So, when we notice a sudden dip in mail volume compared to the same hour in previous dayswe analyze the mail logs and review recent changes to the mail server settings. First we find out from the mail logs when the spamming started, and then we check the web logs to find our all script activations at that time.

We look at the upload time, and code of these scripts to determine if they are spam scripts, and if yes, we delete them from the server. The mail server logs will show a single user repetitively logging in and sending hundreds of thousands of mails in a single batch.

When we see an abnormal spike in outgoing mails, we immediately locate the sender. Furthermore, we get in touch with the account owner, and help them reset their passwords for FTP, Control Panel and all other logins as the attacker is likely to have accessed them all.

So, we ask the customers to use a new PC to reset the password, re-install the Operating System eg. Windows 10 in the current PC, and to enable a firewall.

That is why, here at Bobcares, we make sure we setup preventive actions as a follow-up to spam mitigation. So, in the servers we manage we set a default limit of 50 mails per hour for each user, and increase the limit on a case-by-case basis. To counter that, we setup Malware scanners that is activated every time a new file is created.

This ensures that every spam script is weeded out before it can cause harm.

Trusted Helper. Re: Emails to twc. Community Manager.Written by Julia. Posted in Email Marketing. It often happens that legitimate emails are being blocked or moved to the Junk folder by ISPs. Whatever the cause of the email blocking is, you can take it under your control and adjust your email program to overcome the ISP email blocking challenges in your future campaigns.

After you understand why ISPs block some emails and how to avoid the problems, you will be able to improve your email deliverability and increase your email open rate. As you probably guess the main reason why the emails are filtered is spammy looking content.

You will absolutely recognize spam emails at first sight: unknown email address in the From field, misspelled Subject, Subject lines written in ALL CAPS, large and often bold font size, pure promotional and sales content. Furthermore, have you ever paid attention to the links you use in your emails? You may think why you should care about the links if they are from your own domain.

I thought the same until the recent time when I discovered that the links may be a cause of email blocking. I registered the glockeasymail. There was only an open source directory link exchange script installed. Some time ago I received an email from PayPal telling that glockeasymail. I addressed this issue immediately, removed a hacked directory link exchange script from the site and removed all the scripts uploaded by scammers.

It seemed the problem was solved. A few weeks ago I sent an email campaign to my customers. The email contained a link from the glockeasymail. The majority of emails were sent successfully. I found that a couple of dozens of emails were blocked by Barracuda and FortiGuard spam filters and returned.

I decided to send a short message to those customers asking them to provide me with a different email address. This made me think that the problem might be in the URL I included into my original message and, in particular, in the domain the URL was from. Keeping this in mind I replaced the original link with a redirect link from our main glocksoft. This time the emails passed through the filters and reached the recipients. So, if you find your emails blocked by the spam filters, it may be because of a domain name you use in the message content.

A quick solution is to use a redirect method like I did. Talking about links in the email body, not only the domain may be a cause of the email blocking or filtering.

Besides spammy looking email content, there are some other reasons for the ISPs email blocking or filtering such as too many spam complaints, too many invalid addresses on the list, and technical sending issues.

Many email marketers receive spam complaints. You should address this issue as soon as possible.
