NPrinting:error while sending a message(Unable to relay)
Hi gurus,
I'm using Nprinting designer version15.3. and Nprinting server version 16.0.
Everything was running perfectly till several days ago. Nprinting started failing to distribute emails. The error I got is
" Error while sending a message (Unable to relay)". It is quite wearied, since it just happened like a click. I suspect it may be regarding to SMTP settings. But I sent test E_Email from Nprinting e-mail settings and it worked.
