Notify 1.4.2 always sends two emails #6

Closed jolichter closed 5 years ago

jolichter commented 5 years ago

Hi Bob, maybe it is a bug? Notify always sends two emails instead of one.

I use

Also tested this with a new local installation and get the same two emails. It can’t be the PHPMailer, because emails sends with FormIt only once?

PS: Sorry, I have started this issue in the modx forum, but I guess here it's better.

Here my Debug-Log:

Are you telling Notify to send a "test email" or sending bulk email with just one user?

My wild guess is that PhpMailer is not reporting success even though the email has been sent successfully so Notify retries sending the batch. It might work properly if the batch has more than one user.

It could also be an issue with using a localhost install since the sending domain is not a real domain.

I use Mailgun (free) and haven't ever seen this issue there.

jolichter commented 5 years ago

Hi, thanks for your statement. Just tested it with 3 user and sending as bulk email and each user has received 2 emails again. Tested on my localhost Linux computer and a real hosted domain. Strange! btw: I don't like Mailgun, especially because of the German DSGVO (privacy policy).

BobRay commented 5 years ago

I found an old thread on this at the MODX forums. Try this:

Edit the core/components/notify/processors/mgr/nfsendemail.class.php file and try changing line 503 from:

$maxAttempts = 3;

To

$maxAttempts = 1;

jolichter commented 5 years ago

Thanks! This is a good workaround for me.

Unfortunately, this error log remains: (ERROR @ /myserver..../modx/core/model/modx/mail/modphpmailer.class.php : 175) You must provide an email address to send to. I excluded this log error in modphpmailer.class.php and I'm aware that this is a bad solution.

BobRay commented 5 years ago

Do you have a &mailReplyTo value set in the properties?

jolichter commented 5 years ago

Oops, yes that value was missing! The error message "... email address to send to" is a little misleading. It should be better called "reply to"?

THANKS BOB!

BobRay commented 5 years ago

It should, but it's a generic message in PhpMailer that fires when address() (used for "TO", "Reply To", CC and BCC) is called with an empty email address.

FWIW, the missing reply-to might have been the cause of your double messages.

jolichter commented 5 years ago

Hi Bob, Yesterday I go online with Notify and noticed that the emails still send two times (no error log). However, this workaround from the old forum fix it: $maxAttempts = 1;

BobRay commented 5 years ago

Thanks. That fix will be in the next release.
