The problem is found by fetchmail, which fails to fetch mail from a remote mailserver (runing postfix+dovecot)

The console output looks like: admin@localhost:~> fetchmail -v --ssl mail.openqa.suse fetchmail: 6.3.26 querying mail.openqa.suse (protocol POP3) at Wed 06 Sep 2017 03:12:03 PM CST: poll started Trying to connect to 10.67.18.229/995...connected. fetchmail: Server certificate: fetchmail: Issuer Organization: SUSE fetchmail: Issuer CommonName: openQA CA fetchmail: Subject CommonName: mail.openqa.suse fetchmail: mail.openqa.suse key fingerprint: 4E:FD:84:BE:B5:6C:BF:B0:75:F2:F4:EF:E8:7F:50:9E fetchmail: POP3< +OK Dovecot ready. fetchmail: POP3> CAPA fetchmail: POP3< +OK fetchmail: POP3< CAPA fetchmail: POP3< TOP fetchmail: POP3< UIDL fetchmail: POP3< RESP-CODES fetchmail: POP3< PIPELINING fetchmail: POP3< AUTH-RESP-CODE fetchmail: POP3< USER fetchmail: POP3< SASL PLAIN fetchmail: POP3< . fetchmail: POP3> USER admin fetchmail: POP3< +OK fetchmail: POP3> PASS * fetchmail: POP3< +OK Logged in. fetchmail: POP3> STAT fetchmail: POP3< +OK 2 1446 fetchmail: POP3> LAST fetchmail: POP3< -ERR Unknown command: LAST fetchmail: Unknown command: LAST fetchmail: POP3> UIDL fetchmail: POP3< +OK fetchmail: POP3< 1 00000016599145ec fetchmail: POP3< 2 00000017599145ec fetchmail: POP3< . 2 messages for admin at mail.openqa.suse (1446 octets). fetchmail: POP3> LIST 1 fetchmail: POP3< +OK 1 741 fetchmail: POP3> TOP 1 99999999 fetchmail: POP3< +OK reading message admin@mail.openqa.suse:1 of 2 (741 octets) Trying to connect to ::1/25...connected. <fetchmail hangs here>

The system journal disclosures the real issue: Sep 06 15:03:49 localhost postfix/smtpd[3442]: fatal: bad string length 0 < 1: smtpd_sasl_path = Sep 06 15:03:50 localhost postfix/master[2712]: warning: process /usr/lib/postfix/smtpd pid 3442 exit status 1 Sep 06 15:03:50 localhost postfix/master[2712]: warning: /usr/lib/postfix/smtpd: bad command startup -- throttling

The error can be fixed by editing the configuration file /etc/postfix/main.cf, comment out the following lines: smtpd_sasl_path = smtpd_sasl_type =

Note: the new lines look like: #smtpd_sasl_path = #smtpd_sasl_type =
