Error at during DATA / Email::Sender::Transport::SMTP

talexb has asked for the wisdom of the Perl Monks concerning the following question:

I'm getting this error when trying to send an E-Mail using sendmail ..

Email::Sender::Transport::SMTP::_throw('Email::Sender::Transport::SMTP
+=HASH(0x564b90f0b378)', 'error at during DATA', 'Net::SMTP::_SSL=GLOB
+(0x564b8e0b7f10)') called at /usr/local/share/perl/5.34.0/Email/Sende
+r/Transport/SMTP.pm line 270
[download]

I'm a little puzzled, because I send other, similar messages using this module, and they all work fine. My only hypothesis is that the message might be too large for Outlook to handle. I see that there's a _hunk_size hard-coded to 2**20, and wonder if I could try reducing that hunk size to get this through.

Outlook is a client, not a mail server. Is this happening for a particular recipient? If so are there any 'special' characters in their email address or name? Can you show the code rather than the error message?	[reply]

Sorry -- I'm using smtp.office365.com, port 587 as the SMTP server .. I think of that as Outlook. I'm generating a report by sending a bunch of query results to Template::Toolkit process, then I'm sending the result. I just did a test run, and the output file (a web page) was 835K, so not huge. This is the code that sends the message, using ymd as the date and output as the output from the TT2 process: my $message = Email::Simple::Markdown->create( header => [ Subject => "Sage IC Issues to be fixed / $ymd", To => $list, Bcc => 'talexb@foobar.com', From => 'noreply@foobar.com' ], body => $output ); defined $message or die "Could not create message!"; try { sendmail( $message, { from => 'noreply@foobar.com', transport => Email::Sender::Transport::SMTP->new( { host => $EMail::Host, port => $EMail::Port, sasl_username => $EMail::User, sasl_password => $EMail::Password, ssl => 'starttls', } ) } ); } catch { warn "sending failed: $_"; }; [download] The complete error listing is here: sending failed: error at during DATA: [Net::SMTP::_SSL] Connection clo +sed Trace begun at /usr/local/share/perl/5.34.0/Email/Sender/Transport/SMT +P.pm line 259 Email::Sender::Transport::SMTP::_throw('Email::Sender::Transport::SMTP +=HASH(0x5591af605fd8)', 'error at during DATA', 'Net::SMTP::_SSL=GLOB +(0x5591b02e7890)') called at /usr/local/share/perl/5.34.0/Email/Sende +r/Transport/SMTP.pm line 270 Email::Sender::Transport::SMTP::__ANON__('error at during DATA') calle +d at /usr/local/share/perl/5.34.0/Email/Sender/Transport/SMTP.pm line + 324 Email::Sender::Transport::SMTP::send_email('Email::Sender::Transport:: +SMTP=HASH(0x5591af605fd8)', 'Email::Abstract=ARRAY(0x5591afd2b280)', +'HASH(0x5591afdc3f30)') called at /usr/local/share/perl/5.34.0/Email/ +Sender/Role/CommonSending.pm line 45 Email::Sender::Role::CommonSending::try {...} at /usr/local/share/per +l/5.34.0/Try/Tiny.pm line 102 eval {...} at /usr/local/share/perl/5.34.0/Try/Tiny.pm line 93 Try::Tiny::try('CODE(0x5591b02de808)', 'Try::Tiny::Catch=REF(0x5591afd +cfb90)') called at /usr/local/share/perl/5.34.0/Email/Sender/Role/Com +monSending.pm line 58 Email::Sender::Role::CommonSending::send('Email::Sender::Transport::SM +TP=HASH(0x5591af605fd8)', 'Email::Abstract=ARRAY(0x5591afd2b280)', 'H +ASH(0x5591b02de418)') called at /usr/local/share/perl/5.34.0/Email/Se +nder/Simple.pm line 119 Email::Sender::Simple::send_email('Email::Sender::Simple', 'Email::Abs +tract=ARRAY(0x5591afd2b280)', 'HASH(0x5591afdc3c90)') called at /usr/ +local/share/perl/5.34.0/Email/Sender/Role/CommonSending.pm line 45 Email::Sender::Role::CommonSending::try {...} at /usr/local/share/per +l/5.34.0/Try/Tiny.pm line 102 eval {...} at /usr/local/share/perl/5.34.0/Try/Tiny.pm line 93 Try::Tiny::try('CODE(0x5591afdc3fd8)', 'Try::Tiny::Catch=REF(0x5591afc +c9ea8)') called at /usr/local/share/perl/5.34.0/Email/Sender/Role/Com +monSending.pm line 58 Email::Sender::Role::CommonSending::send('Email::Sender::Simple', 'Ema +il::Simple::Markdown=HASH(0x5591afcc2fc0)', 'HASH(0x5591af605f30)') c +alled at /usr/local/share/perl/5.34.0/Sub/Exporter/Util.pm line 57 Sub::Exporter::Util::__ANON__('Email::Simple::Markdown=HASH(0x5591afcc +2fc0)', 'HASH(0x5591af605f30)') called at sage_issues.pl line 175 main::try {...} at /usr/local/share/perl/5.34.0/Try/Tiny.pm line 102 eval {...} at /usr/local/share/perl/5.34.0/Try/Tiny.pm line 93 Try::Tiny::try('CODE(0x5591afcb89c0)', 'Try::Tiny::Catch=REF(0x5591ad4 +ae5a0)') called at script.pl line 42 [download] Alex / talexb / Toronto Thanks PJ.

What does the SMTP server complain about that causes E'S'T'SMTP to croak? That is say log for the exchange between the client & server is missing.	[reply]

I'm afraid there are different measures. Wouldn't any new user be grilled here when providing such incomplete information? Greetings, 🐻 `$gryYup$d0ylprbpriprrYpkJl2xyl~rzg??P~5lp2hyl0p$`	[reply]
