Hello, My Debian Sid system, including its networking system, has been working fine for a while. Recently, Gmail has not been working properly on the system: sending (via SMTP with SSL) times out, and receiving (via POP3 and IMAP) takes abnormally long. Today I finally made some efforts to understand what's going on. Here's what I know / understand / have been able to establish:
1) My ISP provides me with only IPv4, not IPv6. 2) Trying to send email through Gmail using "smtp.gmail.com", via Sylpheed and Swaks, times out without getting anywhere. For example: $ swaks -t cele...@gmail.com -s smtp.gmail.com:587 -tls -a LOGIN Username: celejar Password: ******** === Trying smtp.gmail.com:587... *** Error connecting to smtp.gmail.com:587: *** IO::Socket::INET6: connect: timeout 3) Forcing the use of IPv4 fixes the timeout problem. In particular, both of the following work (in the second command, the IPv4 address is the one returned by "dig" and "host" for "smtp.gmail.com"): $ swaks -t cele...@gmail.com -4 -s smtp.gmail.com:587 -tls -a LOGIN $ swaks -t cele...@gmail.com -s 142.251.163.109:587 -tls -a LOGIN So, what's going on here? I suppose I don't really need IPv6 on my system, but everything I've read says that it should be left enabled and not disabled. Is something misconfigured on my system, is this a Gmail problem, or am I missing something else? -- Celejar
