Nghẽn mail trên kloxo

Nghẽn mail trên kloxo

Đăng nhập vào quản lý host kloxo, chọn menu Web - Mail - Database => Mail Queue =>  để xem những mail gửi đi spam -> click vào chi tiết để xem email spam -> disable host spam, sau đó ssh vào chạy những lệnh bên dưới để xóa mail bị nghẽn. nếu vào Mail Queue bị treo thỉ cũng phải xóa những lệnh bên dưới.

ssh vào server gõ lệnh sau:

 /var/qmail/bin/qmail-qstat  nhấn enter sẽ hiện thị như sau:


Output looks like

messages in queue: 567154
messages in queue but not yet preprocessed: 3

Xóa:

qmailctl stop
find /var/qmail/queue/mess -type f -exec rm {} \;
find /var/qmail/queue/info -type f -exec rm {} \;
find /var/qmail/queue/local -type f -exec rm {} \;
find /var/qmail/queue/intd -type f -exec rm {} \;
find /var/qmail/queue/todo -type f -exec rm {} \;
find /var/qmail/queue/remote -type f -exec rm {} \;
qmailctl start

Disable local mail (Kloxo )

Để tránh IP server bị ảnh hưởng như nghẽn mail, IP bị các tổ chức chống spam mail quốc tế liệt IP vào blacklist, chúng tôi cần tạm ngưng dịch vụ mail client spam mail


1 - Vào 7778 -> mục client -> phần qmail -> Remote mail -> set Remote

2 - SSH server Xóa domain trong file virtualdomains (nếu còn)

/var/qmail/control/virtualdomains

Ngoài ra nếu bạn dùng mail server nơi khác vd mail gmail và gửi đi không được vì hệ thống lầm lẫn với mail local. Bạn cũng có thể dùng cách trên để khắc phục.

Chúc bạn thành công.

Exim Remove All messages From the Mail Queue

Question:

 I'm using Exim mail server under CentOS Linux. How do I remove all messages from the Exim mail queue using a shell prompt?

Answer:
Exim is a mail transfer agent (MTA) used on Unix-like operating systems. It aims to be a general and flexible mailer with extensive facilities for checking incoming e-mail.

To print a list of the messages in the queue, enter:

# exim -bp

To remove a message from the queue, enter:

# exim -Mrm {message-id}

To remove all messages from the queue, enter:

# exim -bp | awk '/^ *[0-9]+[mhd]/{print "exim -Mrm " $3}' | bash

Dallas Marlow, suggested following clean command:

# exim -bp | exiqgrep -i | xargs exim -Mrm

DELETE FROZEN MAILS

/usr/sbin/exim -bp | awk '$6~"frozen" { print $3 }' | xargs /usr/sbin/exim -Mrm

REMOVE MAILS FROM SENDER

/usr/sbin/exiqgrep -i -f (MAIL ADDRESS HERE) | xargs /usr/sbin/exim -Mrm 

OR 

/usr/sbin/exim -bp | awk '$4~"info@domain.com" { print $3 }' | xargs /usr/sbin/exim -Mrm

Install ConfigServer Apps On A cPanel/WHM Server

ConfigServer provide a range of paid and free applications, including a significantly more advanced firewall, that plug directly into WHM on your cPanel server. These applications are highly recommended for anyone who is serious about the security of their cPanel Server, as they not only provide enhanced security functionality, but also allow you to easily manage a number of other basic cPanel functions, such as mail settings, mail queues, and a more advanced ModSecurity tool.

Below is a list of the free applications that we will be providing the simple installation instructions for:

1. CSF - this is an advanced firewall system utilising Linux ip tables
2. Mail Manage – allows you to adjust mail settings, such as hourly limits and email forwarders, on a per account basis
3. Mail Queues – easily manage your email queues with the ability to force run the queue and delete stuck messages
4. ModSecurity Control – if you have installed ModSecurity on your cPanel Server, this provide an advanced management interface
5. Explorer – This is a file system explorer web interface which allows you to also run basic shell commands within folders – WARNING: While this utility can be very useful it is also very dangerous indeed. You can easily render your server inoperable and unrecoverable by performing ill advised actions. No warranty or guarantee is provided with the product that protects against system damage.

NOTE: All of the installations below require you to be logged into SSH as root.
