How to setup email on your iPhone or iPad

Re: Setup email on iPhone, iPad, iPod or IMAP PC/Mac client

So you have logged in to Plesk and created your mailbox. Now, apart from being able to use RoundCube Webmail straight away, you might want to connect your cool iDevices too. Here’s how to do it…

Try the following for sending/receiving IMAP on your iPhone/iPad or Mac/PC devices:

Incoming Mail Server
Hostname: mail.yourdomain.co.uk
User Name: mailboxname@yourdomain.co.uk
Password: (your password)

A certificate warning may be displayed, please click on Details -> Trust to continue. This will allow you to use your shared hosting server SSL certificate to connect securely to your mail account.

Advanced Incoming Settings
Use SSL: ON
Authentication: Password
IMAP Prefix: INBOX
Server Port: 993
S/MIME: OFF

Outgoing Mail Server (SMTP)
Hostname: mail.yourdomain.co.uk
User Name: mailboxname@yourdomain.co.uk
Password: (your password)
Use SSL: ON
Authentication: Password
Server Port: 587

Obviously replace mailboxname@yourdomain.co.uk with your own actual mail box name and yourdomain.co.uk with your actual domain name. Now you should be able to send and receive without any problems.

How to find an anonymous spammer on a Plesk server

Re: Finding Plesk Spammer, Qmail spam source, Anonymous spam

So you’ve done all the basics, looked through the maillogs and you’ve determined the spammer is sending from “anonymous” which means a vulnerable script somewhere on the server. But where? Great, so now let’s delve a little deeper to find the UID of the spammer.

1) Let’s take a look in the mail queue and read one of those spam email references:

# /var/qmail/bin/qmail-qread

remote ankush_krishna2137@yahoo.com
6 Jan 2012 09:14:53 GMT #34012584 2987 <anonymous@server.microlite8.com>

2) Now we have a message ID, let’s search for the actual message:

# find /var/qmail/queue/ -name 34012584

/var/qmail/queue/info/0/34012584
/var/qmail/queue/remote/0/34012584
/var/qmail/queue/mess/0/34012584

3) Great! Now let’s see what’s in the message to get out that all telling UID:

# cat /var/qmail/queue/mess/0/34012584

Received: (qmail 9936 invoked by uid 10820); 6 Jan 2012 09:14:50 +0000
Date: 6 Jan 2012 09:14:50 +0000
Message-ID: <20120106091450.9934.qmail@server.microliteX.com>
To: annette@recdom.wandoo.co.uk
Subject: Urgent Reply
From: Mrs.Farida Waziri <faridawaziri@hotmail.com>

4) Let’s map the UID to a domain name on the Plesk server:

# cat /etc/passwd | grep 10820

admin947932:x:10820:2523::/var/www/vhosts/thisisthespammer.com:/bin/false

5) Spammer caught 😀

How to block Yandex using IPTABLES or APF

Re: Yandex IP range, Yandex subnets, Block Yandex Robots

Across our server range we are finding that Yandex continues to ignore robots.txt files and crawls some sites constantly, so how do you stop such an abuse of your network resources?

If you use IPTABLES or APF (you should!) then you can block all Yandex spiders using the following IP ranges:

77.88.0.0/18 # yandex.ru
77.88.22.0/23 # yandex.ru
77.88.24.0/21 # yandex.ru
77.88.24.0/22 # yandex.ru
77.88.28.0/22 # yandex.ru
77.88.36.0/23 # yandex.ru
77.88.42.0/23 # yandex.ru
77.88.44.0/24 # yandex.ru
77.88.50.0/23 # yandex.ru
87.250.224.0/19 # yandex.ru
87.250.230.0/23 # yandex.ru
87.250.252.0/22 # yandex.ru
93.158.128.0/18 # yandex.ru
93.158.137.0/24 # yandex.ru
93.158.144.0/21 # yandex.ru
93.158.144.0/23 # yandex.ru
93.158.146.0/23 # yandex.ru
93.158.148.0/22 # yandex.ru
95.108.128.0/17 # yandex.ru
95.108.128.0/24 # yandex.ru
95.108.152.0/22 # yandex.ru
95.108.216.0/23 # yandex.ru
95.108.240.0/21 # yandex.ru
95.108.248.0/23  # yandex.ru
178.154.128.0/17 # yandex.ru
178.154.160.0/22 # yandex.ru
178.154.164.0/23 # yandex.ru
199.36.240.0/22 # yandex.ru
213.180.192.0/19 # yandex.ru
213.180.204.0/24 # yandex.ru
213.180.206.0/23 # yandex.ru
213.180.209.0/24 # yandex.ru
213.180.218.0/23 # yandex.ru
213.180.220.0/23 # yandex.ru

Simply restart APF and Yandex will no longer be a problem (until they extend their network!).

Which SMTP server should I use to send email?

Sending Emails using SMTP

Many of our hosting accounts are provided with your own shared SMTP server based on your domain name however many ISPs are now blocking 3rd party SMTP use in an effort to control SPAM on their networks.

If you use a third-party SMTP server server based on your domain name it may be classed as a spam risk. Sometimes, only emails sent through a dedicated ISP SMTP server have the best chance of delivery.

Use your ISP SMTP Server for best performance

When to use mail.yourdomain.co.uk

Most of our tutorials show your email configuration using the SMTP server mail.yourdomain.co.uk, however, you should use your ISP SMTP server in its place for the best and most consistent results.

If your ISP does not provide you with an SMTP service, then try using mail.yourdomain.co.uk as your SMTP server, this will work for most email networks.
