IMAP (Internet Mail Access Protocol) mail server uses this port. See also port 993/tcp.
Numerous IMAP servers have buffer overflows that allow compromise during the login. Note that for awhile, there was a Linux worm (admw0rm) that would spread by compromising port 143, so a lot of scans on this port are actually from innocent people who have already been compromised. IMAP exploits became popular when Red Hat enabled the service by default on its distributions. This port is also used for IMAP2, but that version wasn't very popular. Several people have noted attacks from port 0 to port 143, which appears to be from some attack script.
MailServer.exe in NoticeWare Email Server 4.6.1.0 allows remote attackers to cause a denial of service (application crash) via a long string to IMAP port (143/tcp).
References: [CVE-2008-1713] [BID-28559] [SECUNIA-29629]
Format string vulnerability in the University of Washington (UW) c-client library, as used by the UW IMAP toolkit imap-2007d and other applications, allows remote attackers to execute arbitrary code via format string specifiers in the initial request to the IMAP port (143/tcp). NOTE: Red Hat has disputed the vulnerability, stating "The Red Hat Security Response Team have been unable to confirm the existence of this format string vulnerability in the toolkit, and the sample published exploit is not complete or functional." CVE agrees that the exploit contains syntax errors and uses Unix-only include files while invoking Windows functions.
