If someone receives msg from your mail id does not concludes that your account was compromised
First you should check wheter your account was accessed. You mentioned mail was received by your colleague around 4 am
in your yahoo mail go to account info > view your recent login activity
Check whether account was accessed around that time
If you normally log in by using same system or place then ip range will be very very similar if its some other then your account was prolly compromised
If the person who received the mail still has it then ask that person for headers (enable full header option to view) This function is available in almost every such service provider
It is possible to send mail by using someone else id and in that case non pro would use help of third party and genrally the third party will include all the relevant info you need
Example of info in header (from my mail) I will falsify some info in header for obvious reasons .Its just an simple overview
IPs wont be exact unless static and always used the same static ip . Which genrally does not happens but to solve it out agencies contact the gate from where the info is coming and a lots of procedures
Compare the header info b/w 2 and see the difference
You should be able to identify whether this particular technique was used or not

in case of spam mails they either block msg originating from those ips range of ips (even continent wise)
Like Asia is not much welcomed in some countries because of very high spam rate (mainly 'cause of CHINDIA)
or send them to spam mail
Sending mail using third party (used authentic one and not the naughty ones , you know what I mean)

X-Apparently-To: PERSONS MAIL ID via 106.10.145.239 (IP address of the Third party the site I used)
Fri, 29 Jun 2012 06:02:02 +0000
Earlier the IP was 106.10.145.238 but now its 106.10.145.239
Different IP used but from the same entity . An entity may own series of Ip address
(In both the examples IPV4 been used because many entities use IPV4 'cause of many benefit even after paying
abnormally high price for it as compared to IPv6 and even before IPv6 (google a live example it bought many
IPv4 at huge cost)
Lets check the address
https://www.ip-adress.com/whois/yahoo.com
Return-Path: <ID you want to show as YOURS>
Received-SPF: none (domain of yahoo.in does not designate permitted sender hosts)

Why the new IP?
Lets check this ip first

Yahoo received from speedbit 212.143.22.13
Speedbit received from FFWC1
But why ?
Because its not necessary that the server which is receiving the info should send the info
Lets check
https://website.informer.com/81.218.19.11
It says the msg of person sending msg was received by 81.218.19.11
Msg was sent from different gate 212.143.22.13 to yahoo
Msg recevied at 106.10.145.239
Thats what happens when we recieve msg indirectly . Bah its becomes lenghty when you use
CC and BCC and forwards in your mail :(

It is also possible to falsify the info in headers but that can also be known and a few other ways to MAJEY LENA PRAKRIYA and we counter it and cycle continues
If you want then you can complain to yahoo and if its found that account was compromised you may file complain
