Hi, I've attempted upgrade of my postfix docker container from alpine 3.8 (which has postfix 3.3.0) to alpine 3.9 (postfix 3.3.2). Perfectly working config which just worked with 3.3.0 now causing SASL auth error: warning: SASL authentication failure: No worthy mechs found
Here is verbose logging from container: smtp_1 | 2019-02-16T04:33:01.621125+00:00 xxx postfix/smtp[106]: < host.domain.com[IP.ADDRESS]:587: 250-host.domain.com smtp_1 | 2019-02-16T04:33:01.621166+00:00 xxx postfix/smtp[106]: < host.domain.com[IP.ADDRESS]:587: 250-PIPELINING smtp_1 | 2019-02-16T04:33:01.621170+00:00 xxx postfix/smtp[106]: < host.domain.com[IP.ADDRESS]:587: 250-SIZE 104857600 smtp_1 | 2019-02-16T04:33:01.621174+00:00 xxx postfix/smtp[106]: < host.domain.com[IP.ADDRESS]:587: 250-VRFY smtp_1 | 2019-02-16T04:33:01.621177+00:00 xxx postfix/smtp[106]: < host.domain.com[IP.ADDRESS]:587: 250-ETRN smtp_1 | 2019-02-16T04:33:01.621182+00:00 xxx postfix/smtp[106]: < host.domain.com[IP.ADDRESS]:587: 250-AUTH PLAIN LOGIN smtp_1 | 2019-02-16T04:33:01.621186+00:00 xxx postfix/smtp[106]: < host.domain.com[IP.ADDRESS]:587: 250-AUTH=PLAIN LOGIN smtp_1 | 2019-02-16T04:33:01.621191+00:00 xxx postfix/smtp[106]: < host.domain.com[IP.ADDRESS]:587: 250-ENHANCEDSTATUSCODES smtp_1 | 2019-02-16T04:33:01.621196+00:00 xxx postfix/smtp[106]: < host.domain.com[IP.ADDRESS]:587: 250-8BITMIME smtp_1 | 2019-02-16T04:33:01.621199+00:00 xxx postfix/smtp[106]: < host.domain.com[IP.ADDRESS]:587: 250-DSN smtp_1 | 2019-02-16T04:33:01.621203+00:00 xxx postfix/smtp[106]: < host.domain.com[IP.ADDRESS]:587: 250 SMTPUTF8 smtp_1 | 2019-02-16T04:33:01.621215+00:00 xxx postfix/smtp[106]: match_string: smtp_sasl_mechanism_filter: plain ~? auth smtp_1 | 2019-02-16T04:33:01.621314+00:00 xxx postfix/smtp[106]: match_string: smtp_sasl_mechanism_filter: plain ~? login smtp_1 | 2019-02-16T04:33:01.621326+00:00 xxx postfix/smtp[106]: match_list_match: PLAIN: no match smtp_1 | 2019-02-16T04:33:01.621330+00:00 xxx postfix/smtp[106]: match_string: smtp_sasl_mechanism_filter: login ~? auth smtp_1 | 2019-02-16T04:33:01.621334+00:00 xxx postfix/smtp[106]: match_string: smtp_sasl_mechanism_filter: login ~? login smtp_1 | 2019-02-16T04:33:01.621406+00:00 xxx postfix/smtp[106]: match_string: smtp_sasl_mechanism_filter: plain ~? auth smtp_1 | 2019-02-16T04:33:01.621415+00:00 xxx postfix/smtp[106]: match_string: smtp_sasl_mechanism_filter: plain ~? login smtp_1 | 2019-02-16T04:33:01.621418+00:00 xxx postfix/smtp[106]: match_list_match: PLAIN: no match smtp_1 | 2019-02-16T04:33:01.621422+00:00 xxx postfix/smtp[106]: match_string: smtp_sasl_mechanism_filter: login ~? auth smtp_1 | 2019-02-16T04:33:01.621425+00:00 xxx postfix/smtp[106]: match_string: smtp_sasl_mechanism_filter: login ~? login smtp_1 | 2019-02-16T04:33:01.621432+00:00 xxx postfix/smtp[106]: server features: 0x20902f size 104857600 smtp_1 | 2019-02-16T04:33:01.621451+00:00 xxx postfix/smtp[106]: Using ESMTP PIPELINING, TCP send buffer size is 87040, PIPELINING buffer size is 4096 smtp_1 | 2019-02-16T04:33:01.621522+00:00 xxx postfix/smtp[106]: maps_find: smtp_sasl_password_maps: host.domain.com: not found smtp_1 | 2019-02-16T04:33:01.621540+00:00 xxx postfix/smtp[106]: maps_find: smtp_sasl_password_maps: hash:/etc/postfix/sasl_passwd(0,lock|fold_fix|utf8_request): [host.domain.com]:587 = username:password smtp_1 | 2019-02-16T04:33:01.621552+00:00 xxx postfix/smtp[106]: smtp_sasl_passwd_lookup: host `host.domain.com' user `username' pass `password' smtp_1 | 2019-02-16T04:33:01.621599+00:00 xxx postfix/smtp[106]: starting new SASL client smtp_1 | 2019-02-16T04:33:01.621650+00:00 xxx postfix/smtp[106]: smtp_sasl_authenticate: host.domain.com[IP.ADDRESS]:587: SASL mechanisms LOGIN smtp_1 | 2019-02-16T04:33:01.621668+00:00 xxx postfix/smtp[106]: warning: SASL authentication failure: No worthy mechs found Could you please point me into correct directions on what's causing SASL auth failure?
