Duplicate sent emails.

[Keith P Hassen]

Hello,

First, I think that roundcube is a slick web application, good job!  
Second, when I send email, it sends exactly two emails (perfect 
duplicates of each other) to the destination, not just one.  It does 
this whether I send email within my domain, to other domains, etc.  I 
have not been able to determine why, without examining the code more 
closely.

Suggestions?

Thanks,
