Frequently when sending mails, some of the addresses fail and messages like this appear in phplist.htm (the send report file)
Error sending message 31 (45/50) to ipg@xxx.uk (ipg@xxx.uk)
…
45 failed (will retry later)
As I send messages in batches of 50, the delivery gets clogged with those failed email addresses and it slows down dramatically, as phplist is trying to send to the same problematic addresses over and over again
is there any setting to tell phplist not to retry emails that have such permanent errors? Note this is not a bounce
