HI

I would like to change just the part of username (of recipient).
I want to rewrite the any adrress 123xxx@dom.com to 321xxx@dom.com (to
change 123 with 321).
For example 123911@dom.com to 321911@dom.com

Can somebody show me the way this should be done

Thanks

Perhaps all you need is the virtusertable feature.

See cf/README

virtusertable A domain-specific form of aliasing, allowing multiple
virtual domains to be hosted on one machine. For
example,
if the virtuser table contains:

info@foo.com foo-info
info@bar.com bar-info
joe@bar.com error:nouser 550 No such user
here
jax@bar.com error:5.7.0:550 Address invalid
@baz.org jane@example.net

(there is lots more there)

To extend this to support localpart only rewriting see

http://www.jmaimon.com/sendmail
http://www.jmaimon.com/sendmail/patc...oto.m4.3.patch

Or there is the genericstable, aliases and address rewriting in either
localaddr or parseaddr.

Thanks for reply!

If I understood well I need to install some additional stuff to
Sendmail? I preffer not to do it because my sendmail serving live
service and I am not so good.

Is there any other way that not require additional installing and
similar things?

I dont understand what you are trying to achieve well enough to answer
any more than I already did.

If you are trying to do exactly as your example shows, than vanilla
virtusetable with or without virtuserdomains (if the domains arent
local) will do just fine.

Hi and sorry if I was confusing.
I'll try to explain what exactly I want to have.
Mails addressed to:
123000000@domain.com
123000001@domain.com
.....................................
123999998@domain.com
123999999@domain.com


should be delivered to
321000000@domain.com
321000001@domain.com
.....................................
321999998@domain.com
321999999@domain.com
respectively.
So, instead of having 999999 entries in some place i would like to have
few lines that change first three characters of user part. This should
happen only if those three lchars are 123 (they should be changed to
321). Rest of user part should remains as it was before.

Hope this is understandable.

Thanks

Since sendmail tokenizing means that you will have few chances to deal
with a subset of the localpart you may be best off by constructing a
program map shell script that does the translation you want

(see doc/op/op.txt)

Then you can follow the suggestions in this post (is there a new/better
way?) to get sendmail to use both your map and the normal virtusertable
map.

Well, it should be doable with a regex map.

>(see doc/op/op.txt)

Ditto.

If you want to combine different maps into one (i.e. not just different
*text files*, where you're better off sending the concatenation as input
to makemap), that's still the way to go AFAIK. Not sure if it's needed
here though, it seems clear that the OP isn't using the virtusertable
already so this could be used as the *only* map for virtusertable - or
it could just be a couple of custom rules for LOCAL_RULE_0.

Hi,
i have tried with regex. In that way from initial 123000000@domain.com
I can get 321 000000 @ domain . com
Because of space between 321 and 000000 final result will be
321.000000@domain.com which is not good for me.
Is there any chance to fix this (remove space)?
Thanks
