Package: fetchmail Version: 6.4.39-1 Severity: normal I have observed occasionally this bug starting one year ago (approximately) while downloading email from two different servers. In all cases fetchmail stops downloading midway through a long message with a socket error and leaves the message on the server. There is no way out: next time it polls, the same thing happens and no new mail is downloaded. Only cure I found, login through webmail and delete the offending message, which is tyipically a big spam message. Here is the lastest instance seen on the log:
fetchmail: reading message u...@email.addr@provider.smtp.server:3 of 40 (3310505 octets) (log message incomplete) fetchmail: socket error while fetching from u...@email.addr@provider.smtp.server fetchmail: Query status=2 (SOCKET) Fetchmail stops on error and retries indefinitely, but gives no sign of this situation, so I am not alerted of it unless I notice that no mail is arriving. Fetchmail should detect this situation and at least send an email signaling the problem. At best, it could additionally mark the offending message and skip it. Here is the same log as above with -v. Info is obfuscated, but I will gladly send the onubfuscated log privately upon request. + provider.smtp.server at 2025-01-21 17:54:04+0100 fetchmail: Trying to connect to 79.98.45.16/110...connected.
