Hi,

Could you give an example of how are you sending those emails?

Also, what version you were using before updating, and did you try going back to older FW to see if that's really the fault of the firmware?

Hi,
Mail programm send message using sockets, protocol smtp, smtp-server port 7100.
Router was connected to embedded computer through cable LAN port.
I was using unknown version of firmware before updating, but the router RUT955 was buyed in 2019.

Hi,

Sorry, router - RUT950, not RUT955.

Another information - true.

Could you please go a few firmware back and see if the issue is gone? I need a confirmation that the new firmware is not working with your process.

I installed ver.RUT9XX_R_00.03.985. (2017.12.14).
All Ok.
Embedded computer send the emails through rut955.
No problems.
But I need new version of firmware.

Hi,

Could you please then try a little newer firmware than 03.985?

I would suggest 06.06.1 version, which is needed to narrow the comparison range, so it would be easier to detect the issue.
