Block Images/Links

Outlook has a pretty good feature when opening emails with images and/or attachments where it will block the images and prevent users from clicking on the links until the user clicks a link at the top saying that the email is safe. I was wondering if MailEnable has a feature similar to this? I've lo...

Re: Block repeated failed connections by IP

To take this setting a step further in the "Smart" direction, any accounts blocked by an IP address that has been banned for these actions would be automatically unlocked since the attacker has been banned.

Re: Fighting Hackers

Blocking IP addresses on SMTP would be a good solution. The best way that I can think of to block these is to have something that will block failed connection attempts by IP address. ME would count each consecutive failed login attempt by the IP address rather than the username, so lets say users a...

Re: Fighting Hackers

I have the same issue is tomr, even though i have the ylmf-pc blocked, but thats not the only attacker, there are several others with varying EHLO/HELO names after it. It seems as though the computer name after EHLO/HELO commands, the IP addresses, and the usernames they login with are completely ra...

Block repeated failed connections by IP

More often than not, hackers try multiple accounts one after the other until the account is blocked, then they move onto another set of user names until blocked, then another, and another, and another. The problem with this is the accounts are being blocked, not the attacker, but the purpose is to b...

Re: Fighting Hackers

Apparently I did block this and completely forgot. I used EHLO blocking in the SMTP properties > Security Tab > Configure Blocks. No wonder they disappeared! :lol:

Re: Fighting Hackers

Does the actual abuse (the one with repeated attempts) seem to come from the same class C IP address? Does it appear to come from a specific geography? You can enable the Windows firewall to help with these attacks from these ideas. My list contains classes A, B, and C IP addresses, no multicast IP...

At one point, i needed the attachment so i clicked it to download it, and after viewing the attachment, webmail had disconnected me. Does downloading an attachment not count towards activit...

Re: Invalid Email Account Login Attempts

I believe it... For the last couple years i've been using MMC. I add the IP Security Policy Management snap-in and block IP's through there. There's several problem with this: 1) It doesnt notify you if you are entering a duplicate. I dont see duplicates happening but if the filters were to fail for...

Re: Invalid Email Account Login Attempts

MailEnable does block the IP address for up to 1 hour. Another way of doing it if it is the server is to use RDPGuard. Don't let the name fool you as it can block other forms of connections to the server. With this, you can set it up to block IP addresses for as long as you want before it auto dump...

Re: Invalid Email Account Login Attempts

I still havent found a solution to this but I do have a simple feature request that could resolve this. One way people are bypassing the protection is by trying hundreds of DIFFERENT names. So since they failed logging in as root, they try postgres, fail again and they try admin, fail again and they...

Opening Junk Mail

I have version 8 and was wondering if there's an option anywhere that makes it so that when you open email in the junk folder, it blocks images and links? For example, junk mail that has images attached to a specific image on the hosted site will load, indicating to them that you have an active emai...

Re: Looking for suggestions regarding this spam

Thank you Ian!

Do you know if this bad practice to do? Or with this mail client, is this actually a good practice?
