Hi Everyone,
I have a query which I hope others may find interesting as well.
The company that I work for has users that subscribe to many different mailing lists for marketting and informational purposes.
What I would like to be able to do is centrally manage this internally so that only one copy of the message is received regardless of the number of people subscribed to each list which we can then either deliver the message internally to anyone interested or via public folders on Cyrus IMAP/MS Exchange.
The second thing I would like to be able to do is allow people to send to the appropriate list but for their email address to be rewritten to that of the registered email address of the list therefore everyone in the company who is subscribed to the list gets the replies.
I am guessing that the following steps would have to be done:-
* Setup an internal email account for each list (e.g. centos-list@companya.com) * Configure sendmail to either forward the message onto the exchange server and store in public folders or use filtering rules to deliver it to the appropriate Cyrus mailbox. * Maintain a list of all mailing lists subscribed to and have sendmail rewrite the from headers if anyone tries to send a message to one of the registered list addresses.
I'm sure I've forgotten things here but I haven't got a clue how to set this up. Is this possible using the included programs with Centos (Sendmail, Cyrus IMAP, procmail)?
As a second query but still related is it possible for sendmail to rewrite incoming email addresses? At the company we have various addresses in the format of firstname.surname.ext@company.com (where ext could be support or devel, etc). At present we setup distribution lists on exchange for everyone of these addresses for every user and it is becoming a management nightmare. What I would like to be able to do is for sendmail to notice this double-dot format and based on the ext bit to forward it onto the appropriate user as well as the relevent catch all address (i.e. send to firstname.surname@company.com and then also send to ext@company.com).
Sorry if this is a bit long winded but hopefully I've explained clearly enough for someone to offer some insight
Thanks in advance
Regards
Lee
