optonic Posted September 21, 2017 Report Share Posted September 21, 2017 Is it possible to send mails via smtp on port 25 without using starttls. as our global internal exchange server is not supporting this function. Quote Link to comment Share on other sites More sharing options...
Ofir Posted January 23, 2018 Report Share Posted January 23, 2018 There is no option to change the ESMTP/SMTP protocol from UniLogic. Basically we are using standard SMTP/ESMTP protocol and never got complaint about it. You can try using other mail server (he can use public mail server such as Gmail, Hotmail etc..)
