Hello,

I've got a report that an AOL Webmail user is getting the following bounce when replying to a message from our system:

   ----- The following addresses had permanent fatal errors -----
<Jdoeclarku.edu <mailto:Jdoe%40clarku.edu> >
<Another.Dudealumni.clarku.edu <mailto:Another.Dude%40alumni.clarku.edu> >

I was thinking it's the "%40" in the addresss, so I tried to simulate
it. I don't get the same 550 error. I'd like to make sure I'm correct
when I tell the user that AOL Webmail sucks and to use something else,
or else fix whatever is wrong with our system so that they don't get
bounces like this.

telnet hector.clarku.edu 25

Authorized Use only.
helo clarku.edu

250 Ok
rcpt to: <abennettclarku.edu <malto:abennett%40clarku.edu> >

rcpt to: abennettclarku.edu <mailto:abennett%40clarku.edu>
555 Unsupported option: <mailto:abennett%40clarku.edu>

Any ideas?
