It may just be a glitch, but keep an eye on it and let us know if you see it again. I can always raise a fault ticket for further investigation if it persists.

Every couple of months I send out a pdf to 4 'groups' of people (a society newsletter) through Windows Live Mail. There are no more than 24 in each 'group'. I've never had this problem before and I've been doing this regularly for about 4 years now but as I said the problem seems to not be there now. I have had problems with emails bouncing back as undeliverable from members with Yahoo and BT email accounts in the past though.

Not even a couple of mails but to large numbers of users? I only ask because that error code is normally related to email addresses being unknown or incorrect in relatively large numbers. By that I mean say you sent 1 mail to a group containing 50 recipients and our system identified 10 to be unknown, incorrect etc.

The problem seems to have gone away now. But to your question the answer is No. Only a few. Certainly less than 10.

Hi TeeBeeUK, had you sent a lot of mails the day before within the same 24 hour period?

Hi @TeeBeeUK

 

One reason could be that you're using port 25.

 

Try:

Outgoing Port: 587
Outgoing Security: STARTTLS
Outgoing Authentication: Yes
