Apple Event: May 7th at 7 am PT

Looks like no one’s replied in a while. To start the conversation again, simply ask a new question.

My account is sending spam and I can't stop it!

For almost two months now my account has been sending out hundreds of spam mails to known contacts and also unknown email addresses.


I contacted my domain name provider (nominalia.es) and they advised me to do a few things:

1 Change my email password, as well as the outgoing smtp password (Done. Twice.)

2 Install an antivirus. (I have Avast Mac Security. No viruses or other problems found),

3 Remove my email address from my website. (Done).


Despite having followed all their advice the problem continues as before.


This is so annoying as I am a business user and I'm spamming all my clients as well as friends and family. I need to make this stop. I have thought about abandoning my domain name and starting afresh with a new one, but as a long established business I really don't want to change my web address and email address unless absolutely necessary.


Any help would be much appreciated.



(I wanted to post this in a Mail community, but can't find one. Please move my message if there is a better location for it).

MacBook Pro, OS X El Capitan (10.11.3)

Before you loose all your clients...


I'd buy an external harddrive. Install a fresh copy of os x on it. You should be able to access all your data from the old drive.

(2) FireWire 800/400 Ports (Up to 100MB/s / 50MB/s)

(1) USB 3.0 Port (Up to 500MB/s / 60MB/s)

(1) eSATA Port (Up to 300MB/s)

Has a combo firewire 800/400 port. Not sure what this is. Looks like you will need 400 cable.

Probably best to get a new email address & tell clients to block all email from old.


A scary thought is that someone could have stolen your email list and be sending from another machine. Is easy to spoof email addresses in a spamming emailer. You could get one of these spammed emails and computer tranmission path of legit and spammed email.


Good luck😀.

Perhaps someother app is sending.


I recommend that you get a littlesnitch. littlesnitch will track your Web traffic and tell you which applications are sending data from your computer. Be sure to run it awhile because it will trigger a number of alerts. In trail mode, it will run for three hours per boot for a about a month.

This has nothing to do with your computer. There is no known Mac malware that sends spam.


The spammer has hacked your e-mail account. The solution is to change your password immediately.


Unfortunately, changing your password may not always be adequate. Some mail servers provide features that allow a hacker to leave themselves a back door, so they can get back in even after you change the password. One prominent example is GMail's e-mail delegation that can allow a hacker to "read, send and delete messages on your behalf."

Be sure to check the settings for your mail server and ensure that a stranger has not been given access. You may need your mail service provider's assistance with this.


In addition, hackers have been known to configure vacation messages or rules to send automatic spam responses to everyone who sends you e-mail. This problem will persist even after you have changed your password and closed any back doors that they might have left open. Be sure to check any of the settings on your e-mail server related to any kind of auto-replies or rules, such as vacation messages.


In addition to changing your e-mail password, see if your e-mail provider has any form of two-factor authentication to ensure that a hacker who manages to get your password still can't gain access to your account.


The only other likely possibility, if the problem continues after all this has been done, is that your e-mail provider's servers have a vulnerability that is allowing a hacker to send spam as a particular user without actually needing to log in as that user. Only your e-mail provider can say whether this might be the case.
