12.0p Mail sending problem, perhaps mail header and content mixup (?)

[Blama]

Hi Isomorphic,

I have a super strange issue, where sending mails via your <mail> tags fails.

This is the exception stack trace (v12.0p_2020-03-11):

javax.mail.internet.AddressException: Illegal semicolon, not in group in string ``Christian <christian.lastname@company.de>'' at position 13

In the mail html template I have this line:

<td>$!esc.html($lead.STATUS_STATUSCOMMENT)</td>

The field STATUS_STATUSCOMMENT included user content, and the problem is with this:

Von: otherLN, otherGN <otherGN.otherLN@company.de>
Gesendet: Montag, 5. Juli 2021 19:15
An: Vertrieb <vertrieb@company.de>
Cc: Lastname, Christian <christian.lastname@company.de>
Betreff: WG: xxx

Hallo Frau xxx,
...
...

As you can see the text of the field is a copied mail in German. Instead of "TO:" it has "An". But "CC" is the same in German / English.

Is it somehow possible that because of the way you try to build the mail in TemplatedMailMessage.java:260 the content is somehow interpreted as header further down the line and this "CC: ..." is not valid? (";" in HTML-encoded content for "<" etc.).

When I add customSelectExpression="null" in the .ds.xml for the STATUS_STATUSCOMMENT-field, and by this remove the content from the mail, the mail sending succeeds.

Thank you & Best regards
Blama

[Isomorphic]

Interesting theory, but if true, it should be easy to isolate into a test case where there are not so many other possibilities for the failure. Can you do so?

[Blama]

Yes, will do so next week.

Best regards
Blama

Out of interest, what does TemplatedMailMessage.java:260 and surrounding code look like?

Hi Isomorphic,

I could reproduce in v12.0p_2021-03-31 BuiltInDS SuperDevMode.

Please edit the "information" field of Elephant in the GUI to the text of #1, then click the "Send mail" button.

Please, we need you to post your Animals.mailFetch() implementation in order to test your complete test case.

Isomorphic Software

[Blama]

Isomorphic,

it is just return request.execute().

package com.smartgwt.sample.server.listener;

import javax.servlet.http.HttpServletRequest;

import com.isomorphic.datasource.DSRequest;
import com.isomorphic.datasource.DSResponse;

public class Animals {

    public DSResponse mailFetch(DSRequest request, HttpServletRequest servletRequest) throws Exception {
        return request.execute();
    }
}

We couldn't reproduce the error with the latest build of 12.0p. Please, try with that.

Hi Isomorphic,

also happening with v12.0p_2021-07-06/PowerEdition Deployment for me:

Are you sure you changed the text for elephant?
This is what my screenshot looks like after clicking the button:

[Blama]

Hi Isomorphic,

could you reproduce this one?

Thank you & Best regards

[Isomorphic]

We have applied a fix for this issue which will be available as of tomorrow's builds (Aug 11).

Please, let us know if you see any other issues on this part.

Isomorphic Software

[Blama]

Hi Isomorphic,

I retested with v12.0p_2021-08-11 and it's working as expected.

Out of interest: What was the issue here?

Thank you & Best regards
Blama

[Isomorphic]

Similar to what you guessed: content was potentially interpreted as headers due to the use of parse().

[Blama]

Hi Isomorphic,

by chance I found the new method TemplatedMailMessage.getMessageParseMode() in 13.1d. MailMessageParseMode itself is already doc'd in 13.0p.

Out of interest: Am I right in thinking that this works similar in previous versions (12.0p, 12.1p), but wasn't configurable?

Best regards
Blama

[Isomorphic]

That's basically a backcompat API for people who may have depended on the previous behavior of parsing headers out of body content.
