Configure sendmail to forward particular emails via ISP SMTP server...

[Andrew Bruce]

Hi folks,

Sendmail is a fairly black art to me!

I have a server up and running with (amongst other things) a sendmail daemon that is working fine.

However, due to some short-sightedness of a certain mobile phone company (let's call them 'voodoofone'), if I try to forward emails from my server to my mobile phone, the emails get bounced by the voodoofone server claiming that all dynamic IPs are sources of spam, therefore the email is spam, therefore voodoofone will not upset their valued customer (even though the email is *FROM* their valued customer!).

Anyway, I digress...

I see how to configure sendmail to re-route *ALL* emails via my ISP SMTP server (from http://cri.ch/linux/docs/sk0009.html), but I don't want to do this.

All I want to do is to re-route *only* the outbound emails destined for my mobile phone (lets call the address: myfone@voodoofone.net) through my ISP's SMTP server.

Everything else should be sent out as normal from my SMTP server.

Essentially, I have a particular user account that has a .forward file configured simply forwarding all emails to my mobile. All the other user accounts should be unaffected.

Anyway, any pointers or advice would be greatly appreciated (vizzavi points :-)

Regards,

Andy Bruce

I suggest:

.forward file for the user.

This points to another .forward file or system with a virtusertable on a system that either has a fixed IP address or a DS directive in sendmail.cf to a machine with an acceptable fixed ip address.

I know it seems obtuse but it will work.

Thanks Sep,

I'll need to investigate your suggestion a bit further - you're right, it is a bit convoluted! :-}

Any other solutions still welcome though!

Thanks and regards,

I think that you can use Mailertable.

Thanks Ivan,

Your suggestions lead me to looking at the mailertable:

Added an entry into /etc/mail/mailertable:

voodoofone.net smtp:[smtp.myisp.co.uk]

Now, any outbound mail going to the voodoofone.net domain gets rerouted via my ISPs smtp server.

What's more, it *works*!

Now I just have to filter out the spam! ;-)

Thanks all for your input!

Solution discovered!

(Apart from RTFM), put an entry into mailertable (see previous response).

Thanks again!
