I made a function in a python script that returns an ical file, but when I try to import it into busycal, it says "no events imported". I have checked and doublechecked, yet I can't find anything wrong with it. Here is a (short) example of such iCal file that doesn't work:

I discovered the cause of the problem; the DTSTART and DTEND dates had only 1 zero to represent seconds instead of the required 2.

I am using my own selfmade php calendar. Every time I update the calendar, an ics file is created and placed in the "ical" directory on my server under the name "24633.ics". I can import the file into my Google calendar, but it fails on other booking websites. The file complies with the ics standards. What went wrong? What are the requirements for the calendar or server to import the file from booking websites?

Then using phpmailer, I am attaching the file generated to an e-mail message and send it to the users who are participating on the event. Users who are using thunderbird (with Lightning extension - which is by default on) receive the e-mail message in the following format:
As you see in the picture the ics file is parsed and rendered in the table at the bottom of the e-mail. However the table header (the one marked in red) is not displaying correct information. Test user has not ever cofirmed his/her presence, and if he does, the ics file does not provide any info about it.
Am I formatting the ics file wrong?
Is it a known bug of thunderbird / Lightning ?

You should make the Content-Type of the ics attachment something like:
Content-Type: text/calendar; charset="utf-8"; method=REQUEST
The method option is the magic word. I'm not completely sure this works, but it is at least closer to the spec. I'm happy to update my answer if it doesn't work.
From my raw server logs, I found these:
52.42.136.103 02/Aug/2016:17:58:12 GET /administrator/
54.234.186.225 03/Aug/2016:16:48:55 GET /administrator/

52.40.119.32 08/Aug/2016:06:02:45 GET /administrator/
The ip's all belong to Amazon Technologies (and I don't have an /admin directory).
I'm used to seeing that kind of random probe thing (/wp-admin, /wp-blog/, /dir, ... ) from Russia and Vietnam and so on, and I've always assumed there was some nefarious motive behind it. Is there? Why would Amazon be doing that? Is Jeff Bezos out of control?
Amazon itself is not crawling your site but more likely to be some of their EC2 users (i.e. rented servers on the cloud). See below for email address to contact Amazon if you think their users are doing something illegal or abusive

I made a lot of research about this topic. I have an Apache James 2.3.2.1 Mail Server. I'm configuring it as a production server. I got it running, and stable, but implementing jDKIM have been troublesome. I found these links to get it right.
http://www.nailedtothex.org/roller/kyle/entry/configuring-james-to-sign-dkim
https://github.com/smoradi/config/blob/master/noften/apache-james.txt
Until now, I verified the public and private keys repetitively. Mailets libraries. Java code and configuration for the Mailet.
But I'm stuck.
While testing with www.appmaildev.com/en/domainkeys/, I finally solve some errors over the themes named above. But now It's just toying with me.
In the DKIM Test result it says that the expected body hash must be
Expected Body Hash:
: frcCV1k9oG9oKj3dpUqdJg1PxRT2RSN/XKdLCPjaYaY=
But in the Message Header says that the body hash is just that.
bh : frcCV1k9oG9oKj3dpUqdJg1PxRT2RSN/XKdLCPjaYaY=
And It's just the same so this test should be OK.
Maybe I'm missing something over de DNS or in the Mailet configuration, I just dont know i have been trying to approach in different ways but this is were I get every time.
As a note, before getting this point, every time I send a mail over Outlook or Homail, it was getting to the Junk immediately, now is kind of random almost every 3 or 5 sends. While Gmail since the SPF got them always in the Inbox. And The server does not have an PTR record properly configured in the DNS.
This is the Mail from appmaildev.
I change my domain name over example.com
And change the IPs to xxx.xxx.xxx.xxx
this test in particular was made over telnet using ehlo
I marked the puzzling part of code with ** **.

After more research and testing, I made it to work.
It seems that I had missing values in the DKIM-Signature.
This was my original tag in config.xml for Apache James in the DKIMSign mailet:
<signatureTemplate>v=1; s=selector; d=example.com;
h=from:to:received:received; a=rsa-sha256; bh=;
b=;</signatureTemplate>
I was missing the "c" and I made a change over the "h"
c=relaxed/relaxed;
h=Message-ID:Date:Subject:From:To:MIME-Version:Content-Type;
After the modification I got this:
<signatureTemplate>v=1; s=selector; d=example.com;
h=Message-ID:Date:Subject:From:To:MIME-Version:Content-Type;
a=rsa-sha256; bh=; b=;c=relaxed/relaxed;</signatureTemplate>
Another Detail, that I made several test about was the DNS Record. Mine was over Windows Server , so just for caution, I checked these details.
First , The escape char before the semicolon in the "k"
k=rsa\;
Second, That the "p" value, was the last value and that does not have a semicolon or escape char.
p=MIG...QAB
So that, after a host command I got something like
selector._domainkey.example.com descriptive text "k=rsa\;p=\010...QAB"
After those changes and checkings. It pass every test :)
Another link i found usefull for the configuration was this.

And when i import this file with google calendar import is successful but i don't have reminders so what i do wrong with VALARM and how can I fix this?
Your icalendar file does not validate, it is missing the UID at DTSTAMP properties. Try adding those properties and see if the alarms work.
