jump to https://docs.python.org/3/library/imaplib.html#imap4-objects,

in the "See also" text, the url(https://www.washington.edu/imap/) of the University of Washington’s IMAP Information Center is not available.

hello,
I am new to python repo,
I would like to contribute here.

I checked the page to told and it is showing that https://www.washington.edu/imap/ is not found.
I tried to find the url to their documentation but I couldn't found one. can you please guide me here

maybe，you can try to contact the webmaster of the University of Washington to get the correct url

I contacted them I got to know that the project is discontinued since 2008 and the resources are no more maintained.
they have provided with an github repo and an archive file link 

This is the exact reply:
Unfortunately, both UW IMAP and Pine/Alpine development was discontinued back in 2008 and removed from University systems in 2018. A community copy still exists at https://github.com/uw-imap/imap but UW provides no support or resources for it anymore.  It looks like some of the information may still be available via the Wayback Machine https://web.archive.org/web/20080323102305/https://www.washington.edu/imap/  

Mark Crispin, the lead developer at UW, started a fork of it called Panda IMAP when he was laid off in 2008, but he has unfortunately passed away and that no longer seems to be maintained.

what would you like me to do next ?

Should I change the link to new one (not University of Washington’s IMAP Information Center) as it contains so much information about IMAP4.
I could not find any link from University of Washington, So I suggest changing the link all together. I have a link in mind
I can open a PR If you agree.

I made changes to rst file and added link that I got from university of Washington do check it. Let me know if any changes, you find it proper. I will submit my PR.    
changes in shown in image

The link provided gives UW IMAP Server Documentation not In general Documentation Of IMAP

As Documentaion of imaplib we should provide information of imap itself

Sorry my Bad your version is Good you can submit your PR,If any problem May I submit it please

It doesn't make sense to include the archive link, the documentation it refers to is available in the GitHub repository under docs/.

Then I shall remove the archive link

The build fails because of "Inline emphasis start-string without end-string." and bash script exists at code 2
can you please Help me.

This is what I get:
