Nim smtp library

[Cnerd]

Hello, I have been using the smtp library lately and i noticed that it does not 
natively support html emails. So i did so research myself and in short i ended 
up adding some headers to the smtp request. The html mail gets sent but some 
html tags are not rendered like img, svg and a tags, so does anyone have a work 
around on how to send html mail that will in fact render appropriately using 
the nim smtp library. This is the code
    
    
    proc sendRecoveryMail*(username, domain: string) : Future[bool] {.async.} =
      
      let logger = newConsoleLogger()
      logger.log(lvlInfo, "Sending password reset link as requested by user 
$1".format([username]))
      try:
        
        let
          userinfo = db.getRow(sql"SELECT email, userid FROM user WHERE 
username = ? OR email = ?;", username, username)
          sitemailinfo = db.getRow(sql"SELECT mailaddress, mailusername, 
mailpassword FROM site WHERE id = 1;")
        
        if sitemailinfo[0].isEmptyOrWhitespace or 
sitemailinfo[1].isEmptyOrWhitespace or sitemailinfo[2].isEmptyOrWhitespace:
          
          logger.log(lvlInfo, "Some mail info are unset")
          return false
        
        randomize()
        
        var mailhtml = mailhtml(username, $(parseUri(domain) / "resetpassword" 
/ $((username & $epochTime() & $rand(9999)).toMD5) / userinfo[1]))
        let
          mail = createMessage(
            "PassWord Recovery Mail Movestuff",
            mailhtml,
            @[userinfo[0]],
            @[sitemailinfo[0]],
            otherHeaders = @[
              ("MIME-Version", "1.0"),
              ("Content-Type", "text/html; charset=\"utf-8\""),
              ("Content-Transfer-Encoding", "quoted-printable")
              ])
          smtpConn = newAsyncSmtp(useSsl = true, debug=true)
        
        await smtpConn.connect("smtp.gmail.com", Port 465)
        await smtpConn.auth(sitemailinfo[1], sitemailinfo[2])
        await smtpConn.sendmail(sitemailinfo[0], @[userinfo[0]], $mail)
        await smtpConn.close()
        
        logger.log(lvlInfo, "Password reset mail sent to 
$1".format([userinfo[0]]))
        return true
      except:
        
        logger.log(lvlError, "Failed to send reset mail")
        return false
    
    
    Run
