I have koha 4.18 version and trying to find a fix for Mailing through Koha I want the patron to email his cart to any Mail id he prefers. So i am tring to test this feature and while doing that, it gives me an error as "There is an error sending the cart" after clicking Send. When i checked the Opac-error.log file, this is the error i get. opac-sendbasket.pl: Error sending mail: Bad recipient <mail id of user>: 550 5.7.1 Unable to relay, referer: opac-sendbasket.pl: No valid recipient opac-sendbasket.pl: at /usr/share/koha/opac/cgi-bin/opac/opac-sendbasket.pl line 188 I configured Post fix with gmail as smtp to send and receive mails. It works fine if i echo a test mail and it reaches the recipient id. -- View this message in context: http://koha.1045719.n5.nabble.com/Koha-emailing-not-working-tp5836791.html Sent from the Koha-general mailing list archive at Nabble.com.
