I have a number of domains hosted at a web hosting service. They use sendmail to handle incoming email. I have six domains on this service (which we can call aaa.com, bbb.com and so on). Each email account has the same name and one email box. In other words,
[email protected],
[email protected],
[email protected] and
all the others go into one box, /var/spool/mail/tango, where my email program on my desktop picks it up.
I have done very little work in sendmail. I haven't had to, and I've been warned it's a steep learning curve. But now I'm running into an issue. I was in a business situation where, for years, my email address was on the website for aaa.com. (We won't go into why this was necessary - it wasn't my preference and it's in the past.) Now I'm using
[email protected] instead of
[email protected].
I was getting about 1,000 or more pieces of spam a day, but SpamAssassin and my own email program caught about 75% of that. (Which still left
stuff to delete.) Now, after checking, I see that 90% or more goes to
[email protected], the one that was on the web for years.
I'd like to deactivate
[email protected] and possibly
[email protected] and
[email protected], but want to keep using
[email protected]. Remember, email to tango at any of these domains will go into one email box.
I've had people tell me that sendmail can be configured so I can deactivate
[email protected] (and other domains) and still use
[email protected] (and others, if I want to). In other words, I can configure sendmail to use this account on some domains and not others. One of the people who was teling me this was in
tech support at the hosting service.
But I wrote to
tech support with a work order to do this and now I'm told it can't be done.
I can modify config files myself on this account if needed, but I was hoping to just let them do it. (I love delegation -- it means I spend more time doing my
stuff.)
Is it possible to keep an email account active on one domain and not others with sendmail, when
all domains are hosted on the same server? Is there a name for this process or setting? Any information would be helpful - either pointers to instructions so I can do it, or enough info so I can tell
tech support, "This is where to look, and it can be done, so please pass my request on to someone who works with sendmail and knows how to do it."
Is this something sendmail can do?
