Dovecot Problem

pixel8
Hello, hi to all, i just joined this forum, i've read a lot of posts but i have not resolved my problem. I have a problem with Dovecot&Interspire. I have installed Interspire on a VPS, i have also installed on the same vps WHM/Cpanel to set the SMTP/IMAP/POP3 server with services Dovecot and Exim. The SMTP from Interspire works correctly and the mails are sent correctly, i had to change in "Options for OpenSSL" from "+no_sslv2 +no_sslv3 +no_tlsv1 +no_tlsv1_1" default to "+no_sslv2" and with second option it works. I have Autossl active with Cpanel certificate. While if I try to connect with Interspire to POP3/Imap server, it doesn"t work, on Interspire remain on: "Connecting to Mail Server...Please wait while we attempt to connect to your mail server." While with other client i login in POP3/Imap server correctly and read the mails. Dovecot log is: dovecot: imap-login: Disconnected (disconnected before auth was ready, waited 0 secs): user=<>, rip=x.x.x.x, lip=x.x.x.x, secured, session=<4+KTKL11grxf2KdX> dovecot: imap-login: Disconnected (no auth attempts in 0 secs): user=<>, rip=x.x.x.x, lip=x.x.x.x, secured, session= mail dovecot: pop3-login: Disconnected (no auth attempts in 0 secs): user=<>, rip=x.x.x.x, lip=x.x.x.x, secured,
I tried to add others ssl protocols in dovecot conf but it give me always the same problems/errors. How could i solve? Th info of my VPS: /etc/redhat-release:CentOS Linux release 7.5.1804 (Core) /usr/local/cpanel/version:11.74.0.6 /var/cpanel/envtype:kvm CPANEL=release
Thank you for help

    Hi @pixel8 Just to be sure are you making configuration changes for dovecot at WHM>>Service Configuration>>MailServer Configuration or are you making them directly to the dovecot configuration file? As a warning, any changes you make manually will be overwritten the next time dovecot is restarted. What are the SSL protocols you're allowing in the MailServer Configuration? Thanks!

    Hello Lauren, thank you for response. Yes, i did some mods in "MailServer Configuration" on WHM and when i did mods on dovecot.conf i haven't restarted Dovecot from WHM just to not overwrite the changes. Now i have this protocols in "SSL Protocols": TLSv1 TLSv1.1 TLSv1.2 SSLv2 SSLv3, but i tested with all singles without success.

    Hi @pixel8 Do you see something in the logs indicating the issue is an SSL protocol issue? I found some documentation on the 3rd party software Interspire here that might be worth a read: Interspire The error here: dovecot: imap-login: Disconnected (disconnected before auth was ready, waited 0 secs): user=<>, rip=x.x.x.x, lip=x.x.x.x, secured, session=<4+KTKL11grxf2KdX>
    Makes me wonder if something else isn't going on. Ultimately though it may be most efficient to troubleshoot this issue with the help of their support Interspire

    When i try to connect to Imap/pop3 server, maillog give me only the error quoted. All server requirements are ok, SMTP with exim by Interspire works correctly. I think it's the ssl but I'm not sure, because if I try on google that error, they always talk about SSL / TLS. I have already contacted the Interspire support, I am waiting for an answer. Thank you

    Hi @pixel8 I would check with them (if it is an SSL/TLS issue) whether or not they use standard ciphers - They should be able to provide you the ciphers they support as well as protocols. Thanks!
