fixed : block sender in Gmail

Question :

I would like to never receive another eMail again from some people that keep sending me spam-eMail. How can I block the senders in my Gmail ?

Answer :

In Gmail, you can’t block a sender.

However : using a filtering action and ordering filtered eMails to be trashed will have about the same effect as blocking the sender.

Here’s how to do that :

– in your webbrowser (Safari), go to

– login using your Gmail-address and your Gmail-password

– when your online Gmail eMail-client opens, go to the list on the left and select the mailbox where the eMail who’s sender you want to block is located ; this can be your “Inbox”, but it can also be listed under “More…” and then inside your “Spam” or “Trash” mailbox ; if you can’t find the eMail you’re looking for, try “All Mail”

– select the eMail message itself from the list in the middle of the screen

– when the eMail message opens, click on the ‘downward facing triangle’-button (the one that’s next to the date, there star and the reply-arrow), and select “Filter messages like this”

– in the window that opens, the sender you want to block will already be pre-filled in the “From”-field and all other fields will be empty ; leave everything as-is, just click on “Create filter with this search” (in blue, bottom-left)

– in the next window, put a check-mark at “Delete it”, and click on the blue “Create filter”-button

…that’s it !

TIP 1 : If you have any other senders you would like to block, just repeat the above steps for each sender.

TIP 2 : if you want to block multiple senders using just one filter, put all eMail addresses in the “From”-field and separate them by a SPACE, a |-sign (vertical separator) and another SPACE

TIP 3 : in the event that you change your mind and want to un-block a sender you’ve previously blocked, just login to your online Gmail account again and click on the sprocket (a.k.a. ‘gear’) icon ; in the pop-up menu that appears, select “Settings”, then the “Filters”-tab and click “Edit” to adjust the filter or “Delete” to completely get rid off the filter

Note : any new filter will only be filtering new eMails, not the eMails that have already entered your mailboxes, so all existing mails by the blocked sender have to be manually deleted also.

Any new eMail by these senders will now be deleted when it arrives, so you won’t see it in your online Gmail mailboxes, nor in Apple on your Mac, any longer.

fixed : block senders of incoming spam eMails

Question :

I keep getting a lot of spam-eMail lately, most of the time from the same eMail-address.

Is there anything I can do to stop this ?


Answer :

The extend to which you can fix this, depends on the options given by your eMail-host, but bottom line it all comes down to configuring a filter.

– open Safari (or any other browser of your choice)

– go to your eMail-host’s internet page and login using your name/eMail and password

– go to the Preferences-menu and configure a filter there that checks all incoming eMails on the criteria you configure (e.g. the sender’s eMail-address) and sends all filtered-out eMails to the trash straight away (there might be a “block sender” option, but that’s not always the case)

If you manage to set a filter as outlined above, you will not get those annoying eMails on your Mac, nor on your iPad, neither on your iPhone.

Just make sure your filter doesn’t filter too broadly, as that would even ‘desired’ eMails will get placed in the trash without ever getting into your mailbox…

If it’s not possible to set the filter in your eMail-host’s server, you will have to set a filter on any eMail-app you use on every device (so on your Mac, your iPad, your iPhone, etc.).

Setting an eMail-filter on your Mac should be done like this :

– open Apple and select the spam eMail in your inbox

– open Mail Preferences, click on the tab “Rules”, and click “New Rule”

– that will set a new filtering-rule, which has the spammer’s eMail address already in it

– additionally configure the action that all eMail of that sender should go straight to the trash [you can include multiple spammers or senders directly or at a later time, and sometimes it is even more effective to filter based on a specific (partial) sentence from the ‘Subject Line’ or ‘Body Text’]

If you think configuring filters is too complicated, you can also decide to keep on tagging unwanted (spam) eMails as ‘Junk’. Since the Junk-mailfilter teaches itself progressively, in due time all similar eMails will be automatically filtered out and placed in the ‘Junk’-mailbox.

Good Luck !

fixed : how to delete undeletable files

Question :

I have recently cleaned up my Mac by putting a lot of old and unused files into the Trash (after backing them up to an external hard drive). But now, when I try to empty the Trash, some files remain, they seem undeletable… I even get a warning I can’t delete them… even a Forced Empty-ing of the Trash doesn’t work… but I’m completely sure I want to get rid of these files…

Isn’t there any way to delete them ?

Answer :

Yes – there is.

These ‘undeletable’ files are so-called “system immutable”, which basically means they cannot be changed or deleted even by the Root (super user) in the Terminal. Even switching to “Single User” mode and attempting to remove them won’t work.

Here’s what to do :

– restart your Mac in “Safe Boot” mode (press the SHIFT-key during startup ; as soon as you notice it takes a lot longer to boot than usual, you can take your finger of the keyboard, but even then it may take some time for you Mac to completely startup, so be patient…)

– now, log in as an administrator (i.e. using the/an account that has Administrator-rights)

– then, empty the Trash…

…that’s it. Done !
