This 5 minutes time out may be from the other end or any intermediate network node (if there is any). You can check this by starting communication trace in IBM i (specifying the other end node's IP address if you know so the trace file is kept small) and send the mail again and stop the trace when time out occurs. Then dump the trace to IFS file (in PCAP format) and use Wireshark tool to check from which IP address the connection termination is from. If the IP sending connection termination is not from IBM i, then you know it's from outside network node.

Subject: SMTP Timeout 5 minutes?
I am having issues with SMTP Client timing out after 5 minutes sending attachments to GMAIL. I cannot seem to locate the setting for this? the connection is slow. the attachment is not that large. smaller attachments ok, and sending email notes ok. Any advise on where this can be adjusted?

If i attach a slightly smaller file it goes through ok. it s a simple PDF attachment.
thank in advance for any tips.
