Hi

I use fetchmail to get my mail from maddy via imap.

Fetchmail complains about synchronization error which is caused (i think) by the extraneous line about 8452:

    fetchmail: IMAP> A0009 FETCH 8453 RFC822.HEADER
    fetchmail: IMAP< * 8452 FETCH (FLAGS (\Recent \Seen))
    fetchmail: IMAP< * 8453 FETCH (RFC822.HEADER {971}

(full log is attached)

Should fetchmail expect/ignore the 8452 line or is maddy confused?

# maddy -v
maddy 0.5.2+3ae0704 linux/amd64 go1.16.8

thanks
 chris

Hi.

Looks like a problem caused by maddy's asynchronous update dispatcher. While technically it is not violating any standards, it confuses some clients. Unfortunately, there is no easy solution short of rewriting it from scratch which is not completed yet (tracked in https://github.com/foxcpp/maddy/issues/188).
Perhaps you could try a different synchronization tool in meanwhile (e.g. getmail?).
