Dear all,

I'm running dovecot # 2.3.2.1 - Pigeonhole version 0.5.2 () - OS:
</div>
<div class="">
Linux 4.18.0-12-generic x86_64 Ubuntu 18.10 with Submission.
</div>
<div class="">
It works great except with apple mail (Iphone).

<div class="">

<div class="">
I get an error with the MTA (postfix):
</div>
<div class="">
""postfix/submission/smtpd[32552]: warning: non-SMTP command from

with other mail-client(s) (Outlook (Desktop and Iphone app)) i have no

Hardly anything to do with Dovecot. When it comes to email clients Apple
</div>
<div class="">
Mail has been and is still one of the worst flops (no offence intended,
</div>
<div class="">
just my opinion based on personal experience). If you can reliably
</div>
<div class="">
reproduce it, try and log the raw SMTP conversation between Postfix and
</div>
<div class="">
the client by enabling per IP debugging in Postfix:
</div>
<div class="">
postconf -e "debug_peer_level = 20"
</div>
<div class="">
postconf -e "debug_peer_list = xx.xx.xx.xx"
</div>
<div class="">
postfix reload
</div>
<div class="">
where xx.xx.xx.xx is the unlucky client IP address.
</div>
<div class="">
<br class="">
</div>
<div class="">
Possibly some crappy SMTP PIPELINING implementation at the Apple end,
</div>
<div class="">
who knows.

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