Hello,

Today I was figure out why cant I sent attachment in emails for example to gmail from internatl network. We are using Lotus domina and spohos is gateway.

If I attach for example word_document.docx;zipped file... and sent to gmail I see in mail log only this:

2016:08:31-08:10:52 mail-1 exim-in[25009]: 2016-08-31 08:10:52 [192.168.101.232] F=<Filip.XX@my-domain.cz> R=<filip.corsair@gmail.com> Accepted: from relay

Nothing more and next day I getreturn mail with reason ,, Delivery time expired" is it problem with sophos or IBM Lotus server ?

Thank you for any help.
