Why can't I reply with POP email address?

Question

Hello, I have a problem.
I have just set up a new POP account and I also have a .mac account. My POP account is my work email so ideally it would be handy if when somebody emails my work account, when I reply, I reply with my work email address as opposed to my @mac address. Any ideas? Have I set it up wrong? Also, is there any way in which I can direct my POP emails into a specific folder?
I am a new Mac user, have been using Windows for years (have now seen the light!!)

Hello Vonnie.
When replying to or forwarding a message received by a particular account, the account the message was received by should be the default sending account and email address for the message.
Go to Mail > Preferences > Accounts and under the Account Information tab for the POP work account, what is the email address entered in the Email Address field for the account?
When opening "In" in the mailboxes drawer by selecting the black triangle beside it pointing it down will reveal the account named Inbox mailbox for each account. When selecting the account named Inbox mailbox for your POP work account will reveal messages received by that account only in the message list. When selecting "In" in the mailboxes drawer reveals a "blended" Inbox mailbox for all accounts in the message list.
The same applies under Drafts, Sent, Trash and Junk (if you have Junk Mail set to automatic) in the mailboxes drawer.
You can utilize user created "On My Mac" mailboxes which are stored locally on the hard drive and create a rule or multiple rules in Mail to sort received messages to user created "On My Mac" mailboxes by category.
To create a mailbox, at the menu bar go to Mailbox and select New Mailbox. The default location is "On My Mac" and if you have a .Mac or IMAP type account, you can also create server stored mailboxes.
Enter a name for the mailbox and when finished, select OK. The user created mailbox will be available in the Mailboxes drawer. It will appear as a folder but is actually a mailbox. You can nest mailboxes within other mailboxes if desired. You can manually move a received or sent message from an account's Inbox or Sent mailbox to a user created mailbox or as previously provided, create a rule to automatically transfer received messages to a designated created mailbox by category.
