outbound email blocked by router
When I try to send outbound email I get this message an error message with these infos on three lines:
SMTP error
4.2.0 followed with a code mixed with letters and numbers that is changing at each request followed by server temporarily unavailable
AUP#EML-006.
So I may receive my emails but cannot send any. I called my ISP and after diagnostic, it is shown that it is my router that blocks them. Wheen I either bypass it or put my old router it works. I cannot find any settings to arrange this. Also, I have tried te reset my router to default settings and it is still blocks them.
Any ideas?
