I am new to Vue and I am so far enjoying the Single File Components.

Prior to making what I really want to make, I figured I would try some small things to see if I grasp the concept.

So I set off to make a component for opening an XMLHttpRequest, with a progress bar.

I have followed this tutorial to configure DKIM and Postfix on Debian 7 wheezy. These instructions are pretty much a standard on the interwebz.

I am using Gmail to send and receive emails using my own domain. I followed this instructions to achieve that.

My problem

I can send and receive emails but I can't manage to pass the DKIM test (at least with Gmail). After searching and struggling for a while I have come to the conclusion that the reason of my woes is that my message is getting multiple DKIM signatures (see mail.log below). And this, according to the DKIM directives is enough for the DKIM to fail.

But after reading about on how to solve the multiple signatures problem I found that absolutely all of these solutions refer to having 'amavis' installed. Thing is...I don't have it installed!

In any case these solutions mention changing postfix configurations related to the milters in master.cnf and/or main.cfn. For example, adding this to the 'receive_override_options' (again, I don't have that variable since I don't have amavis installed) should solve the issue:

I'm new to Haskell and am finding it difficult to make sense of it. I'm trying to understand someone else's code by testing out a function but cannot figure out how to do this. The function is below:

Secondly I apologize if the answer to this post happened to be "obvious", but to make it simple I have absolutly no idea what I'm doing, this is the first time I try to do this.

I'm trying to send mails with PHP mail(), but it fails every time when I do it at home even though it works just fine at my school (I use PHP7 both at school and at home, so I'm guessing it comes from my server configuration at home).

I've tried many tutorials requesting to update this file and that other file, none of which seemed to have any positive impact on the result, so here's what I did so far:

I have installed postfix, but for some time having trouble with it.

I am able to connect to port 25 on local host, but when I telnet port 25 from an external machine, the connection appears to be made but then hungs up.

I get the response:

421 Cannot connect to SMTP server xx.xxx.xx.xxx (xx.xx.xx.xxx:25), connect error 10061 Connection closed by foreign host.

I have inet_interfaces set to all.

I am setting up squirrelmail to access it from anywhere from internet. I have installe postfix and dovecot on ubuntu 16.04. I am able to send mail to someone@gmail.com from me@mydomain.com with ms-outlook on my desktop. but when I try it from https://squirrelmail.mydomain.com I get

I am making a Javascript timed quiz with 10 questions to be answered in 60 seconds. It works fine if the contestant attempts the question in 50 to 60 seconds, but if he does it in a shorter time and restarts the quiz the timer runs at double the speed. Possibly the earlier timer isn't getting cleared. Here is the script:
