cPHulk protection

[DavidAllen]

Hi
I have a cloud VPS with cPHulk protection turned on. I'm running into a problem when customers try to configure email.

In Outlook you enter the email address and password, then Outlook tries to determine the server settings to set up the account.

Normally, it first tries encrypted, which it always fails on (why??) then it tries unencrypted which it succeeds on.

However with cPHulk turned on the first step (encrypted) triggers the security and the IP attempting to connect gets shut out from the server. The next step (unencrypted) then fails due to the block on the IP.

So the upshot is my customers can't get their emails set up (unless all the settings are entered manually).

If I whitelist the IP then the email gets setup OK.

I've got the default settings on cPHulk - so why does this happen, and what do I need to change?

Hi David.

It must be an issue with the email client's setting as you said it's working fine with the unencrypted connection. Please make sure that you enable encryption (SSL/TLS) option but not the secure authentication [Secured Password Authentication] as it wont work until configured on the mail server.

Such setting could lead incorrect login attempts and then block ip in the cPHulk protection.
Just try to configure your email client without [Secured Password Authntication] option and let us know if that works.

Hi Kieran
Thanks for the reply. The problem isn't with the manual settings for Outlook. Rather it is the settings that Outlook tries to use when you ask it to create an account - it just asks for email address and password, nothing else, then it tries to set up the account (not sure if it contacts the server to determine the settings or it tries several 'default' configurations until one works), but first it tries encrypted and fails (which I think triggers cPhulk) and then it tries unencrypted which fails due to cPHulk.
If I whitelist the relevant IP in cPHulk then outlook sets up the email account (Unencrypted) just fine on it's own.
