sendmail rule - firstname.lastname recognition
Rainer Fuegenstein
We took over a domain (mydomain.at) and therefore are getting some
emails which we need to redirect, according to the following rule:
if the To: address is obviously "firstname...@mydomain.at" then
rewrite the To: address to "firstname...@mydomain.com" and deliver
it to the MX of mydomain.com. otherwise, apply all other rules as usual.
the best rule for recognition of "firstname.lastname" would be "if there
is a dot and there are at least 3 characters on the left side of the dot
and at least three characters between the dot and the @ then it is
firstname.lastname".
Has someone already written such a rule before ? a m4 macro would be
fine.
tnx in advance,
rainer.

AFAIK sendmail doesn't count letters like that. Rather, letters between
certain punctuation marks are put together in a token. To actually count
the letters you'll probably need a milter script. Otherwise this might
do the trick:
R$-.$-<@mydomain.at> $1.$2<@mydomain.com>

Actually, counting the characters/letters (or rather, requiring a
minimum amount of them) could be done with a regex map, if it's really
needed - implementation left as an exercise etc...

big tnx, I crafted this rule into our mailhost.cf (m4):
FEATURE(nouucp,`reject')
FEATURE(`virtusertable', `btree -o /etc/mail/virtusertable')
[...]
MAILER(smtp)
LOCAL_RULE_2
# re-route sanofi emails
R$-.$- < @mydomain . at . > $1.$2<@mydomain.com>
problem now is that this sendmail config also uses a virtusertable with an
default address defined:
@mydomain.at us...@otherhost.at
I'm not sure to which ruleset the rule above should be added. It seems like only
rulesets 0 to 4 are supported in m4, and ruleset to seems to be to late since
when ruleset 2 is invoked the recipient's address is already us...@otherhost.at
could anybody please give me a hint on where to add this rule in a sendmail 8.11
config ? preferred order is:
ruleset 3 --> domain.at to domain.com rule --> virtusertable lookup --> etc.
tnx in advance.

LOCAL_RULE_0 should do the trick (it happpens just before the
virtusertable lookup).
