Slow e-mail sending in 16.1

[lobokn]

Hi Ralf,
I am testing EGW 16.1 on debian 8.5 . And when I try to send e-mail it always takes about 15 seconds
before message window disappears. I have EGW on different server than mail-server is.
Could be this the reason ? I have PHP7, OpCache and APC installed and enabled.

Can you give me any advice. What to try to speed it up ?

Many thanks

Lubos

I finally found the solution to the problem. It has connection with settings of SMTP authentication
in EGW and settings in postfix.
I just checked Authentication check box in SMTP settings and sending of e-mails is much more faster.
