Since I installed Exim, there is a server (a distributor of computer related material where I often buy and that regularly sends me a newsletter) that can't send me mail any more. Checking my logs I always find this two lines regarding it:
2003-03-23 10:46:27 rejected EHLO from [213.26.70.21]: syntactically invalid argument(s): atv_ser03.intra.attiva.com
2003-03-23 10:46:27 rejected HELO from [213.26.70.21]: syntactically invalid argument(s): atv_ser03.intra.attiva.com
Where is the mistake? is this a specific problem in my configuration or something not RFC-compliant in their set up? This is the only server giving me this error. I do not have restrictions other than the default ones in my configuration of ACLs, deny senders and system-filter.
The only thingh I know is that it should be a Microsoft server (please do not reply that I should not be surprised.... :))))
