Email sending failed (drop) if there is a "," in the mail to name

[sanaulla123]

Issue Summary

If the mail to name contains ",", The mail gets dropped and the email becomes the text before ",".

Sample code:

Email from = new Email("[email protected]", "From");
Content content = new Content("text/html", "Body");

Email to = new Email("[email protected]", "First Name, Last Name");
Mail mail = new Mail(from, "Subject", to, content);

TrackingSettings trackingSetting = new TrackingSettings();

ClickTrackingSetting clickTrackingSetting = new ClickTrackingSetting();
clickTrackingSetting.setEnable(true);
trackingSetting.setClickTrackingSetting(clickTrackingSetting);

OpenTrackingSetting openTrackingSetting = new OpenTrackingSetting();
openTrackingSetting.setEnable(true);
trackingSetting.setOpenTrackingSetting(openTrackingSetting);

mail.setTrackingSettings(trackingSetting);
mail.categories = Arrays.asList("category");

Request request = new Request();
request.method = Method.POST;
request.endpoint = "mail/send";
request.body = mail.build();
System.out.println(request.body);

Steps to Reproduce

1. Create a Request Object using sample code
2. Invoke the API using: Response response = sendGrid.api(request);
3. The response is successful. But the mail eventually goes into drop status.

Below is the status of the email sent with the Mail to name given above.

Hello @sanaulla123,

This is a known issue and is in our backlog for a fix. Unfortunately, I don't have a timeline for the fix. However, here is a workaround: sendgrid/sendgrid-python#291 (comment)

With Best Regards,

Elmer

Any update on this? This is very surprising to see this kind of issues remaining not fixed for such long time. Thanks.

Good news @sanaulla123 and @idntfy! This is issue is now resolved. Thank you for your patience :)

Still experiencing, I can provide SMTP-ID and MSGID if it's fine from privacy perspective (it doesn't look they can expose something, but I don't want to do this without your confirmation).

Please reopen.

My apologies, I was thinking of this issue: sendgrid/sendgrid-python#302

I have added your vote to this issue. Getting this fixed is a matter of priority. More +1s on this issue will help it rise in the backlog. Thanks!

For Java, for ourselves, applied the following workaround, which escapes it when needed:

import javax.mail.internet.HeaderTokenizer;
import javax.mail.internet.MimeUtility;

final String to = MimeUtility.quote("First Name, Last Name", HeaderTokenizer.RFC822);

(using javax.mail:mail:1.4.7)

That's cool @idntfy! May we please offer you some swag for providing that workaround?
