Sending e-mail timeout

Hello,

I’ve set up MikroTik to send e-mails. It works fine - I can send email with attached file without any problem. But if I try to send e-mail with larger file, after 60 sec I get this error:

System-Error: Error sending e-mail: abnormal termination (timeout)

I checked interface’s Tx/Rx while sending e-mail with file and I can see Mikrotik is uploading attached file. If the file is small enough so Mikrotik can upload file within 1 min, e-mail passes with no error. But if I attach larger file that Mikrotik can’t send within 1 min I get error I wrote above. Is possible to change timeout of sending e-mail? Or is there any other way to solve this error?

Thank you in advance

I tested it on x86 platform with ROS v3.28. Same thing on RB433, ROS v3.28 and 4.0beta4.
