SELinux heads up...

[Eric Hunter]

If you happen to be still using Courier and Qmail, the SELinux update for CentOS 7 will SMTP and IMAP functionality for Plesk 12.5. Disabling SELinux was the fastest way I could find to fix it. I assume there will be a fix from Odin shortly for it.

Could you please provide more detail of this issue?

P.S. We are not Odin. We are Plesk (https://plesk.com)

After running an OS update, it updated selinux-policy and selinux-policy-targeted. After that IMAP and SMTP connections failed. audit log showed:

type=AVC msg=audit(1455928843.778:7419): avc: denied { sigchld } for pid=1213 comm="xinetd" scontext=system_u:system_r:qmail_smtpd_t:s0-s0:c0.c1023 tcontext=system_u:system_r:inetd_t:s0-s0:c0.c1023 tclass=process

This was a new server install, but we'd migrated 140+ domains over.

Try to reinstall psa-selinux package after OS update.
