socat[122] E write(6, 0x5ab150, 21): Broken pipe

[ronaldt80]

Thanks for all the work. I installed the bridge following instructions. Running 1.4.5-build on a Pi3B+ which I want to address from other machines on the network.

When I enter the SMTP server in Unifi the test-email generates an error, at the same time a log error appears in the proton mail bridge (so at least something happens..) - no clue what it means though and where to start:

2021/05/05 19:44:09 socat[122] E write(6, 0x5ab150, 21): Broken pipe

Many thanks for any suggestions!

Addition 22:08 CET - I tested IMAP with Mozilla Thunderbird and added the SMTP account to Nextcloud; both work flawlessly

It might be related to the self signed TLS cert the bridge uses. Can you ignore TLS check or disable TLS in Unifi?

Hi, I have the same problem. But running in kubernetes.

I have a service that re-routes contact form from website.

First mail goes to my protonmail inbox.
Second mail goes to sender / client from website.

First try did all good, I received email both on my protonmail inbox and other "sender" email.

Second try I received this:
socat[34650] E write(5, 0x5c0a9ee389f0, 40): Broken pipe
And email came just to my protonmail inbox, sender did not receive anything.

Additional 10 tries did the same as second try.

After ~1 hour
everthing was fine again for first try.
Second try no one received mail and I get 2 messages each time I try:
socat[34650] E write(5, 0x5c0a9ee389f0, 40): Broken pipe

So it seams when this appears emails wont go through anymore.
Did not have time to test it more yet but when I do will post update.

@vpresecki Hey, I'm wondering what the cause of this is too. Did you learn anything?

No, still happening. Could not resolve it.
