I change the pop3 client config for our users :

Now in local account field I enter the external email address (user1@company.com)

 Everything seems to be OK

We are using Mercury mail c 4.01B as mail server.

The mails from the outside are popped from our ISP mail server.

 The local domain name is company.priv

The domain name  from the Internet is company.com

We create one local account by user , mine is v-luce with local email address v-luce@company.priv

Then we create one alias per user, v-luce@company.com, and we configure mercury pop3 client  to pop mail on ISP mail server.

When I create and automatic reply by adding a  areply.cfg file in mail box directory I have problem with email sent from the outside.

When an email is sent from the outside the from address in the automatic response is v-luce without any domain name, it should be v-luce@company.com.

I tried to configured synonym.mer file but it does not seem to work...

synonym.txt content (converted to synonym.mer with fsynonym.exe) :

v-luce@company.com == v-luce

I hope it's clear, ...

Is the To: header within the mail correct? or is it re-written?

Otherwise, try to add among the domains section your company.com

Areply routine (I believe) is formed by using the To: header if it matches your config as the From: when forming the areply.

I have a problem into the from field in the automatic response mail.

See below the header of the automatic response. I sent an email from test@free.fr to v-luce@company.com

In the header of the automatic response the FROM field contain  v-luce. It should be v-luce@company.com

How are you delivering the mail via POP3?  If you are using a simple local username then the X-Envelope-To: address will be the local username instead of a full SMTP email address.  Since this address is used in the forwarding as the MAIL FROM: address it will fail.

You need to leave the local username blank and then alias v-luce@company.com to a full SMTP address v-luce@company.priv for this to work.  In any case, check the headers on a received message.  If the X-Envelope-To: does not have a full SMTP address then you have not yet got it right.  ;-)

Thanks a lot, that solved  my problem.

 For each pop3 client config I used to enter the local user and default user. If I leave these two fields empty then Mercury mail use the alias to find the correct mail box to deliver the mail. Then, the automatic response use the destination address to fullfill the From field.

 Thanks again,

I have a problem with this new way to configure pop3 client.

 If a mail is sent to two users : user1@company.com and user2@company.com

then this mail will be duplicated in each user's mailbox on our ISP's mail server. 

When Mercury mail pops  user1 mailbox on the ISP server it wil deliver the to user1 and user2 using aliases

When Mercury mail pops  user2 mailbox on the ISP server it wil deliver the to user1 and user2 using aliases

User1 and user2 will receive the mail twice

If each user has their own mailbox at your ISP, then you should enter only a 'local user' on the MercuryD definition so that all the mail from that mailbox will go to just one user.  In that way there will be no interpretation of the To:, Cc: etc. headers and is easier to manage.
