I have been working at setting up TLS/SSL on my Debian/Postfix mailserver and installing a CA-verified certificate. Yesterday I made a few tweaks, and suddenly found that on one account I was not getting any messages via POP. I was still able to access the account e-mails via IMAP but lost POP access - no error message, but "no new messages on server", despite the fact that there were. I looked at the /var/mail directory and discovered that my e-mails have suddenly begun being stored in my Home directory mbox. All other accounts seem to be working fine . . . Any suggestions on what to look at? I will post main.cf and other pertinent info if anyone wants to review them.
Follow-Up The issue seems to be that none of the accounts can access their POP mailbox. I can send a mail and see it being received, and the mail file gets updated, but POP access returns "no new messages" to the client. I can read the messages on the machine with the mail program. How does postfix provide POP access to users checking their mail? And what would interfere with that?

Postfix is a delivery agent, if i'm correct, and therefore should maintain only delivering messages to users as well as sending yours to others. On my mailserver, I have a Dovecot, which provides me with pop3 and imap access to the mailbox. Maybe you disabled daemon, which was responsible for pop3 connections. Are you even capable of connecting to the server via pop3?
Fixed Problem solved. One beauty of clicking around the internet is the ability to meld multiple approaches that each function beautifully into a single solution that fails miserably. /etc/procmailrc (new file created to solve some problem on Sunday) ORGMAIL=$HOME/mail DEFAULT=$ORGMAIL I cannot even remember what I was trying to fix when I did that - I know I was in a hurry to get to the theater to see "Inception" . . . :-/ Removed file, e-mail works! Thanks!
