I'm at my wits end
to solve a problem which has coincided with the release of Imail 8.02 and/or the
Sobig.F virus, but it may just be a coincidence. Several of my users' messages
and replies to an armful of recipients are bouncing with varying causes, usually
this:
"Unknown host:
<email_address>"
or
this:
"undeliverable to:
<email_address>"
or
this:
"Unknown user:
<email_address>"
And one or two with
this:
"This address no
longer accepts mail."
Whether by reply, or
a new message, from Outlook, or from Webmail.
A check with the
companies and individuls involved reveals that the recipients are having no
problems receiving messages from anyone else. Ipswitch support claims no
responsibility or knowledge of the cause except to say that it is the other
guy's server rejecting it. INTERESTING NOTE: I've had some success sending
messages to the problem addresses in this form: [EMAIL PROTECTED] whereas
normally it would just be [EMAIL PROTECTED]. Sound like DNS? We
don't have an in-house DNS server, but use our ISPs. This problem has just added
a couple new hostnames, all of which are business hostnames.
Any help would be
greatly appreciated.
