MOTM

As always, when I send an email to Paul I receive this one:

- These recipients of your message have been processed by the mail server:
synth1@...; Failed; 5.1.1 (bad destination mailbox address)

     Remote MTA mx8.airmail.net: SMTP diagnostic: 550 Blocked - see

I need to contact Paul, because I will be away until february 14, so
please delay my shipment (if ready)
thank and sorry for using this ML
