Cannot use a number at the start of an email address
have been testing the Sun Java Messaging Server and discovered an interesting bug. It appears you cannot use numbers only as a prefix in an email address i.e. 61123456789@airscape.mobi. If you attempt to send to an address of this type you get the following error:
"SMTP Error: 5.5.1 Unknown or illegal alias".
This is not a problem in Outlook. If I prefix the email address with a single letter it works fine.
I am not sure whether this is a superficial problem in the SJCS email web client or deeper down. In either case it is a bug in SJCS that probably needs to be addressed.
The justification for this posting is we are using phone numbers as email address prefixes. We are developing email for the mobile phone and it would be one less thing to remember.
