Dears,
We have a mail server (RHEL 6.0, Postfix and Dovecot 1.0.7).
The output of dovecot -n is the following:
# 1.0.7: /etc/dovecot.conf
protocols: pop3
login_dir: /var/run/dovecot/login
login_executable: /usr/libexec/dovecot/pop3-login
mail_location: mbox:~/mail:INBOX=/var/mail/%u
mail_executable: /usr/libexec/dovecot/pop3
mail_plugin_dir: /usr/lib/dovecot/pop3
pop3_client_workarounds: outlook-no-nuls oe-ns-eoh
auth default:
passdb:
driver: pam
userdb:
driver: passwd
During the last days we face the following problem:
There is great delay in the delivery of the emails. Some seem to not be
delivered at all. Issuing the mailq command we get the following message for
almost all the email accounts:
(cannot update mailbox /var/mail/xyz for user xyz. unable to lock for
exclusive access: Resource temporarily unavailable)
Please send to me any suggestions, because I cannot resolve it and I receive
a lot of pressure.
Best Regards,
Nikos
