AlterMIME from external clients

[bswinnerton]

Hi there,

I just followed the how-to (http://www.howtoforge.com/how-to-aut...n-debian-lenny) on setting up AlterMIME on my server, and everything is working from my webmail client (roundcube), but on external clients such as Apple Mail and Blackberries do not show the signature. How can I resolve this?

Are there any errors in your mail log (in the /var/log/ directory)?

[bswinnerton]

No, nothing at all. But I did notice that the emails don't appear to be sent from my mail server, instead from the ip address of the actual SMTP client. Here is what a sample mail send looks like in mail.info:

I'm sorry, but I have no idea why it's not working...

Hi bswinnerton

Did you solve this? I have this problem, too.

Thanks for your answer.
