A client is trying to send a rather large email but it gets bounced back with the following message:
Hi. This is the qmail-send program at server2.hysir.net. I'm afraid I wasn't able to deliver your message to the following addresses. This is a permanent error; I've given up. Sorry it didn't work out. <email@example.com>: 188.8.131.52 failed after I sent the message. Remote host said: 552 5.3.4 Error: message file too big
I've checked and there is no limit on outgoing mail size on our end and this ip address i.e 184.108.40.206 is the ip for the receiving mail server, am I right to assume the mail server for laeknastodin.is is denying the mail due to its size rather than our smtp refusing to send?
