For security reasons, our web server is blocked PORT 25. Every website can only send email via SMTP with PORT other than 25.

You may use third-party SMTP server. For example, use Gmail's SMTP server (smtp.gmail.com) via PORT 465 or 587.

You may use our SMTP server smtp.techubs.com too. Before you use our SMTP server, please create an email account at Web hosting admin panel, then use the created account information at your web program, make a connection to our SMTP server via PORT 587 to send email.

On our shared hosting environment, the maximum upload file size using PHP is limited to 256MB.

On our VPS hosting enviroment, the maximum execution time is default to 256MB. However, you may customize it by uploading a php.ini file into the web server root directory. For example, to update the maximum upload file size to 1GB, upload a file named php.ini into your web server root directory with the content upload_max_filesize=1024MB and post_max_size=1024MB.

On our shared hosting environment, the maximum execution time is fixed to 60 seconds.

On our VPS hosting enviroment, the maximum execution time is default to 60 seconds. However, you may customize it by uploading a php.ini file into the web server root directory. For example, to update the maximum execution time to 300 seconds, upload a file named php.ini into your web server root directory with the content max_execution_time=300.

Both IMAP and POP3 server are used by clients to retrieve their emails. However, they are different.

When you use POP3 to get your email, the email will be downloaded to your device and the server copy will be deleted. You can read your emails anytime with/without Internet connection.

The advantage of using POP3 is that

• All email will be downloaded to your device and you can read it at anytime even you are not connected to the Internet.
• You will not occupy too many spaces on the server. Only the new email will be kept on the server.

The disadvantage of using POP3 is that

• Only one device can be used for each account. It is because the second device using the same account will not be able to get the same email if the first device has downloaded it.
• You need to backup your email by yourself.

When you use IMAP to get your email, only the email header parts (eg. email subject, email from address, email to address etc..) will be fetched to your device. The body part of your email will only be downloaded when you read the email, therefore, you can only read your email while you are connected to the Internet. The original email will be kept on the server forever until you manually instruct the server to delete it.
Besides, IMAP supports adding flags (eg: Seen, Answered, Flagged, Deleted, Draft) to the email message while POP3 do not.

The advantage of using IMAP is that

• Several devices can share the same account.
• You do not need to backup your email.

The disadvantage of using IMAP is that

• You have to access your email while you are connected to the Internet.
• You need to clean your mailbox regularly to prevent your email quota at the server from getting full.

For email processing, we provide two servers for client to access, one for receiving email and one for sending email. They are pop.techubs.com and smtp.techubs.com respectively. If you setup your email using these two servers with SSL or TLS connection, you will NOT get the alert message because the certificate used on our servers are using the common names pop.techubs.com and smtp.techubs.com, which are matched to the hostnames you specified.

However, if you use your own domain name as a suffix for accessing the email servers, for example, if your domain is hkbizs.com and you use pop.hkbizs.com and smtp.hkbizs.com to access our servers, you will get the certificate verification failures message. It is because the names pop.hkbizs.com and smtp.hkbizs.com are just alias names for our server pop.techubs.com and smtp.techubs.com. These alias names are not matched to our certificate common names.

To fix the problem, you have three options:

1. Use pop.techubs.com and smtp.techubs.com instead
2. Do not use SSL or TLS connection
3. Ignore the alert message and continue use your domain name suffix
