The rpm allows me to link all usernames to all virtual domains, which is great. But one of my customers is still having trouble sending out mail through his own ISP (receiving is no problem). Can it be that they block all mail on port 25 which is not their own mail? Or is this a DNS related problem which I have to tackle in my SME?! Is it possible for him to use my SME as a smtp??
Any help would be greatly appreciated!!
cheers, Mark
