sendemail issues after upgrading to 23.04

I have found a work around to my issue. I'm not sure it is the best option and do not what other issues it might cause. I copied the SSL.pm from ubuntu version 22.10 to 23.04 and everything is working now. I did verify that it is using tls.

Please let me know if anyone knows any security or other issues with this workaround

lines in SSL.pm 790 if ( ! defined $host ) { 791 if ( $host = $arg_hash->{PeerAddr} || $arg_hash->{PeerHost} ) { 792 $host =~s{^ 793 (?: 794 ([^:[]+) | # ipv4|host 795 ([(.*)]) # [ipv6|host] 796 ) 797 (:[\w-]+)? # optional :port 798 $}{$1$2}x; # ipv4|host|ipv6 799 } 780 }

I have been using sendemail with no issues with ubuntu 22.10 desktop-amd64 but when I upgraded to 23.04 desktop-amd64 I get the following error. I have tried suggestions to add smtp.gmail.com ip address to local host file without success. The following is the command I was using with the output with the error. All the updates have been installed

sendemail -v -f <account>@gmail.com -t <account>@comcast.net -s smtp.gmail.com:587 -u "Update Backup Information" -m Update-List -a file.txt -xu <account>@gmail.com -xp <password> -o tls=yes

Output from command

Can you provide any suggestions or a solution to my issue?

Take a look at line 792 (and lines before/after) of `/usr/share/perl5/IO/Socket/SSL.pm` which may give you a clue as to which value the perl is saying is uninitialized. Maybe edit your question to include the code snippet around that line.

I have the same problem, and it's present also in debian 12 (bookworm)

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
