<div class="content wysiwyg-content">
I have a Solaris 2.8 server running qmail 1.03 for about 1100 users.<br />
<br />
I want to specifically target certain user accounts from being able to access their Mailbox but I do NOT want to impede them from receiving messages.<br />
<br />
I need to be able to disable a user from telneting into the server, using any of the installed web mail interfaces: &nbsp;Roundcube, IMP/Horde, &nbsp;and Twig, or getting their e-mail messages using their preferred mail client that is set up for IMAP or POP3.<br />
<br />
Again, these users MUST continue to receive messages stored in their Mailbox but may NOT access them.<br />
<br />
How would I accomplish this feat?

Disable Users from Accessing qmail Messages

Unix is a multitasking, multi-user computer operating system originally developed in 1969 at Bell Labs. Today, it is a modern OS with many commercial flavors and licensees, including FreeBSD, Hewlett-Packard’s UX, IBM AIX and Apple Mac OS-X. Apart from its command-line interface, most UNIX variations support the standardized X Window System for GUIs, with the exception of the Mac OS, which uses a proprietary system.
