Mail has been and is still one of the worst flops (no offence intended,

just my opinion based on personal experience). If you can reliably

reproduce it, try and log the raw SMTP conversation between Postfix and

the client by enabling per IP debugging in Postfix:

<div>
postconf -e "debug_peer_level = 20"

postconf -e "debug_peer_list = xx.xx.xx.xx"

postfix reload

Possibly some crappy SMTP PIPELINING implementation at the Apple end,

It's not unconceivable that there are bugs in submission either. Can you
provide doveconf -n and submission rawlogs? See
https://wiki.dovecot.org/Submission for settings.

Hi, did you see this thread? https://dovecot.org/list/dovecot/2018-October/113348.html <https://dovecot.org/list/dovecot/2018-October/113348.html> Had a similar issue with CHUNKING and Apple Mail, but could reproduce it with a Perl script, too. But I do not whether this was fixed already in v2.3.4 (nothing found in the release notes). Could be that relaying PIPELINING hast the same issues with ?multi-line replies?. Regards, Paul> On 18.
