Email address domain being used by others.

[Alan]

In my small business we have an email address that looks like
"(e-mail address removed)"
The 'ab' before the @ symbol can be any letter or character but as long as
the email domain remains as 'mydomain.co.uk' then the email will always come
to our email inbox.
Lately we are receiving lots and lots, 70+ per day undeliverable bounces
from email addresses that we do not do business with and nor have we sent
them emails but it would appear that they have received a mail from
(e-mail address removed) (were xxxx are random letters).
I have spoken to our ISP and they have advised me that because we have POP3
and SMTP send/receive account with them that this problem cannot be stopped.

Anyone else know how to avoid this problem - ideally I only want genuine
emails to get through to us.

Spammers and viruses spoof the sender all the time - you can't do anything
about this.

Because you have a "blind forward" or "wildcard", this is always going to be
a problem. You're much better off defining specific mailboxes & SMTP
addresses and getting rid of the wildcard.

Thanks for the reply.
How do I define specific mailboxes & SMTP addresses and get rid of the
wildcard. This seems to be the way I want my email to work as I only want
emails to my nominated (e-mail address removed) address.
Your help appreciated.

I would guess that the mailboxes you have set up on your ISPs mail server
include a setting that sends all mail not addressed to a specific mail
address, but sent to the domain, to your master mailbox. You might be able
to change that setting to forward all that mail to a throw-away mail
account with something like yahoo or gmail....
