Apologies, I misread your question. 

According to the imaplib docs, you can subclass IMAP4 and override 
`IMAP4.open` to create the socket and bind it to the desired interface.
You could also connect using IMAP4 and then close/reopen the socket
inside the IMAP4 connection object. 


I hope that is more help,
Ramit
