Author Topic: a few emails failing validation (Read 1671 times)

We have a problem with a few emails failing validation. The emails are valid and have been tested. There are thousands of emails being sent successfully. The failure is instantaneous once the bulk mail cron job runs, so these are not making it out of civi.

When viewing the bounce report, each emails fail because of the following reasons...

Bounce Type: Invalid
Bounce Reason: Validation failed for:

Any ideas?

You will need to access the bounce emails to be able to know more about it. (works in imap, you'll find it in the processed folder, I think it would be destroyed if POP)

Incidentally, it's been discussed to add the bounce emails directly in the activity of the contact, to make it easier to see things like that directly from civicrm. Would you want to sponsor it ?

Hi Xavier,
The problem is the bounce is not occuring from a bounce message.

The bounce is occuring within Civi - the no message is ever sent for delivery.

I know this because we setup a bulk email to some of the effected addresses. The mailing completed. All addresses were bounced (this is after we took them off "on hold"), but there is no record in the maillog indicating that a message was generated for those addresses.

If seems like an issue with RFC validation but the emails are completely valid and can be sent to from multiple providers. (google apps etc.)

what could be causing these few emails to be invalid.

Could they be in some kind of unsubscribe state?

Thanks

and to be clear... the user has not opted out of bulk mailing and the administrative hold is removed prior to send a bulk email.

Thanks

that error message is coming via this issue:

http://issues.civicrm.org/jira/browse/CRM-6410

(it was introduced in 3.2.beta3)

looking at the code: CRM/Mailing/BAO/Mailing.php, line 383 the bounce is most likely set there. so does the same email address bounce every time? if so, can you instrument the code and get more details

ping us on irc and we can assist

Hi Lobo

Look like the issue is within packages/Mail/RFC822.php (this is the only file that contains the specific text)
starting at line 501...

Code: [Select]

        // ... or any other format valid by RFC 822.
        for ($i = 0; $i < count($addresses); $i++) {
            if (!$this->validateMailbox($addresses[$i])) {
                if (empty($this->error)) {
                    $this->error = 'Validation failed for: ' . $addresses[$i];
                }
                return false;
            }
        }

Is appears that the error should include the address that failed. However in our case it does not.

Is it possible there could be a mis match between the master mailing list and the address validation list?
(I haven't had the time to trace through the code further)

Thanks,
Dave

dave:

i did not find that message in my initial grep

so good find

the same string is also present in the table: civicrm_mailing_bounce_pattern, so i'm not sure which one triggers it. if it happens repeatedly on the same email address should be fairly easy to figure out whats happening and why

We are still experiencing this problem with valid emails failing the check in RFC822.php.

At this point I want to by pass this function completely to restore user confidence in the system. Better to try and send to a few bad emails that continually flag good emails as bad.

I'm planning to just comment out the following block starting at line 503

Code: [Select]

            if (!$this->validateMailbox($addresses[$i])) {
                if (empty($this->error)) {
                    $this->error = 'Validation failed for: ' . $addresses[$i];
                }
                return false;
            }

Since it appears to be validateMailbox that is generating the invalid result.

Anyone see any issues with this approach. Were planning to upgrade in the near future but this issue has been going on for months with no resolution.

I have no confidence that the upgrade will resolve the problem.

Was this really the bounce msg ? It would send indicate that the email was empty, and the problem elsewhere (or that validateMailbox empties it)

$this->error = 'Validation failed for: ' . $addresses[$i];

I am not sure what is the benefit of this test as the email addresses are supposed to be correct because tested at the import/data entry.

Might want to simply replace that line and return an error only if there is a non empty this->error

Hi,

One thing that can cause this problem (up to version 3.3.5): commas in contact names: see http://issues.civicrm.org/jira/browse/CRM-7818
