Description

I have a program that talks both HTTPS and SMTP.

The HTTPS phase goes fine in Proxychains but after this it hangs on the SMTP request (forever / no time-out / no error)

[proxychains] Strict chain ... 111.22.33.44:1080 ... 55.66.77.88:587 ... OK

The most important parts of my config (excluding port 587 did not help):

## Exclude connections to ANYwhere with port 587
localnet 0.0.0.0:587/0.0.0.0

[ProxyList]
socks5 11.22.33.44 1080
socks5 99.99.99.99 1080

Research direction

Reproduce the hang with a program that performs HTTPS followed by SMTP through the configured strict SOCKS chain, using port 587 and the shown localnet exclusion. Compare behavior with and without the exclusion; done means the SMTP request either completes or fails with a timeout/error, rather than hanging indefinitely.
