Sending problems, Sending from outlook 2007 sometimes does not work.
two email samples, I am not giving the actual addresses
1. email@example.com sends from outlook ok every time received ok
2. firstname.lastname@example.org sends ok from plusnet web mail but not from outlook. Did until recently and did once or twice since but no more. Messages not received
No send error messages, they seem to have been sent but disappear.
Send via gmail both ok , the are received every time
Outlook settings incoming 110 out 587 no SSL (995 in does not seem to work)
I cannot see what is happening here any ideas?
My problem is that I dont know if this happening to other emails I think I have sent
