Hi,
I am running 12.2-STABLE and VNET jails, one of which host a recent Dovecot
IMAP and a recent postfix SMTP server. Authentication is forced via TLS/SSL for
both services (ports 587 and 993). Setup is as follows:
extIF0/pf/NAT <—> epairXa (bridge0) epairXb <-> jail
A recent upgrade broke mailing of IMAP clients running at macOS 10.14.6
(Mojave) und AVM's push service (Fritzbox), but *not* for IMAP clients running
at macOS 10.15.7 (Catalina). Strange.
Findings at macOS 10.14.6 (examplified for IMAP):
1) mac$ nc -4vw 1 mail.xyz.zzz 993
found 0 associations
found 1 connections:
1: flags=82<CONNECTED,PREFERRED>

Connection to mail.xyz.zzz port 993 [tcp/imaps] succeeded!
2) mac$ openssl s_client -crlf -connect mail.xyz.zzz:993 -debug

hanging at that stage forever
(and client complaining of its inability to authenticate and reports
timeout after 60 seconds)
I did identify commit 367740 being responsible for that:
mike> svn up -r 367740
Updating '.':
U sys/netinet/ip_fastfwd.c
U sys/netinet/ip_input.c
U sys/netinet/ip_var.h
U .
Updated to revision 367740.
Any Ideas, especially why clients at different OS behave different?
FYI: I do have no access to AVM's push service, and very limited access to the
macOS 10.14.6 computer.
Thanks in advance and with kind regards,
Michael
P.S. How may I update a local svn copy and simultaneously omit commit 367740
from being applied, or how may I revert commit 367740, only?
