[somber heron]

suspend fun sendPasswordRecoveryEmail(userEmail: String,context: Context) {
        val account = Account(client)

        try {
            account.createRecovery(
                email = userEmail,
                url = "https://Showgo.in/reset-password"
            )

            withContext(Dispatchers.Main) {
                Toast.makeText(
                    context,
                    "Reset email sent successfully!",
                    Toast.LENGTH_LONG
                ).show()
            }
        } catch (e: AppwriteException) {
            withContext(Dispatchers.Main) {
                Log.e("AppwriteRepository", "Error sending reset email: ${e.message}")
                Toast.makeText(
                    context,
                    "Failed to send reset email: ${e.message}",
                    Toast.LENGTH_LONG
                ).show()
            }
        }
    }

i am sending the verification mail through this code, though i am sure it has no error, but just in case...

when i am disabling the Custom SMTP the mails are received instantly

but with custom SMTP, nopee..
