Mail with "-" char couldn't be sent

We have an Streamserve app which uses our smtp server in Domino/Notes and it sometimes automaticly will sendan email to two externa email addresses with a PDF file as an attachment. Both recipient addresses (To: field) contains a “-” char in the who part before the @domainname, ie, jim.anderson-stockholm@domainname.com och ben.pearson-stockholm@domainname.com. When we look inside the Domino/Notes log the attempt is to mail to the following to addresses,

tim.anderson-stockholm@domainname.com, " jim.pearson-stockholm"@domainname.com

It put in one blank char and two " chars before the @ char for the second address in the field. With one address it’s ok. It’s also ok with many addresses as long as the name part of the email address do not have the “-” char.

If anyone seen this before please let me know.

Is it possible to log what’s been sent to the smtp server in Domino/Notes from an external application as in the above case?

I would appreciate any comment on this.

TIA
