Issue after upgrading to new dovecot

[rcubeuser]

Hi, I have upgraded my whole email server to a new one(including my roundcube). And I noticed that a few emails it throws:

Internal error
Could not load message from server

I found only one error in dovecot log

Code: [Select]

Feb 08 14:20:29 imap(my@mydomain.com)<1446624><1c4zSi/0DMZ/AAAB>: Error: Mailbox INBOX: UID=10758: read(<binary stream of mailbox INBOX UID 10758>) failed: read(/var/vmail/mydomain.com/my/Maildir/cur/1565624641.M893186P552292.myhostname,S=12716,W=12907:2,S) failed: Invalid quoted-printable input trailer: '=' not followed by two hex digits

I suspect that there is a problem between roudncube and dovecot, because this problem does not exist between outlook and dovecot.

My roundcube version is 1.4.11 (same on the older server).

My dovecot version on new server is 2.3.16, older server: 2.2.22;

P.S. On older server  I never had this issue.
P.S.S Sorry for my english.

Why you not upgrade RC to 1.6.1 ?

This looks like a dovecot bug, but you can try $config['imap_disabled_caps'] = ['BINARY']; in Roundcube config.

This solution(that I liked most) worked.

One more thing, does roundcube 1.6.1  requires php version to be at least 7.3?

Yes.
