I have several sites hosted under on hosted virtual dedicated server that
has one primary server where all email comes in. I can not have duplicate
email accounts because of this. I can have multiple domain names on this
account using Apache vhosts.

I migrated two web sites to my VDS. Each had an email account for "joe".
The first one (domianB.com) to move got that name - actually an alias. The
next site to move (domainC.com) had a "joe" associated with it so I added
him as "joseph".

However, old contacts who don't know about the email change still email
joe@domainC.com but it actually gets picked up by joe@domainB.com

I understand why this is happening but hope these is a way to filter or
somehow identify emails intended for joe@domaonC.com and have them go to
joseph@domainC.com?

I have access to edit most of the sendmail files including sendmail.mc

Any ideas are MUCH appreciated!

You do not need to do this. Nor should you as an email administrator
really impose this on clients.

There is. (See below)

Good, you will need to be able to do so.

> Any ideas are MUCH appreciated!

Configure and use VirtUserTable. VirtUserTable allows you to specify
the full email address to a user name mapping. I.e. "joe@domainB.com ->
joe" and "joe@domainC.com -> joseph". Seeing as how you now have people
using "joseph@domainC.com" you need to add "joseph@domainC.com ->
joseph" too.

In short, VirtUserTable abstracts email addresses from the mail box /
user name that they go to. Thus, you can have as many email addresses
with duplicate local (left) parts as you want so long as there is no
duplication within the domain (right) part.

I hope this s. If you want / need setting this up, let us know.

Grant - that is IMMENSELY ful - many thanks.

Here is the pertinent snippet of the VirtUserTable:
joseph@domainA.com joseph
joseph@domainB.com joseph
joseph@domainC.com joseph

joe@domainA.com joe
joe@domainB.com joe
joe@domainC.com joe

If I want joe@domainB to be picked up be the account name joseph I would
change the above to:
joseph@domainA.com joseph
joseph@domainB.com joseph
joseph@domainC.com joseph


joe@domainA.com joe
joe@domainB.com joseph
joe@domainC.com joe

Right?

Then restart sendmail?

Ah, yes, I remember making that same realization about 7 years ago.
Once you go VirtUserTable, you will quite likely NEVER go back. It take
so little to set up and can offer so much.

Yes.

You need to remake the virtusertable map file. The
/etc/mail/virtusertable is really a source file used to generate the map
file that Sendmail uses.

By the way, you do not need to restart Sendmail, as the new map file is
picked up automatically. This is yet again one of the nice things about
virtusertable and maps.

Grant - you have been most ful. Once I edit the "virtusertable" file,
how do I "remake the virtusertable map file"? Do I need to do anything with
"virtusertable.db" or is that what happens when I remake it?

Many thanks again!

You are welcome.

If you are running a map type of "hash" you use this command.

makemap hash /etc/mail/virtusertable < /etc/mail/virtusertable

This will re-generate your virtusertable map file for you. You may need
to replace "hash" with a different type of map depending on how your
system is configured. If you look at the sendmail.mc or sendmail.cf
file on the line that references virtusertable, you should see what map
type to use.

No, as above, this file is the map file and is updated by the makemap
command. Seeing as how you have an extension of ".db" I think you are
running a hash map, so the above command should be good. I believe the
other types of maps are dependent on which operating system /
distribution you are using. Linux tend to use hash.

Many thanks. Now I just have to talk the host into running it. Many thanks
again! You have been very ful.

Grant - my host will not allow me access to use makemap. They use Redhat
Enterprise 4 and I have a test box with centOS. Can I copy the
virtusertable to the test box, makemap there and copy it back, since centOS
is bascially Redhat Enterprise 4?

So much for a drug free work environment.

Now back to our regularly scheduled newsfroup :-)

In theory, if the distors are enough alike (same libraries configured
the same way), probably. However I do not know either one of them well
enough to say yes or no.

Do you not have command line / compilation tool access? If you do, (I
believe) makemap is included with the source of Sendmail so you could
compile your own instance of it and update your virtusertable.

Can I ask, how are you administering your virtusertable now if you don't
have access to makemap? Or are you using a web interface that may take
care of this for you?

Yes, but are there any brownies???

I'm wondering too how Paul maintains his tables without access to the
makemap program.
On the other hand... Sendmail _can_ be told to use plain text tables.
Could that be the case on your system Paul?

From doc/op/op.*:

text Text file lookups. The format of the text
file is defined by the -k (key field num-
ber), -v (value field number), and -z (field
delimiter) flags.

A line like
FEATURE(`virtusertable', `text -k0 -v1 /etc/mail/virtusers')
in your .mc file would configure sendmail to use a plain text file.
The first field on a line will be the key and the second field the
value. The field separator defaults to any white space IIRC.

Performance of plain text lookups will be bad compared with a
hash table. I do NOT recommend this for high volume servers using
hughe tables.

Kees.

hi,

you can map in virtual domain such that joe@domain2.com as
joe.domain2@domain3.com. this would be an internal process. So the no
body in the external can know that the mal is from
joe.domain2@domain3.com. I have already done this but I had problem
with pop3 side changes.

I am managing user accounts from a front-end on my virtual dedicated server.
I am a complete newbie to sendmail.
