my users to connect to the mail serverfrom outside the nettwork with a client like Outlook either. but I do provide them access to their email through a webmail server from outside..

Definately makes sense. Do you know of any way to get a cell phone to send and recieve emails without lifting the security.

I suspect you would need to put some sort of webmail solution in place.

I do have squirrelmail in place.

Squirel mail works but is really clunky through a phone.

I actually am planning to rebuild my mail server and add in smtp auth using tls and quotas, etc.. I'm planning to use this recipe http://www.howtoforge.com/virtual_po..._quota_courier it doesn't vary too far from what I am already doing, and adds in some features I would like to have (Auth and Quotas for one) and I want to replace my squirrelmail with something a bit nicer while I'm at it.

Yes providing the execs direct access to the mail server from their Treo's is something they desperatly want. All I'm waiting for is the aproval for the new hardware.. and waiting, and waiting.. but at least this way every time they complain I tell them it will be fixed in the new mail server and ask them if I can order the hardware.. I guess it's not so big an issue since they don't want to spend the money to address it..

the old PIII 550 thats running the current mail server is tired it really wants to retire.. I'm just afraid it's going to retire on it's own before I get to replace it..

How were you able to get the email on the phone via squirrel mail?

The phone has interet access and a web browser... not so hot..

I thne configured Postfix to forward all mail going to the account to the Email address of the phone.. but then the pphone gets all the spam etc as well.. not a good solution either.

Imap access will be better but they aren't getting that until I get anew server.. (It's the only leverage I have since they are being stubborn )

You may also need some third party software: Goodlink is used where I work for this sort of thing.
