SEA - SMTP error : Too many connections, slow down.

BenoitS

Hello,

I have this "problem" when sending mass mailing to specific domain (exemple: @orange.fr), thousands of mails are "delivery temporarily suspended" and it take alot of time to send all ...

delivery temporarily suspended : host smtp-in.orange.fr[193.252.22.65] refused to talk to me: 421 mwinf5c15 ME Trop de connexions, veuillez verifier votre configuration. Too many connections, slow down. OFR004_104 [104]

There is a solution using Postfix directly, but is it possible to fix it in Sophos Email Appliance for specifics domain/host ?

I can reduce SMTP destination concurrency/recipient limit in SMTP Options, but it would affect all emails.

If someone has an idea...

Thanks!
