Hi, I have the same problem with the same version of fetchmail package.
I didn't find the fetchmail-dbgsym package, but here is what the suggested command displays: ------------------------------------------------------------------------ $ env LC_ALL=C fetchmail -v -v -v --nodetach --nosyslog -b 2 Old UID list from mail.example.com: <empty> Scratch list of UIDs: <empty> fetchmail: removing stale lockfile fetchmail: 6.4.0.beta4 querying mail.example.com (protocol POP3) at Tue Feb 5 22:22:59 2019: poll started Trying to connect to 12.34.56.78/110...connected. fetchmail: POP3< +OK Dovecot (Debian) 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< STLS fetchmail: POP3< SASL fetchmail: POP3< . fetchmail: POP3> STLS fetchmail: POP3< +OK Begin TLS negotiation now. fetchmail: Certificate chain, from root to peer, starting at depth 2: fetchmail: Issuer Organization: Digital Signature Trust Co. fetchmail: Issuer CommonName: DST Root CA X3 fetchmail: Subject CommonName: DST Root CA X3 fetchmail: Certificate at depth 1: fetchmail: Issuer Organization: Digital Signature Trust Co. fetchmail: Issuer CommonName: DST Root CA X3 fetchmail: Subject CommonName: Let's Encrypt Authority X3 fetchmail: Server certificate: fetchmail: Issuer Organization: Let's Encrypt fetchmail: Issuer CommonName: Let's Encrypt Authority X3 fetchmail: Subject CommonName: mail.example.com fetchmail: Subject Alternative Name: mail.example.com fetchmail: Subject Alternative Name: smtp.example.com fetchmail: mail.example.com key fingerprint: A8:63:B2:92:47:25:A2:89:E5:00:09:F6:80:B2:47:D5 fetchmail: SSL/TLS: using protocol TLSv1.3, cipher TLS_AES_256_GCM_SHA384, 256/256 secret/processed bits 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: mail.example.com: upgrade to TLS succeeded. fetchmail: POP3> USER me fetchmail: POP3< +OK fetchmail: POP3> PASS * fetchmail: POP3< +OK Logged in. fetchmail: selecting or re-polling default folder fetchmail: POP3> STAT fetchmail: POP3< +OK 22 262046 22 messages for me at mail.example.com (262046 octets). fetchmail: POP3> LIST 1 fetchmail: POP3< +OK 1 474 fetchmail: POP3> RETR 1 fetchmail: POP3< +OK 474 octets reading message m...@mail.example.com:1 of 22 (474 octets) About to rewrite Return-Path: <fail2...@example.com>... ...rewritten version is Return-Path: <fail2...@example.com>.
