What non-standard behaviour features does Gmail exhibit, when it is programmatically used as a POP3 server?
- by Mike Green
I am trying to prepare a complete list of behaviour that Gmail POP3 exhibits, that you wouldn’t expect to generally find in a POP3 server.
For example, Gmail appears to ignore the DELE (delete) command from a POP3 client. Instead, it implements its own delete and archive strategy.
The purpose of preparing a list is to avoid developers testing a POP3 client against the Gmail POP3 server and then assuming that all POP3 servers behave in the same way.
Can anyone provide a more complete list of non-standard behaviour?
