Remove a user 's  mail from queue

remove_mail_in_queue.sh

#!/bin/bash

_USER="USER@YouWantDelete"

for i in `postqueue -p | grep $_USER | awk {'print $1'} | grep -v 'MAILER-DAEMON'`
do
        # remove "*"
        mymail=`echo $i | tr -d '*' `
        if [[ "$mymail" != ""  ]]
        then
                postsuper -d $mymail
        fi
done

Cleanup old mail (over 90 days)

#!/bin/bash
# V0.6
# clean FOLDER on $1
# build a list.sh to run

echo "# clear 90 day before file"
MYDIR=`pwd`

function cleardir {
        FOLDER="$1"

        if [ -d "$FOLDER" ]; then
                echo "#######################################"
                echo "# pwd: $MYDIR"
                echo "# FOLDER: $FOLDER"

                if [ -e "${FOLDER}/cur" ]; then
                        bakdir="${MYDIR}/backup/${FOLDER}.cur.old"
                        src="${FOLDER}/cur"
                else
                        bakdir="${MYDIR}/backup/${FOLDER}.old"
                        src="${FOLDER}"
                fi

                echo "# src: $src"
                echo "# bakdir: $bakdir"
                echo "mkdir -p \"$bakdir\""
                find "$src" -mtime +90 -type f -exec echo 'mv -b ' \''{}'\' \'"$bakdir"\' \;
        fi
}

# folder list
ls -1 -A > myfilelist.txt

while read line
do
        if [ "$line" != "courierimaphieracl" ] && [ "$line" != "courierimapkeywords" ]; then
                echo "$line"
                cleardir "$line" >> list.sh
        fi
done < "myfilelist.txt"

rm -f myfilelist.txt

chmod 700 list.sh

echo "Done"

telnet smtp test script

#!/bin/sh

_SERVER="xxx.xxx.xxx.xxx"

( echo "HELO testing.com"
sleep 2
echo "MAIL FROM:<tim@MyReturnDomain>"
sleep 2
echo "RCPT TO:<tester@TestDomain>"
sleep 2
echo DATA
sleep 2
echo "Subject:Test-Mail!"
sleep 2
echo "Test-Mail!"
sleep 2
echo .
sleep 2
echo QUIT
) | telnet  $_SERVER 25

P.S.

telnet 後沒有待對方 reply 說 helo 及每句只等 2 秒好易出事, 所以這段 script 唔多 work ...

Cleanup orphan mail data

cleanup_orphan_mail_data.sh

#!/bin/bash
# filename: cleanup_orphan_mail_data.sh

# cleanup screen

if [ ! -d $_MailBoxPath ];then
        echo "no mail data"
        exit 1

rm $_MailBoxList $_USERLIST

Check in mailbox

cd /var/vmail/MyDoman/MyUser

find . -type d -name cur -exec ls -1 "{}" \; | wc -l

find . -type d -name new -exec ls -1 "{}" \; | wc -l

Check User Quota on DB

select t1.username, t1.quota, t2.bytes div(1024*1024) from mailbox as t1 join used_quota as t2  on t1.username = t2.username

pop3 uidl 保留失敗時

1) 從 log 找出 pop3 user - pop3_users.txt

2) 將 inbox 的信放到 Folder MigrationArchive

cd /var/vmail

migrate.sh

#!/bin/bash

set -e

while read USER
do
    echo "Fix $USER"
        archive=$USER/Maildir/.MigrationArchive
        inbox=$USER/Maildir/cur
        if [ -d $inbox ]; then
                echo "Move Folder"
                #mkdir $archive
                #mv $inbox $archive
        fi
        if [ -d $archive/cur ]; then
                        echo "Ok"
        fi
done < "pop3_users.txt"
