[Dovecot] outlook problem if TLS mailsettings are off
Dear List,
I dont know if its a dovecot config problem or whatever else issue. Behaviour: If I set /etc/dovecot/dovecot.conf:
Following is valid with IMAP mailboxes only:disable_plaintext_auth = yes # outlook 2007 with TLS in/out enabled can show index of mails and klick on mail does preview / doubleklick opens mail PERFECT AS INTENDED disable_plaintext_auth = no # outlook 2007 with TLS/SSL OFF can show index of mails, but (double)-/klick on mail gives me "sandwatch"-mouspointer and I've to restart outlook again (and enable TLS again to get it work again)
with POP3 mailbox both variants are working smoothly.
Other ssl/tls settings:
ssl_disable = no
login_process_per_connection = yesusing or not using following makes no difference... imap_client_workarounds(default): outlook-idle delay-newmail imap_client_workarounds(imap): outlook-idle delay-newmail pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh
I'm sad - but I can't force SSL/TLS for my users - so I can't "solve" this by using "disable_plaintext_auth = yes" Is there any way out of the dark?
my data:

Sounds like you have some kind of a firewall or antivirus that is capturing the IMAP traffic and breaking it. Try disabling all of them to see if it works then.
No success. I Disabled all firewall rules (enabled for subnet globally all tcp/udp/icmp ports) on firewall appliance and also on PC's I'm testing it with.
Also further tests showed that is not an outlook specific problem for me, also thunderbird shows same behaviour. If I turn TLS in mailclient on - mails in preview get displayed If I turn TLS in mailclient off - mails in preview get not displayed (also opening mail by doubleclick does not work), but login itself send & receive and show index of mails works.
This happens only with IMAP. With POP3 witz/without TLS all working.
Any idea? Any additionl info needed?
