Hi all,

So many messages on this so full-of-life list,
but not a reason for not thanking for your help.

Yes I do know and use the manual connection w/ telnet 25 ans SMTP sequence.
I didn't realize on the other hand that the checks were made at this

allowing some of the recipients while rejecting other ones.

Gotta try this ASAP,

Thanks once more,

regard,

Laurent.
