MimeWriter and smtplib: long list of 'To:' recipients

[Gillou]

Steve,

Thanks a lot for your reply. Here is some more information...

This code does not trigger any exception. In debug mode, the smtp server did
not reply anything noticeable pertinent to my problem.

I sent a mail to a long list of recipients with different mail clients (IE5
and StarOffice mail). The difference I noticed is that these mail clients
split the "To" line in multiple lines, the second line (and following)
beginning with some spaces like this:

To: mymother at herisp.net, mygirlfriend at bed.org,
    mybrother at home.com, myboss at hell.org

When the Mimewriter.addheader('To', samelistofrecipients) writes all in one
long line.

Is there some limitations in the SMTP protocol (or other related rfc)
regarding the length of an header line ?

Happy Christams
