RFC 1035 The labels must follow the rules for ARPANET host names. They must start with a letter, end with a letter or digit, and have as interior characters only letters, digits, and hyphen. There are also some restrictions on the length. Labels must be 63 characters or less. //RFC 1035 I've also noticed 1and1.com doesn't fit this bill either. Most programs should be able to handle labels starting with digits, however since it is contrary to an active RFC which we as internet users are meant to be using as a standard, it is obviously not best practice. Just another example of the rules slipping so much that it's hard to tell the good from the bad these days. -- The Exim Manual http://www.exim.org/docs.html http://www.exim.org/exim-html-current/doc/html/spec_html/index.html -- ## List details at http://www.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://www.exim.org/eximwiki/
