Git push error: ssh: Could not resolve hostname domain.com[:7555]: nodename nor servname provided, or not known

Question

I can't seem to use Git to push to the server. However, I can SSH to the box.
I can't figure out why:

$ cat .git/config   
[core]  
    repositoryformatversion = 0  
    filemode = true
    bare = false  
    logallrefupdates = true  
    ignorecase = true  
[remote "server_idm"]  
    url = ssh://[email protected][:7555]/home/username/repo_Project/  
    fetch = +refs/heads/*:refs/remotes/server_idm/*  

$ git push server_idm

ssh: Could not resolve hostname domain.com[:7555]: nodename nor servname provided, or not known fatal:  
The remote end hung up unexpectedly  

However, I can easily SSH to the box.
$ ssh -p 7555 [email protected]

Try removing the square brackets in the URL.
