Why email blocking doesn't work.

[garygan]

Hi. I'm using WFilter Enterprise trial version and I have some question regarding blocking email.



1. I noticed from the page that there are 3 settings:



Enable Black/White List for Local Email Senders

Enable Black/White List for "To" addresses of Email Sending

Enable Black/White List for Local Receivers



May I ask what do all these 3 features do?



2. Even with the blocking sending email with attachment option enabled, I can still send email with attachment(s)?



3. When I entered abc@gmail.com in the Email Black list, and enabled 'Enable Black/White List for "To" addresses of Email Sending', I can still received the email sent for abc@gmail.com.

WFilter has three "Email black/white list" to filter email sender/receiver account.

However, the "email black/white list" only can filter POP3/SMTP/IMAP emails. Web-based email can not be filtered.



As you know, "gmail" is web-based email, so you can not use "Email black/white list" to filter it.

The 'Enable Black/White List for Local Email Senders' option doesn't seems to work for me. Even though I had included abc@company.com in the email blacklist, I'm still able to sent out email using the email account. The email sending options 'with attachment' also doesn't seems to work.



I wonder does it matter if I'm connected through wifi adapter?

You may use a wifi adapter, however, WFilter shall do monitoring/filtering on a wired NIC. Are you using SMTP to send email? Or web-email?

Problem solved. It turned out that Enterprise version 3.3 and below doesn't support SMTP port 587.

Great. SMTP port 587 is supported from build "en.3.3.185".
