Hello All: I have an odd problem. My platform is: jserink@jserinki7 ~/qemu/vde $ uname -a Linux jserinki7 4.4.6-gentoo #6 SMP PREEMPT Wed Jun 1 04:58:45 EST 2016 x86_64 Intel(R) Core(TM) i7-2720QM CPU @ 2.20GHz GenuineIntel GNU/Linux jserinki7 vde # equery list evolution * Searching for evolution ... [IP-] [ ] mail-client/evolution-3.20.4:2.0 jserinki7 vde # equery list evolution-data-server * Searching for evolution-data-server ... [IP-] [ ] gnome-extra/evolution-data-server-3.20.4:0/57 When I am in the office or our home, I have no problems using evolution with my work gmail. Send and receive no issues. When I am at my father-in-law's place, evolution cannot send email, it throws this error: Error while Sending message. HELO command failed: Peer failed to perform TLS handshake Now, I get that message in the office maybe once every thousand mails or so. At my father-in-law's place I have to manually flush the outbox continually until eventually a single email will spool out. I have to do this with each mail. On average I have to manually flush over 200 times to get one successful send. The physical links are all Singnet GPON (Gigabit Passive Optical Network) at the following speeds: Office: 30Mbps, Home: 500Mbps, Father-in-laws: 1Gbps. This is a weird one. In the office I am always connected over Ethernet. At home always over 802.11b/g/a/n. At my father-in-laws I'm connected using 802.11 ac. I have tried fiddling with MTU values but that changed nothing. Looking for some ideas on troubleshooting this. Cheers, John |
