Tried the developers/proposed checkoff, but the 239systemd.. package is still not available. In any case, Ubuntu 18.04 has problems connecting with smtp.comcast.net (through evolution, recommended port 587). The error trying to send an email is:
An error occurred while sending, how do you want to proceed... "The reported error was "Could not connect to smtp.comcast.net: Network is unreadable". But of course it is, ping and dig both work (see below). Note that unlike the pop3, imap, (and mail) .comcast.net names, smtp DNS lookup results are small, one CNAME and one A , so bug 1804487 probably does not apply. $ ping smtp.comcast.net PING smtp.g.comcast.net (96.114.157.81) 56(84) bytes of data. 64 bytes from omta-po.sys.comcast.net (96.114.157.81): icmp_seq=1 ttl=56 time=39.3 ms 64 bytes from omta-po.sys.comcast.net (96.114.157.81): icmp_seq=2 ttl=56 time=40.6 ms $ dig smtp.comcast.net ; <<>> DiG 9.11.3-1ubuntu1.3-Ubuntu <<>> smtp.comcast.net ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 39553 ;; flags: qr rd ra; QUERY: 1, ANSWER: 2, AUTHORITY: 0, ADDITIONAL: 1 ;; OPT PSEUDOSECTION: ; EDNS: version: 0, flags:; udp: 65494 ;; QUESTION SECTION: ;smtp.comcast.net.
