phpList 3.3.1 only sending part of emails of the recipients

[sostberg]

Hey guys,
we encounter a strange problem with phpList 3.3.1: It doesn’t send all emails, but only parts of the recipients. It’s always a different amount of emails, that isn’t sent, in total numbers and percent of the entire list.
One list was 10,692, and 2,291 were not sent, and in another list there were 4,499, and 128 were not sent. The messages remain in the queue of unsent messages, and if we try to send the remaining, it seems to work, but actually does nothing.
It’s not a problem with the blacklisted recipients, as they rare already taken out.

I would be happy for any advice!

Thanks!

The only time I have had these kind of issues is when an email address had an unusual, unallowed character in it (in my case, these characters were not displayed, and ‘unprintable’). The system would hang on that email address, and would stop sending.

So you might want to export the list of unsent email addresses, and using a program like ‘vi’, edit the file, and look for unexpected characters.

Once I deleted the offending email address(es), everything worked as expected.

I already found an answer in another thread. I had a wrong configuration in my config.
But I will check this as well. I thought, email addresses with wrong characters were ignored?

Thanks!
