UNIX From Command Prints Mailbox Header Lines
The /usr/ucb/from UNIX command prints out the mail header lines in your mailbox file. It shows you who the mail is from. Here is an example run for this command.

Setup Mail Client on UNIX-based System
In the last post, a mail server setup was demonstrated. This post will demonstrate the setup of a mail client. Again, the setup of mail client is fairly straightforward. Here is the run.
On the client side, ensure the /var/mail directory is present.
# ls -l /var/mail
If not, create it.
# cd /var
# mkdir mail
Now modify the client's /etc/vfstab file
# vi /etc/vfstab
esoft:/var/mail - /var/mail nfs - yes -
:wq!
Now mount /var/mail
# mount /var/mail
Verify the /var/mail is actually being shared from the mail server
# cd /var/mail
# df -k .
On the client side, ensure the /var/mail directory is present.
# ls -l /var/mail
If not, create it.
# cd /var
# mkdir mail
Now modify the client's /etc/vfstab file
# vi /etc/vfstab
esoft:/var/mail - /var/mail nfs - yes -
:wq!
Now mount /var/mail
# mount /var/mail
Verify the /var/mail is actually being shared from the mail server
# cd /var/mail
# df -k .
FEATURE_ERROR_USER_OPEN_NO_ACCESS
As I do practically every morning along with millions of others around the world, I logged into my Yahoo.com email account to check mail. To my chagrin, I was unable to login, and to make matters worse, my user ID/password combination wasn't recognized by the system. My first thoughts were "CAPS LOCK," or forgotten (which I rarely do) password , or hacked, or TOS violations (on what basis??) or corrupted cookies – who the heck knows. Then I decided to have my password recovered to an alternate email address (gmail), but I was still darn sure I knew my password. For “you know what and grins,” I made an attempt to recover it. But my user ID wasn't even recognized by the system. Here is the message I received after entering my user ID and answering a question about ever using a credit card or not.

Sorry That You're Having Trouble Signing In
We know that not being able to sign in can be frustrating, so we'll try to make this as quick and easy as possible. To get started, enter your Yahoo! ID and let us know if you've ever used a credit card with Yahoo!.

I wasn't too sure what the aforementioned cryptic error message was all about but it didn't look promising.
So I decided to recreate the email account, maybe there was a simple glitch in the system. No joy because it's not available. Someone else is using it - Yes, it's ME!
After traversing Yahoo’s help pages for awhile, I finally found the customer care form and submitted my problem. I let them know the account was tied to my PAID Yahoo MyBlogLog Account (for meta data and stats) and I was NOT spamming or using the account for any illicit activities, so I asked them to please explain why my account has disappeared into the ether.
After all that, I tried logging in again but no joy.
So now I decided it was time to Google for the answer. Here is what I found from Yahoo's answers via the Google index.
“the solution for this problem is to go to the yahoo! India web page and try logging in through that ..........”
So I brought up the yahoo.co.in homepage and grudgingly logged in. Whoa! It worked.

Troubleshoot POP3 Mail Server with Telnet
I am finally getting an opportunity to write a post. I have been so busy with upgrades lately and had to put off writing for awhile.
The other day I had a number of users complaining about not being able to fetch mail to their mail client, MS Outlook. As usual, I attempted to duplicate the error. The error message was reporting unable to connect to the mail server. At that point, I decided to telnet the Post Office Protocol or POP3 port, 110, via the command line interface. Sure enough, I had a problem.
Note: The “before and after” command line examples are only for illustration purposes.
# telnet server 110
Trying 192.1xx.xx.xxx...
telnet: Unable to connect to remote host: Connection refused
I started thinking there was a problem with the inetd.conf file. After reviewing the file, I noticed the pop3 service was commented out. The appropriate change was made and inetd was restarted. Problem resolved.
# telnet server 110
Trying 192.1xx.xx.xxx...
Connected to server.
Escape character is '^]'.
+OK connected to pop3 on 3429
By the way, you can check out other popular port services, too.
# telnet server 6667
# telnet server 25
