Hello List Happy New Year!
I seem to observe, that more servers have started rejecting email because of 'helo / hostname' mismatch. If for example, you run a mailman installation with virtual domains enabled and use SSL for the Web-Management part, you have one ip address per domain. sendmail or whatever MTA is used, will probably listen to all ip addresses and pick the one belonging to the domain for email sending, but still the hostname used in the EHLO is the one of the physical machine and not the virtual domain. I did a quick check of the SMTP RFCs, I could not find anything that requires the EHLO domainnamen to match the connecting IP address. So what is your opinion, is it legit to reject email because the ehlo domain does not match the connection ip's PTR record?
