Spam Filters

[AbbieRose]

If you provide email addresses for your hosting clients, do you also provide spam filters for them? If so, how do you handle the fact that some filters incorrectly mark things as spam-and hence they may be losing stuff without knowing?

I provide email to my clients and have spam filter but haven't had a problem with the spam filter filtering the wrong email. I imagine there is a option to allow emails and not mark them as spam.

I do not see many providers out there that will do this and if they do most times they either provide it if the client wants it they will request it and its an extra fee. I never see many that market for it though since there are so many user side places out there as far as competition goes.

Isn't managing an email inbox (and spam folder) the client's responsibility?

What TheHostingTeam said is true. The client would be responsible for their inbox. Also, most of the time, their able to look through spam emails, so if the client isnt lazy, then they would find emails that are important in no time. I get important emails through my personal email that get tucked away in my spam folder. It is not hard to glance over them.

Most of the control panels are having spam filters and if you can enable this it will protect some way.

But i found that the Cpanel spam filter never work, always the mail box is full of spam mails. This case is opposite in Direct admin related servers,

The client should be responsible for their inbox, and most control panels will have some form of account-specific spam filtering tools. However, filtering at the server level can decrease the pounding your network takes, and can make your clients' lives seem easier - they have fewer spam filters that they've got to put in place.

It takes research; but you can use a number of RBLs to create your server-side filters.

Just err on the side of caution, when in doubt about an IP let that traffic through - and if you've got a support database or FAQ, let clients know to contact you if they discover that they're not receiving someone's email when they want to receive it. You can whitelist the domain or IP address, and still block any other potential junk that tries to get through from that sector.

We block almost 85% of all mail that goes to our network as it's spam from known RBL's etc. users do have the option in SpamAssassin to tighten things for themselves, but we weed out the obvious to help cut down the traffic in the network and also decrease the load on servers. Letting SpamAssassin or ASSP or other software filtrer do all the work can drive the load up on the server.

Hardware filtering is even better (if you can aford it, and have the resources). You can even do GreyListing for users if they want, but I'd recommend GreyListing for Personal Users rather than Business Users.

Cpanel is more prone for this kind of spam in my experience is it same with others? or it depends on server to server

 

[handsonhosting]

In our case it really depends on the client. We run a number of servers with NO control panel (they're stripped down servers for performance), and they still get spam. The popularity of the site, the number of places an email is listed, and how they send out newsletters etc are all contributing factors. We sell much less spam on a server with only 10 customers, than we do with a server with 100 customers. This is to be expected. I've not seen the control panel play a part in spammers activity. cPanel may get blamed because it is so popular, but I don't believe it's a contributing factor.
