Yahoo is not fetching email/folder list anymore
Hi @emersion . Here is the sample code
package main
import (
"log"
"github.com/emersion/go-imap/client"
"github.com/emersion/go-imap"
)
func main() {
log.Println("Connecting to server...")
// Connect to server
c, err := client.DialTLS("imap.mail.yahoo.com:993", nil)
if err != nil {
log.Fatal(err)
}
log.Println("Connected")
// Don't forget to logout
defer c.Logout()
// Login
if err := c.Login("[email protected]", "app_password"); err != nil {
log.Fatal(err)
}
log.Println("Logged in")
// List mailboxes
mailboxes := make(chan *imap.MailboxInfo, 10)
done := make(chan error, 1)
go func () {
done <- c.List("", "*", mailboxes)
}()
log.Println("Mailboxes:")
for m := range mailboxes {
log.Println("* " + m.Name)
}
log.Println("hello...")
if err := <-done; err != nil {
log.Fatal("folder fetch error", err.Error())
}
log.Println("folder fetched...")
// Select INBOX
mbox, err := c.Select("INBOX", false)
if err != nil {
log.Fatal(err)
}
log.Println("Flags for INBOX:", mbox.Flags)
// Get the last 4 messages
from := uint32(1)
to := mbox.Messages
if mbox.Messages > 3 {
// We're using unsigned integers here, only substract if the result is > 0
from = mbox.Messages - 3
}
seqset := new(imap.SeqSet)
seqset.AddRange(from, to)
messages := make(chan *imap.Message, 10)
done = make(chan error, 1)
go func() {
done <- c.Fetch(seqset, []imap.FetchItem{imap.FetchEnvelope}, messages)
}()
log.Println("Last 4 messages:")
for msg := range messages {
log.Println("* " + msg.Envelope.Subject)
}
if err := <-done; err != nil {
log.Fatal(err)
}
log.Println("Done!")
}
I have added some logs to check if it was sending correct imap commands. Looks like it is.

Anybody can help me, please?.
Can you add
c.SetDebug(os.Stdout)
And copy-paste the output, removing any sensitive data?
Thanks for the quick reply. I have added the line you mentioned.

But the email fetching works perfectly with nodemailer. Thanks for your time again.
Maybe they use different arguments in the LIST command. Debug logs would tell.
It does not work with go version
go version go1.13.8 darwin/amd64
but works with
go version go1.12.17 darwin/amd64
Support for SSL version 3.0 (SSLv3) is now deprecated and will be removed in Go 1.14. Note that SSLv3 is the cryptographically broken protocol predating TLS.
SSLv3 was always disabled by default, other than in Go 1.12, when it was mistakenly enabled by default server-side. It is now again disabled by default. (SSLv3 was never supported client-side.)
Ed25519 certificates are now supported in TLS versions 1.2 and 1.3.
As announced in Go 1.12, Go 1.13 enables support for TLS 1.3 in the crypto/tls package by default. It can be disabled by adding the value tls13=0 to the GODEBUG environment variable. The opt-out will be removed in Go 1.14.
It does not work with go version
go version go1.13.8 darwin/amd64
but works with
go version go1.12.17 darwin/amd64
@emersion Do you know if it works on any version older than 1.12? See my comment above with what changed between the two versions. There's a clue in there somewhere.
