Francesco, using nslookup or dig, how can I simulate a name resolution using 
this kind of dns name?

I´ve tried:
nslookup -type=MX university.ac.uk? MY-DNS-SERVER
and
dig university.ac.uk?

without success.

ps: Even nslookup -type=MX university.ac.uk MY-DNS-SERVER can´t find the 
correct address.

Yes, you can use a fake email b/c the trailing ? will screw things up 
anyway.

In fact it is not a correct address. IMHO, the bug is in the syntax 
check, not in name resolution and the suggestion is, XMail should detect 
this as a syntax error without even trying DNS resolution.


Well, I realize this makes two posts after my supposedly last one :-)

I suspect that university.ac.uk is not an existing 
domain name. Try with kent.ac.uk or warwick.ac.uk.

Hi all,

I don't think that XMail is still being developed and maintained.

But, just in case: a user of mine sent an email to 
first.l...@university.ac.uk? (note the trailing question mark).


XMail tried to deliver and failed for the following reason:

ErrCode  = -109
SMTP-Error = Unable to get UDP DNS response

Since I don't think the address should have passed the syntax check, I 
googled a bit and found that the address is RFC5322 compliant 
(http://tools.ietf.org/html/rfc5322#section-3.4.1) but contains domain 
characters that are not allowed by DNS. Section 3.4.1 says that


  Note: A liberal syntax for the domain portion of addr-spec is
  given here.  However, the domain portion contains addressing
  information specified by and used in other protocols (e.g.,
  [RFC1034], [RFC1035], [RFC1123], [RFC5321]).  It is therefore
  incumbent upon implementations to conform to the syntax of
  addresses for the context in which they are used.

So, I think in general XMail should not accept such addresses (and, more 
generally, the reference for syntax check should be RFC5321 more than 
RFC5322).


Final note: this may be my last message on the list; my server will 
close in a few days, and that will be the end of my (very good) 
experience with XMail. I leave the suggestion to anybody willing to keep 
XMail alive.


Ciao, Francesco
