Dear Eric, One of my server seems getting session block on imap. I am unable to log on webmail or even unable to telnet on 143 port. After restarting dovecot, I can log immediately but if I wait 30 sec to one min, again I am unable to log in. Below are the reports:
telnet: [root@client html]# telnet localhost 143 Trying ::1... Connected to localhost. Escape character is '^]'. Connection closed by foreign host. [root@client html]# [root@client html]# systemctl restart dovecot [root@client html]# telnet localhost 143 Trying ::1... Connected to localhost. Escape character is '^]'. * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE STARTTLS AUTH=PLAIN AUTH=LOGIN AUTH=DIGEST-MD5 AUTH=CRAM-MD5] Dovecot toaster ready. a logout * BYE Logging out a OK Logout completed. Connection closed by foreign host. [root@client html]# Log: master: Warning: service(imap-login): process_limit (100) reached, client connections are being dropped -- -- Best Regards Muhammad Tahnan Al Anas
