Logging blind spot - size rejects

[Mudgee Host]

HI,

I've come across a blind spot in the proxmox MG.
Messages rejected due to size are not visible at all.

I can find them in the /var/log/mail.log but only with the sender

Jun  7 10:03:36 mx01 postfix/smtpd[18394]: connect from mail-yw1-x112d.google.com[2607:f8b0:4864:20::112d]

As per the attached images they don't exist in the GUI.

1) Could these rejections be made visible somewhere? its all legit email. Would be nice to know about rejects of legit email before my clients clients complain
2) what other reasons besides anti spam are there for rejecting emails - are these also invisible in the GUI?

perhaps we need a reject report?

Answering my own question - Here are the reasons mail is getting rejected on my server over the last two weeks

3957 Recipient address rejected
921 Service unavailable; client [IP] blocked using [RBL]
10 Message size exceeds fixed limit
5 Relay access denied
1 Sender address rejected

the size limit is the odd one out, its all legit
