https://github.com/emersion/go-imap
If possible, provide a recipe for reproducing the error.
A complete runnable program is good.
A link on play.golang.org is best.
package main
import (
"bufio"
"fmt"
"log"
"os"
)
func main() {
}
What did you expect to see?
I expected the program to connect to the IMAP server.
What did you see instead?
