Mail stucked in /var/spool/mqueue

Problem:

mails get stucked in /var/spool/mqueue
Note: If this document does not resolve your problem, please check or troubleshoot your sendmail.cf configuration file.

Solution:

nimserver(/usr/spool)#ls -ld /var/spool/mail

drwxrwxr--    2 bin      mail            256 Feb 04 13:39 /var/spool/mail

nimserver(/usr/spool)#

After changing permission of /var/spool/mail to 775.

nimserver(/usr/spool)#ls -ld /var/spool/mail

drwxrwxr-x    2 bin      mail            256 Feb 04 13:39 /var/spool/mail

nimserver(/usr/spool)#

Check how many mails get stuck, in my case its just two..

nimserver(/var/spool/mqueue)#ls -ltr

total 40
