Fri, 10 Apr 2026 14:08:40 +0000 https://bugs.horde.org/ticket/10080 Messages sent through SMTP server are truncated When sending messages through a SMTP server, the messages are truncated and following message is logged around the same time: May 14 16:37:29 mail HORDE: HORDE [imp] PHP ERROR: strlen() expects parameter 1 to be string, resource given [pid 9285 on line 862 of "/usr/share/php5/PEAR/Net/SMTP.php"] Using the local sendmail binary, all is well. But since we would like to use SASL authentication to determine if a user is allowed to use a From address (which worked flawlessly in H3), the SMTP server is a more convenient way.

Attached the message that is received.

Horde_Mail clearly indicates the minimum version is 1.4.0. Mon, 16 May 2011 17:01:29 +0000 https://bugs.horde.org/ticket/10080#t64691
