Shared Hosting Providers, what are your Anti-SPAM measures?
Hey,
Again, I'm looking at some more possibilities, suggestions or recommendations on this topic. Pricing on LET won't buy most providers mailchannel or other outgoing relay with filters. Like Francisco has his own scripts system
I wrote a few script to assist or automate things. One is to get mass senders from exim log and suspend outgoing email for them. Some are for reporting which I no longer use.
Now, what else do you guys use?
Or shall I..

I'm waiting on Mxroute allowing SMTP relay on standard plans
That'd again be costly for high limits than standard plans. Gleert did pretty good sale last Black Friday still doesn't covers it
Will most likely not happen. https://mxroute.com plans are super cheap, often less than $10 / year if you are a light user and only gets them on promotions. If you check https://www.mailchannels.com/reseller/whmcs-module/ , each sub account will cost $1 / month = $12 / year excluding any outgoing emails, so that’s already a loss.
I use mailchannels for email and submit a whole lot of data into influx and ES to spot anomalies - and I actively contact customers when they do stuff that looks semi-spammy.
I'm also not in the LET pricing, so I guess I can afford it.
Depending on how many emails your customers send? I'm sure you can get LET prices as well if you PM Miguel. I'm specifically waiting on being able to use my Mxroute.com account which has unlimited everything but 40GB of storage.
I have Mailchannels on non-LE pricing plans but still gotta look for LE plans. Mailchannels works great tho
I don't think it can get cheaper than those Black Friday'ess therefore, my current mailchannels plan may even satisfy my current volume (which is low) but worth checking other options
We are not into shared hosting but monitoring mailqeue with nagios or zabbix and limit amount of outgoing email per customer per hour is pretty standard and straight forward.
Just did setup some reportings. Let's see how it goes
You should also start to monitor the biggest spamlists for your ip address. either use mxtoolbox or write a simple script on your own to query the lists.
Already have daily monitoring with email and slack push to all major RBLs.
Mass mail problem is already solved now. Main problem is even tho you limit to like 100 per hour, those 100 mails can get you a or more notice. I don't think there's any solution to this now rather than mailchannels
My main reason to open this thread was to discus/see what other providers do
Mailcheap has also some kind of limiting, may be worth checking it out
Do you mean inbound spam or outbound spam?
My systems handle outbound only, I just use the standard cPanel (SpamAssassin, etc) to handle inbound.
Francisco
outgoing as he explained in his first post. to avoid getting blacklisted you also can rotate outgoing ip addresses and Scan your outgoing mails with spamassassin and so on
Frankly, I don't know how Francisco really manages to deal with the spam problem. Is he really able to catch most of the spam? I guess that, since a shared hosting user at buyvm gets a dedicated IPv4, there's not a single shared IPv4 that could be blacklisted. But still, Francisco seems brave to tackle this problem on his own.
Outbound spams. That kinda php mail wrapper of yours IIRC.
But since it also limits the account, I guess it'd work same as disabled mail.
@angstrom is right on point, there.
I am now thinking of this:
Exception list for user accounts.
Cron to disable outgoing features of account but enabling on the ones in exception list.
Seems legit way here. Some inconvenience to users but legit.
If I may ask, if your outbound spam filter designates an email as spam, is the email simply deleted without notification to the user who tried to send it?
IIRC, it wouldn't let php mail to pass without any notifications. I don't think it is even necessary to have noty.Thought it was asked to me
It's purely a whitelist for the account as a whole, it doesn't try to see if an email is spam or not.
99% of our shared users don't need sendmail or remote SMTP, so I block both and require people ticket for it. Some people get crabby about that or make threads on here/WHT complaining about it, but it's generally not bad.

So it's kinda what I mentioned above, right? WHM has api or command to suspend outgoing mails since 64 version which I guess should work fine as replacement.
I see, it's basically a trust-based system after a user requests and is granted the right to send email.
Yeah, perhaps you should do the same: a user is blacklisted by default but can be whitelisted upon request.
Been thinking this since morning. Implementation of this seems pretty easy too! There's just one problem that users don't know mostly about spam being sent.
Will try writing some reportings and auto suspension system something possibly in morning. Thanks fran for sharing and everyone else too
Hello,
We don't use
suspend_outgoing_emailfor that, but we do when a user has multiple SMTP accounts get compromised. It works very well.Remember, you can call it from CLI if you want to speed things up:
whmapi1 suspend_outgoing_email user=USERNAMEFrancisco
Yup, that. Wrote yesterday
I've wrote two script. One is to get top senders from mainlog. If emails sent is higher than xxxx, run that command for it.
If anyone's interested, here's link
lol shared hosting in 2018
go repent
nothing wrong using shared hosting for non-techie.
non-techies shouldn't be fiddling around with websites. much better to do apt-get install nginx php
It'll always be around
unfortunately
