Re: [libreoffice-users] Mail bounce: alarmaxjag -AT- gmail.com [Was: How can I rejoin this list please?]

Hi Budge,

I suspected (and still suspect) that the mail configuration for alarmaxjag@gmail.com is at least 
partly implicated in the problem, because the list probably (almost surely?) has other gmail users 
(the list admin could confirm that), none of which bounce posts. IAC, (a) I have no problem sending 
mail for the account I'm currently using to my gmail account, which (b) has /no/ handling by an 
outlook.com server.

I also suspected that the list SMTP server might be implicated, because and my direct mail to 
alarmaxjag@gmail.com seemed to be received normally (as I expected from my own gmail account).  
However, 10 hours(!) after sending that, I also got a bounce response to my direct mail, so the 
problem is not limited to list mail. Moreover, the long delay on my DM bounce adds to the 
strangeness: what kind of mail server takes so long to issue a bounce error message? - curiouser 
and curiouser - again, though, it was not a /gmail/ bounce. IAC, I forwarded that bounce to my ISP 
for response and, like you, will post the results.

Kind regards,
John
