Roundcube takiing too time for sending an email trougt postfix+lmtp+dovecote

[ste74]

Hi ,

I ve just configured a system :
RC latest
postfix latest
dovecote latest

RC is running on nginx + php-fpm
i dont understand why is taking much more of 10 second to complete the POST after clieck SEND even if the smtp on the same network and not under workload .

someone could help ?

I think i found the culprit : at SMTP server layer with a DNS latency too high slowing down the get the response .

Improve DNS so
