Error in sending email

Post by mmi »

Hello,

I tried to send an email to 60 contacts with an attachment and I receive the following error.

said: 400 Unexpected long headers length, got: 5841 want: less than 4096 chars (in reply to end of DATA command))

Any idea what the problem might be?

Regards.

Do you send an email using Apps, webmail or mail client?

Hello,

The best practise : use mailing list. Unless you want to be taken as Spammer.
By default Zimbra is limited to 50 mail adresses (Postfix configuration).
