I am trying to send mail with php using the PEAR Mail_queue package. It should be working, and it appeared to work twice, but for some reason I keep getting the following error response from qmail:
DEBUG: Recv: 220 domain.com - Welcome to Qmail ESMTP DEBUG: Send: EHLO localhost DEBUG: Recv: 250-domain.com - Welcome to Qmail DEBUG: Recv: 250-PIPELINING DEBUG: Recv: 250-8BITMIME DEBUG: Recv: 250-SIZE 20971520 DEBUG: Recv: 250-AUTH LOGIN PLAIN CRAM-MD5 DEBUG: Recv: 250 STARTTLS DEBUG: Send: STARTTLS DEBUG: Recv: 502 unimplemented (#5.5.1)
Any ideas? I am new to getting my hands dirty with SMTP as well as qmail, and this is the first time I've tried using PEAR for anything so I'm having trouble pinpointing where the problem lies.
