    Yes, we did check with Radiant.net and they have received nothing reporting any abuse from us. We also thought it might be an invalid error message but the recipient does receive Email from our personal mail accounts, blackberry or webmail as usual. It only seems to be an issue when sending from our work mail server. It has been driving us crazy! Thanks for your swift response though.

    We have had an ongoing problem for several months of our mail getting returned with an error message when only sending to certain Email addresses. The error reports: There was a SMTP communication problem with the recipient's email server. Please contact your system administrator. <technicpos.com #5.5.0 smtp;553 66.163.1.245 mail rejected due to excessive spam (Spamcop, SORBS)> We have verified with almost every Blacklist that we ARE NOT LISTED in any database under our IP address or our Domain technicpos.com. It also only seems to occur when sending to certain email addresses with domains at aol.com, yahoo.com, *.us etc. We are completely baffled by this and are in need of resolving this as soon as possible. We have researched all of the known blacklists with our mail servers IP address of 66.163.1.245 and searching to see if our domain technicpos.com is listed either. All searches we perform come up clean and report that the IP address and domain are not listed in any database. Somebody Please Help!
